pmb: add -f (force) parameter to bootimg_analyze
We are analyzing the `boot.img` with `file` before we send it to
`unpackbootimg`. File does not recognize all kinds of `boot.img` files,
which `unpackbootimg` can extract, so we need a way to skip this check.

Details:
* Add `-f` parameter, continues extraction with a warning if the file
  seems to be invalid
* Tell the user that `-f` can be used if the `boot.img` is invalid and
  it's not specified
* Consistent spelling of `boot.img` instead of `bootimg` in messages

Fixes #1608

pmb: Add user to plugdev group and create it
This allows the user to talk to networkmanager to manage the system
connections. As it is mentioned in networkmanager pre-install.

```
Executing networkmanager-1.10.6-r0.pre-install
  *
  * To setup system connections, regular users must be member of 'plugdev' group.
```

The plugdev group gets created in the post-install hook of
networkmanager. Not all UIs depend on networkmanager, which means that
the group may not exist at installation time when we try to add the
user to the group in the python code. Therefore we create the group
first.

pmbootstrap kconfig edit: support $builddir and $srcdir/build (#1573)
The linux APKBUILDs write the kernel config either to `$builddir`
(default from the template) or `$srcdir/build` (legacy, and I reverted
to that in #1556, which was not the proper fix for this regression).

With this commit, `pmbootstrap kconfig edit` is able to edit both
versions, and prints a note when the APKBUILD is still using the old
style.

Fix conflict with mkbootimg and android-tools (#1557)
Alpine ships `mkbootimg` with the `android-tools` package now. This
conflicts with the `mkbootimg` fork from osm0sis (see #441).

Changes:
* Rename `mkbootimg` to `mkbootimg-osm0sis` (aport and binary name)
* `mkbootimg-osm0sis`: provides `mkbootimg` now (so we don't need to
  change all the device aports), update version to 2018.05.10
* Adjust our `mkinitfs` script to call `mkbootimg-osm0sis`
* Better aport description
* pkgrel_bump testcase: don't fail on deleted aport

aportgen linux: always override KBUILD_OUTPUT (#1556)
Some kernels have a different `KBUILD_OUTPUT` path (e.g. #1551). When
the output path is different from `$srcdir/build`, then
`pmbootstrap kconfig edit` will not work (same with the previous
`pmbootstrap menuconfig` implementation).

This commit forces the output path to be `$srcdir/build` in the template
for new kernel aports, so we won't have that issue with future ports.

Allow DEVTMPFS_MOUNT in kernel config (#1548)
It is important, that we have DEVTMPFS enabled in the kernel config. But
it  does not hurt to have DEVTMPFS_MOUNT enabled as well, and some of
Alpine's kernel configs have that by default. This commit removes the
check that forbids the option in kernel configs, so we can fork the
raspberry pi kernel package from Alpine without changing unrelated
options.

steamport 30df0725ca menuconfig: add gconfig/xconfig support (#1509)
* change "pmbootstrap kconfig_check" to "pmbootstrap kconfig check"
* change "pmbootstrap menuconfig" to "pmbootstrap kconfig edit [-x|-g]"
  (with legacy alias, because the first syntax was referenced to a lot)
* enable X11 interfaces: -x: xconfig, -g: gconfig
* new function to copy the xauthority file:
  pmb.chroot.other.copy_xauthority()
* remove menufconfig() function from the kernel template and all kernel
  aports ([skip ci] because it would rebuild all kernels and run out of
  time). Alpine has dropped this as well, and it wouldn't work with the
  new code anyway.

gcc-*: fix compiling in strict mode [skip ci] (#1468)
Due to changes in abuild, our `gcc-armhf` etc. packages did not build
when using strict mode (i.e. `pmbootstrap build --strict gcc-armhf`)
anymore.

Changes:
* Set `CBUILDDIR=/`, so apk can read a valid package index from there
* Directly set `_cross_configure`, so it does not use CBUILDDIR anymore
* Set `BOOTSTRAP="nobuildbase"` to prevent apk from installing
  `build-base-armhf` etc. (these don't exist in pmOS)
* Remove legacy code for lazy reproducible builds that wrapped
  `package()`

Only print 'pmbootstrap log' msg to stdout (#1453)
Prevent the "Run 'pmbootstrap log' for details" message from being
written to the log file that gets read with "pmbootstrap log". Because
when the output of "pmbootstrap log" is pasted somewhere and people
analyze it, the message sounds like this is not the output of
"pmbootstrap log" (like it happened the other day in #postmarketOS).

