Oliver Smith 51bdc24315 Properly rebuild/install packages when something changed (Fix #120, #108, #131) (#129)
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 It doesn't only consider packages outdated with old pkgver/pkgrel combinations, but also packages, where a source file has a newer timestamp, than the built package has.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 Then all files have the timestamp of the checkout, and the packages will appear to be outdated.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problem once we have a binary package repository, because then the packages from the binary repo will always seem to be outdated, if you just freshly checked out the repository.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.chroot.apk.installed(): use apk's internal database
...instead of running apk every time to get the list of installed
packages and their versions. The internal package database from
apk has the same format, as the extracted APKINDEX file (except
that it has more key-value pairs, which we ignore/do not need
right now). So the APKINDEX code has been extended to parse both
tar-packed APKINDEX files and regular text files in the APKINDEX
format.

This is required for #108, for a better detection of outdated
packages (because the internal package database  saves the
package's timestamp, too). A nice benefit is, that this is faster
than calling apk every time and it doesn't fill up the log as much.

I've also used this improved function for determining the apk
version (for the outdated version check), and I've deleted
pmb.parse.other.package_split(), as it is not needed anymore.

Update min apk version/add more apk version checks
* Minimum version: 2.7.2 (which fixes two CVEs)
* Check the minimum apk version before doing something with apk and
  before entering the chroot manually (previously, it has just checked
  the apk-tools-static version, which gets used to set up the chroot)
* Reword the message for an outdated APK version. Most likely it is
  just the outdated http cache, instead of a man-in-the-middle attack.

apk.installed(): Retuns all packages and versions now
pmb.chroot.apk.installed() used to return only the explicitly installed
packages. This is not good enough for the initfs check functions (and
especially for the "lazy reproducible builds", from which branch this
commit was cherry picked).

This commit introduces more noise for the logfile - if this becomes
a problem, raise your voice in the issues tracker and we'll do something
about it.

(This commit also changes minor code styling in other files, I did
not run autopep8 last time, because flake8 didn't complain...)

Fix #68: properly update the device chroot in the install step
* build all dependencies, that have a newer version
* upgrade all packages inside the chroot
