With this code path, pmbootstrap would start a distccd + sshd in the
native chroot, and configure it so it runs the cross compiler. The
foreign arch chroots would then call this cross compiler from localhost
by calling the distcc client instead of gcc.
This code has been obsoleted by the much simpler crossdirect in 2019.
Let's finally remove it.

pmbootstrap netboot command exposes the generated vendor-codename.img
rootfs through nbd interface so that device can mount it and boot
postmarketOS without having any storage medium at all.

Replace "args.cache" with a global variable in order to
avoid passing "args" to all functions. This is a step to get rid of this
args-passed-to-all-functions pattern in pmbootstrap.

Add initial support for the on-device installer in pmbootstrap. Let
pmbootstrap create a regular split image, then prepare a new installer
rootfs and copy the previously generated rootfs image into the installer
rootfs. Put the installer rootfs into a new image, with reserved space.
There is more to do from here, such as disabling the generation of the
user account when using --ondev. But this requires support in
postmarketos-ondev first, so let's build that iteratively.

Migrate to workdir version 5 and move already built packages into the edge
channel subdir, for example:
$WORK/packages/x86_64/hello-world-1-r5.apk
to:
$WORK/packages/edge/x86_64/hello-world-1-r5.apk
The build.postmarketos.org code has already been adjusted to find built
packages in either directory structure.
Whenever initializing new chroots, save the date in $WORK/workdir.cfg.
Add pmb.config.workdir.chroots_outdated() to check if it's time to zap
the chroots or not (since we don't update them automatically). Mark them
as outdated after two days.
This will be the first check in "pmbootstrap status" (future patches).

While at it, also remove unnecessary "#!/usr/bin/env python3" in files
that only get imported, and adjust other empty/comment lines in the
beginnings of the files for consistency.
This makes files easier to read, and makes the pmbootstrap codebase more
consistent with the build.postmarketos.org codebase.
Rust packaging is new and still a bit weird in Alpine and postmarketOS.
As of writing, we only have one package (squeekboard), and use cargo to
download the source of all dependencies at build time (several git
repositories!) and compile it. Usually, this is a no-go, but at least
until this is resolved properly, let's cache the downloads as suggested
in: https://doc.rust-lang.org/cargo/guide/cargo-home.html

Move find_aport() and find_aport_guess_main() from pmb/build/other.py
to the new file pmb/helpers/pmaports.py.
Finding aports is not only needed when building packages, hence it
makes sense to move it out of pmb.build. The pmb/helpers/pmaports.py
file will have more pmaports related functions in a follow up commit.
`-m` is for deleting local compiled packages, for which there is no
aport with the same version. Prior to this change, this only worked
for packages where no aport exists, or for packages that are newer
than the aports.
That is, because we used the usual APKINDEX parsing logic, which
ignores old packages in the APKINDEX and only returns the one with the
highest version (that makes sense during dependency resolution).
Changes:
* New `pmb.parse.apkindex.parse_blocks()` function that returns a raw
list of blocks, instead of the dict with removed duplicates with
lower version you get from the usual `.parse()` function.
* Renamed each of the zap flags and their descriptions to make clear
what they are doing now.
```
short long (old) long (new)
-p --packages --pkgs-local
-m --mismatch-bins --pkgs-local-mismatch
-o, --old-bins --pkgs-online-mismatch
```
Without this fix, `pmbootstrap zap -m` fails with:
File "/home/user/code/pmbootstrap/pmb/__init__.py", line 61, in main
getattr(frontend, args.action)(args)
File "/home/user/code/pmbootstrap/pmb/helpers/frontend.py", line 322, in zap
distfiles=args.distfiles)
File "/home/user/code/pmbootstrap/pmb/chroot/zap.py", line 54, in zap
zap_mismatch_bins(args, confirm, dry)
File "/home/user/code/pmbootstrap/pmb/chroot/zap.py", line 110, in zap_mismatch_bins
if pkgname != bin_data["pkgname"]:
KeyError: 'pkgname'
zap -m:
* APKINDEX parsing: parse the "origin" field as well, so we know
where a subpackage comes from
* pmbootstrap zap -m: properly delete all packages, that do not
have an aport or where the aport has another version. This also
works with subpackages now,
we use the origin field to resolve it.
* Only reindex when packages have been deleted in "zap -m"
zap in general:
* Show the amount of cleared up space after the deletion instead
of "Done"
* Print "Shutdown complete" to "pmbootstrap log" instead of stdout
(we need to call it twice during zap now to get the space
calculation right)
* Add `--dry` argument to `pmbootstrap zap` (this was very useful
for debugging) to list the packages/chroots that would get
deleted
* Roughly output the command that would get executed to delete
files, so it's obvious what's going on in --dry mode. (% rm ...)
This adds a new option to `zap`: `-m / --mismatch-bins`
When set, any binary apks in the work directory packages folder will be
removed if their version differs from the version in the relevant
APKBUILD in aports.
This extends zap() to add a 'no_confirm' option (False by default), and
zap() is now called by init with no_confirm=True to automatically zap
any existing chroots after the user runs init. This helps insure that
what is installed in the chroots is exactly what the user expects after
setting options in init.
Additionally, we create `cache_http` to verify write access to the work
folder instead of `chroot_native`. So we can ask for zapping only if
no chroot folder exists.
I've replaced all instances in the code of `os.path.abspath`
with `os.path.realpath`, as this does the same as `abspath`
plus resolving symlinks.