Daniele Debernardi 827a60cd25 Add install flag to generate separate boot and system images (#1442)
* Usage: pmbootstrap install --split
* Make obvious that export is the next step when split images are created
* Fix note for missing rootfs image on export
  * Change wording from "system image" to "rootfs image"
  * The idea was to show the note only when the rootfs image was not
    generated yet. But this was broken, because the path we checked for
    was missing the chroot path prefix (which is added now).
  * Also don't display the message, when the split image files exist

Recreate device nodes in chroot after shutdown (#1447)
Device nodes in the chroots get created in a tmpfs, so they can be
created even if the filesystem where the chroot resides does not
support device nodes (#1317). In "pmbootstrap shutdown" we umount the
`dev` folder, which means all device nodes that were created inside
this folder are gone. This commit changes the code to actually recreate
the device nodes when using the chroot again.

Details:
* move `pmb.chroot.init.create_device_nodes` to
  `pmb.chroot.mount.crete_device_nodes`
* don't call it in `pmb.chroot.init()` anymore, but in
  `pmb.chroot.mount_dev_tmpfs()`
* Create the `null` device as well (`apk --initdb` also creates it on
  `init`, but we don't call it after `shutdown`)

Fix binfmt_misc check (#1449)
We require binfmt_misc to run programs of foreign architectures (e.g.
armhf) with QEMU. This is set up by default in most distributions, but
in some (e.g. Alpine, Void) it needs to be configured manually (see
 the troubleshooting page in the wiki).

We have a check in place, which points to that troubleshooting wiki
page. However, the check was flawed, because we assumed the binfmt_misc
folder would not exist.

Thanks to @fxkrait for making the fix and for testing it!

msm-fb-refresher: use initfs hook (#1438)
The `msm-fb-refresher` updates the screen for msm based devices. It is
not needed for all devices, so we had some extra code in the initramfs,
that would only add it when the `deviceinfo_msm_refresher` variable was
set. However, we are able now to add files to initramfs hooks, so this
hack can be removed and simplify everything.

Changes:
* Remove `deviceinfo_msm_refresher` from all deviceinfos
* Add sanity check for it
* Move all `deviceinfo` sanity checks to an extra function
* `postmarketos-mkinitfs`: remove code for msm refresher
* `msm-fb-refresher`: add initramfs hook

Set all of user's groups in "pmbootstrap install" (#1432)
The postmarketos-base package used to make the user part of the "video"
and "audio" groups. However, this did not work reliably, and we were
adding the "wheel" group in "pmbootstrap install" anyway.

Now all groups get added in "pmbootstrap install", and the names of the
groups have been moved to `pmb.config.install_user_groups`.

Add envkernel.sh: instant mainlining environment (#1424)
Changes:
* `helpers/envkernel.sh`:
  * installs everything needed for kernel compilation in the native
    chroot
  * mounts the kernel source to `/mnt/linux` inside the chroot
  * creates `/mnt/linux/.output` and chowns it to the `pmos` user, that
    folder will be used for the kernel build output
  * sets up aliases for `make`, `pmbootstrap`, `pmbroot`, `kernelroot`
* new action `pmbootstrap work_migrate`: does the interactive work
  folder migration if necessary, otherwise it doesn't output anything
  * when calling this first, we can safely use all other commands
    non-interactively without showing the output

Benefits:
* Fast setup (especially for people who are new to kernel
  compilation
  * No need to figure out distribution specific package names
    (cross compilers!)
  * No need to do a test build just to verify that the right
    packages are installed
* Less error prone
  * The right dependencies are always installed
  * `ARCH` and `CROSS_COMPILE` variables always get set automatically
    and based on `deviceinfo_arch`
  * If the build environment is broken for some reason, just zap and
    start over
* Easy to reproduce problems

Notes:
* `make menuconfig` works as well
* Sourcing was tested with `zsh`, `bash` and `fish`, it should be easy to
  extend for other shells

Fix building packages when git is in chroot
Building packages without git installed caused error messages from git
appearing on the screen, and I patched it upstream (see #1209).
However, this introduced a regression: when git *is* installed and the
aport folder *is not* part of a git repository (like we do it with
pmbootstrap), the build gets aborted now with git complaining that
the folder is not a valid git folder.

But the only case where this happens is, when abuild is trying to
include the git repositories' commit hash for the APKINDEX description.
This pmbootstrap commit hardcodes "postmarketOS" as APKINDEX
description, so it does not fail anymore.

