Here are the changes necessary in pmbootstrap to make proprietary
software installed onto the device (firmware and userspace drivers)
optional (#756). To full close the issue, we need to apply this concept
to all device packages we already have in a follow-up PR.
Changes:
* New config file options nonfree_firmware and nonfree_userland, which
we ask for during "pmbootstrap init" if there are non-free components
for the selected device.
* We find that out by checking the APKBUILD's subpakages: The non-free
packages are called $pkgname-nonfree-firmware and
$pkgname-nonfree-userland.
* During "pmbootstrap init" we also show the pkgdesc of these
subpackages. Parsing that is implemented in
pmb.parse._apkbuild.subpkgdesc(). It was not implemented as part of
the regular APKBUILD parsing, as this would need a change in the
output format, and it is a lot *less* code if done like in this
commit.
* pmb/parse/apkbuild.py was renamed to _apkbuild.py, and
pmb/install/install.py to _install.py: needed to call the function in
the usual way (e.g. pmb.parse.apkbuild()) but still being able to
test the individual functions from these files in the test suite.
We did the same thing for pmb/build/_package.py already.
* Install: New function get_nonfree_packages() returns the non-free
packages that will be installed, based on the user's choice in
"pmbootstrap init" and on the subpackages the device has.
* Added test cases and test data (APKBUILDs) for all new code,
refactored test/test_questions.py to have multiple functions for
testing the various questions / question types from
"pmbootstrap init" instead of having it all in one big function.
This allows to use another aport folder for testing the new
non-free related questions in init.