* Validate all inputs from `pmbootstrap init`
* Add a new `confirm()` function, that validates input of yes/no
questions properly
* All questions loop until they have a valid answer now
TLDR: Always rebuild/install packages when something changed when executing "pmbootstrap install/initfs/flash", more speed in dependency resolution.
---
pmbootstrap has already gotten some support for "timestamp based rebuilds", which modifies the logic for when packages should be rebuilt. It doesn't only consider packages outdated with old pkgver/pkgrel combinations, but also packages, where a source file has a newer timestamp, than the built package has.
I've found out, that this can lead to more rebuilds than expected. For example, when you check out the pmbootstrap git repository again into another folder, although you have already built packages. Then all files have the timestamp of the checkout, and the packages will appear to be outdated. While this is not largely a concern now, this will become a problem once we have a binary package repository, because then the packages from the binary repo will always seem to be outdated, if you just freshly checked out the repository.
To combat this, git gets asked if the files from the aport we're looking at are in sync with upstream, or not. Only when the files are not in sync with upstream and the timestamps of the sources are newer, a rebuild gets triggered from now on.
In case this logic should fail, I've added an option during "pmbootstrap init" where you can enable or disable the "timestamp based rebuilds" option.
In addition to that, this commit also works on fixing #120: packages do not get updated in "pmbootstrap install" after they have been rebuilt. For this to work, we specify all packages explicitly for abuild, instead of letting abuild do the resolving. This feature will also work with the "timestamp based rebuilds".
This commit also fixes the working_dir argument in pmb.helpers.run.user, which was simply ignored before.
Finally, the performance of the dependency resolution is faster again (when compared to the current version in master), because the parsed apkbuilds and finding the aport by pkgname gets cached during one pmbootstrap call (in args.cache, which also makes it easy to put fake data there in testcases).
The new dependency resolution code can output lots of verbose messages for debugging by specifying the `-v` parameter. The meaning of that changed, it used to output the file names where log messages come from, but no one seemed to use that anyway.
* pmb/challenge/apk.py had to be renamed to pmb/challenge/apk_file.py,
so the "internal" functions of that file could be accessed, while
still providing the short notation pmb.challenge.apk().
* zap asks for each buildroot_* chroot, if you want to remove it, not
only for the one with the device arch
* add new pmb.chroot.tempfolder() function, that creates a temporary
folder, that belongs to "user" and deletes it, if it already exists.
this function gets used in a few challenge testcases.