"pkgrel_bump --auto": Handle subpackages properly (#1388)
`pmbootstrap pkgrel_bump --auto` automatically increases the pkgrel for
packages linking against libraries, which don't exist anymore (because
the soname has been changed). The feature is explained in detail in

The previous implementation did not detect soname breakage, when a
subpackage linked against a certain library, but the main package
did not (e.g. `qt5-qtbase-mysql` and `qt5-qtbase`). This was, because
we iterated over the aports/* to find the packages to be checked.

To fix this, we are iterating over the packages found in the APKINDEX
files instead (of both the locally compiled packages and the downloaded
index from the pmOS mirror).

Details:
* `pmb/helpers/pkgrel_bump.py`:
  * Rewrite `auto_apkindex_package()` to act upon a given parsed
    `aport` and `apk` (from the index) instead of finding the `apk`
    dict by itself (we need it earlier anyway).
  * Rewrite `auto()` to iterate over APKINDEX files instead of aports
    * Skip packages already found, so the `pkgrel` does not get
      increased multiple times when the same package was found in
      multipe index files.
* Put the package name at the beginning of the log messages to make
  them more readable
* testdata: Create a new `testsubpkg` aport, where only the subpackage
  links against `testlib`
* Adjust testing code to test everything with `testsubpkg` as well.

NOTE: This makes the command a bit slower, but we could improve
performance again by smart caching of `pmb.parse.apkindex.depends()`.
This could come in a future PR, the important part here is that the
command is bug-free again with this fix.

pmbootstrap init: kernel selection / remove linux-pmos-lts (#1363)
* As discussed in IRC/matrix, we're removing `linux-postmarketos-lts`
  for now. The kernel isn't used right now, and we save lots of
  maintenance effort with not updating it every week or so.
* new config option `"kernel"` with possible values:
  `"downstream", "mainline", "stable"` (downstream is always
  `linux-$devicename`)
* ask for the kernel during `pmbootstrap init` if the device package
  has kernel subpackages and install it in `_install.py`
* postmarketos-mkinitfs: display note instead of exit with error when
  the `deviceinfo_dtb` file is missing (because we expect it to be
  missing for downstream kernels)
* device-sony-amami:
  * add kernel subpackages for downstream, mainline
  * set `deviceinfo_dtb`
* device-qemu-amd64: add kernel subpackages for stable, lts, mainline
* test cases and test data for new functions
* test case that checks all aports for right usage of the feature:
  * don't mix specifying kernels in depends *and* subpackages
  * 1 kernel in depends is maximum
  * kernel subpackages must have a valid name
  * Test if devices packages reference at least one kernel
* Remove `_build_device_depends_note()` which informs the user that
  `--ignore-depends` can be used with device packages to avoid building
  the kernel. The idea was to make the transition easier after a change
  we did months ago, and now the kernel doesn't always get built before
  building the device package so it's not relevant anymore.
* pmb/chroot/other.py:
  * Add autoinstall=True to kernel_flavors_installed(). When the flag
    is set, the function makes sure that at least one kernel for the
    device is installed.
  * Remove kernel_flavor_autodetect() function, wherever it was used,
    it has been replaced with kernel_flavors_installed()[0].
* pmb.helpers.frontend.py: remove code to install at least one kernel,
  kernel_flavors_installed() takes care of that now.

Fix dependency resolver being stuck after reboot (#1359)
When the native arch (e.g. `x86_64`) `APKINDEX` files are outdated, and
`pmbootstrap` gets instructed to build a linux package for a foreign
arch, then the `APKINDEX` cache did not get used anymore for the
current session. This means that every lookup of a package in an
`APKINDEX` caused the whole `APKINDEX` file to get parsed again instead
of using the cached version. This slowed it down so much that it felt
like `pmbootstrap` was looping forever.

How this happens in detail:
* Whenever pmbootstrap parses an `APKINDEX`, it fills up the
  `args.cache["apkindex"]` dict with the parsed information and the
  last modified date of the file.
* `pmbootstrap` checks the last modified date of the `APKINDEX` files
  and updates them if they are older than 4 hours.
* When the bug appeared, then the cache was already filled up, then an
  update happened and then `pmbootstrap` tried to read from the cache.
* So when reading from the `APKINDEX`, the cache gets ignored because
  the last modified date is different.
* Up to this commit, the cache does not get deleted and filled up
  again!

