* Rename pmb/build/package.py to pmb/build/_package.py, so we can
access the functions it contains in testcases, and still use
pmb.build.package()
* Refactor the entire file. Instead of one big function that does
too many things, we have many small ones now, that are tested
in the testsuite and easier to modify
* Whenever building a package, pmbootstrap does not only build and
install the "makedepends" (like we did before), now it does the
same for the "depends". That's required to be compatible with
abuild. The old behavior can still be used with 'pmbootstrap
build --ignore-depends'.
* Because of that change, noarch packages can no longer be built in
the native chroot if we need them for a foreign chroot. A device-
package depending on a kernel would pull in the same kernel for
the native architecture otherwise.
* Running 'pmbootstrap build device-...' without '--ignore-depends'
and without a matching '--arch' displays a note that explains
this change to the user and tells how to use it instead.
* Noarch packages no longer get symlinked. That was only
implemented for packages built in the native chroot, and now that
is not always the case anymore. Symlinking these packages creates
packages with broken dependencies anyway (e.g.
device-samsung-i9100 can't be installed in x86_64, because
linux-samsung-i9100 is armhf only).
* Rename "carch" to "arch" wherever used. Naming it "carch"
sometimes is confusing with no benefit.
* Add a testcase for the aarch64 qemu workaround (because it failed
first and I needed to know for sure if it is working again).
* Improved some verbose logging, which helped with development of
this feature.
* Removed the old "build" test case (which was disabled in
testcases_fast.sh) as the new "build_package" test case covers its
functionallity.
* Only build indexes if the packages folder exists for that arch (Travis
couldn't run a test case otherwise)
* Allow to specify a custom username in "pmbootstrap init"
* Build chroots have "pmos" instead of "user" as username now
* Installation user UID is 1000 now (as in all other Linux distributions)
* Adjust autologins
* postmarketos-base: enable wheel group for sudo, removed previous sudoers file
* Implement safe upgrade path:
We save the version of the work folder format now, in $WORK/version.
When this file does not exist, it defaults to 0.
In case it does not match the currently required version
(pmb.config.work_version), then ask the user if it should
automatically be upgraded.
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.

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.