How to test:
Try these commands once without this commit, and then with this commit
applied:
```
$ sudo touch -m -t 201801010000 \
    ~/.local/var/pmbootstrap/cache_apk_x86_64/APKINDEX.*
$ pmbootstrap -v build linux-postmarketos-mainline --arch=armhf
```

Without the patch, you can see in `pmbootstrap log` that it is
resolving the dependencies properly, but very slowly. With the patch
the resolving happens almost instantly.

Package resolving: Don't fail on fuzzy versions (#1355)
When parsing the depends of entries in the APKINDEX file, we ignore
all operators (<, =, >). (This is enough for our use case, was we only
do the dependency resolving to check which packages need to be built
and `apk` does the dependency resolving again before installing
anything).

We did not ignore the ~ character for fuzzy version compares, this is
fixed with this commit.

pmbootstrap newapkbuild: Properly parse arguments (#1320)
* pmbootstrap newapkbuild: Properly parse arguments

The `pmbootstrap newapkbuild` action wraps Alpine's `newapkbuild`. We
used to directly pass all arguments to `newapkbuild` without verifying
in Python whether they make sense or not. However, as `newpakbuild`
doesn't do strict sanity checks on the arguments, it is easy to end up
with unexpected behavior when using the command for the first time.

For example, `newapkbuild` allows either specifying a PKGNAME or SRCURL
as last parameter, and also allows setting a PKGNAME with the `-n`
parameter. It only makes sense to use that option when passing a
SRCURL.

With this commit, we duplicate the optins that should be passed through
to `newapkbuild` and use argparse to fully sanitize the options and
display a help page (`pmbootstrap newapkbuild -h`) that is consistent
with the other help pages.

Details:
* The `-f` (force) flag does not get passed through anymore. Instead we
  use it in Python to skip asking if an existing aport should be
  overwritten (the aports are outside of the chroot, so `newapkbuild`
  can't handle it in a way that makes sense for pmbootstrap).
* Output of `newapkbuild` gets redirected to the log file now, as we
  don't need it to display a help page.
* Don't verify the pkgver while creating the new APKBUILD. When passing
  a SRCURL, the pkgver gets extracted from the end of the URL and may
  not have a valid format yet (but we want the APKBUILD anyway).
* Stored options passed through in `pmb/config/__init__.py` and use it
  in both `pmb/parse/arguments.py` and `pmb/helpers/frontend.py`.
* Only allow `-n` with SRCURL
* The postmarketOS aports folder gets specified with `--folder` now.
  That way the generated help page is much closer to the original one
  from `newapkbuild`. The default is `main`.
* Made the package type flags (CMake, autotools, ...) exclusive so only
  one of them can be specified

Fix aportgen without initializing buildenv
After initializing the build environment, the cache_distfiles folder
currently is writable by everyone (which is not ideal, fix following
soon). The aportgen code for `busybox-static-*` and `musl-*` copies
the foreign arch `.apk` file to the distfiles, but it executes this
action as regular user and not as root. This only works as long as
build initialization ran before (which may not be the case on Travis
and expecting this to run before is a bug in general).

With this commit, the copy action gets executed as root, so it works
in any case. I'm commiting this directly (without a PR), because it
is a super simple fix and it unblocks our continuous integration.

Local testing:
$ pmbootstrap -y zap
$ sudo rm -r ~/.local/var/pmbootstrap/cache_distfiles
$ pmbootstrap aportgen musl-armhf

aportgen: Gracefully handle old aports_upstream (#1291)
In order to get cross-compilers, we generate a few aports (e.g.
binutils-armhf, gcc-armhf) automatically from Alpine's aports.
pmbootstrap was already able to perform a git checkout of Alpine's
aports repository. But it needed to be manually updated. Otherwise
the `pmbootstrap aportgen` command could actually downgrade the aport
instead of updating it to the current version.

After thinking about adding a dedicated pmbootstrap command for
updating git repositories, I thought it would be better to not open
that can of worms (pmbootstrap as general git wrapper? no thanks).

The solution implemented here compares the upstream aport version of
the git checkout of a certain package (e.g. gcc for gcc-armhf) with the
version in Alpine's binary package APKINDEX. When the aport version is
lower than the binary package version, it shows the user how to update
the git repository with just one command:

    pmbootstrap chroot --add=git --user -- \
        git -C /mnt/pmbootstrap-git/aports_upstream pull

Changes:
* `pmb.aportgen.core.get_upstream_aport()`: new function, that returns
  the absolute path to the upstream aport on disk, after checking the
  version of the aport against the binary package.
* Use that new function in pmb.aportgen.gcc and pmb.aportgen.binutils
* New function `pmb.helpers.repo.alpine_apkindex_path()`: updates the
  APKINDEX if necessary and returns the absolute path to the APKINDEX.
  This code was basically present already, but not as function, so now
  we have a bit less overhead there.
* `pmbootstrap chroot`: new `--user` argument
* `pmb.parse.apkbuild`: make pkgname check optional, as it fails with
  the official gcc APKBUILD before we modify it (the current APKBUILD
  parser is not meant to be perfect, as this would require a full shell
  parsing implementation).
* Extended `test_aportgen.py` and enabled it by default in
  `testcases_fast.sh`.  Previously it was disabled due to traffic
  concerns (cloning the aports repo, but then again we do a full KDE
  plasma mobile installation in Travis now, so that shouldn't matter
  too much).
* `testcases_fast.sh`: With "test_aport_in_sync_with_git" removed
  from the disabled-by-default list (left over from timestamp based
  rebuilds), there were no more test cases disabled by default. I've
  changed it, so now the qemu_running_processes test case is disabled,
  and added an `--all` parameter to the script to disable no test
  cases. Travis runs with the `--all` parameter while it's useful to
  do a quick local test without `--all` in roughly 2 minutes instead of
  10.
* `aports/cross/binutils-*`: Fix `_mirror` variable to point to current
  default Alpine mirror (so the aportgen testcase runs through).

Properly escape commands in pmb.chroot.user() (#1316)
## Introduction
In #1302 we noticed that `pmb.chroot.user()` does not escape commands
properly: When passing one string with spaces, it would pass them as
two strings to the chroot. The use case is passing a description with
a space inside to `newapkbuild` with `pmboostrap newapkbuild`.

This is not a security issue, as we don't pass strings from untrusted
input to this function.

## Functions for running commands in pmbootstrap
To put the rest of the description in context: We have four high level
functions that run commands:
* `pmb.helpers.run.user()`
* `pmb.helpers.run.root()`
* `pmb.chroot.root()`
* `pmb.chroot.user()`

In addition, one low level function that the others invoke:
* `pmb.helpers.run.core()`

## Flawed test case
The issue described above did not get detected for so long, because we
have a test case in place since day one, which verifies that all of the
functions above escape everything properly:
* `test/test_shell_escape.py`

So the test case ran a given command through all these functions, and
compared the result each time. However, `pmb.chroot.root()`
modified the command variable (passed by reference) and did the
escaping already, which means `pmb.chroot.user()` running directly
afterwards only returns the right output when *not* doing any escaping.

Without questioning the accuracy of the test case, I've escaped
commands and environment variables with `shlex.quote()` *before*
passing them to `pmb.chroot.user()`. In retrospective this does not
make sense at all and is reverted with this commit.

## Environment variables
By coincidence, we have only passed custom environment variables to
`pmb.chroot.user()`, never to the other high level functions. This only
worked, because we did not do any escaping and the passed line gets
executed as shell command:
```
$ MYENV=test echo test2
test 2
```
If it was properly escaped as one shell command:
```
$ 'MYENV=test echo test2'
sh: MYENV=test echo test2: not found
```
So doing that clearly doesn't work anymore. I have added a new `env`
parameter to `pmb.chroot.user()` (and to all other high level functions
for consistency), where environment variables can be passed as a
dictionary. Then the function knows what to do and we end up with
properly escaped commands and environment variables.

## Details
* Add new `env` parameter to all high level command execution functions
* New `pmb.helpers.run.flat_cmd()` function, that takes a command as
  list and environment variables as dict, and creates a properly escaped
  flat string from the input.
* Use that function for proper escaping in all high level exec funcs
* Don't escape commands *before* passing them to `pmb.chroot.user()`
* Describe parameters of the command execution functions
* `pmbootstrap -v` writes the exact command to the log that was
  executed (in addition to the simplified form we always write down for
  readability)
* `test_shell_escape.py`: verify that the command passed by reference
  has not been modified, add a new test for strings with spaces, add
  tests for new function `pmb.helpers.run.flat_cmd()`
* Remove obsolete commend in `pmb.chroot.distccd` about environment
  variables, because we don't use any there anymore
* Add `TERM=xterm` to default environment variables in the chroot,
  so running ncurses applications like `menuconfig` and `nano` works out of
  the box
