Cease merging pmbootstrap.cfg into args, implement a Context type to let
us pull globals out of thin air (as an intermediate workaround) and rip
args out of a lot of the codebase.
This is just a first pass, after this we can split all the state that
leaked over into Context into types with narrower scopes (like a
BuildContext(), etc).

With the new chroot type, we can now write fancy paths in the pythonic
way. Convert most of the codebase over, as well as adding various other
type hints.

Introduce a new module: pmb.core to contain explicitly typed pmbootstrap
API. The first component being Suffix and SuffixType. This explicitly
defines what suffixes are possible, future changes should aim to further
constrain this API (e.g. by validating against available device
codenames or architectures for buildroot suffixes).
Additionally, migrate the entire codebase over to using pathlib.Path.
This is a relatively new part of the Python standard library that uses a
more object oriented model for path handling. It also uses strong type
hinting and has other features that make it much cleaner and easier to
work with than pure f-strings. The Chroot class overloads the "/"
operator the same way the Path object does, allowing one to write paths
relative to a given chroot as:
builddir = chroot / "home/pmos/build"
The Chroot class also has a string representation ("native", or
"rootfs_valve-jupiter"), and a .path property for directly accessing the
absolute path (as a Path object).
The general idea here is to encapsulate common patterns into type hinted
code, and gradually reduce the amount of assumptions made around the
codebase so that future changes are easier to implement.
As the chroot suffixes are now part of the Chroot class, we also
implement validation for them, this encodes the rules on suffix naming
and will cause a runtime exception if a suffix doesn't follow the rules.
Add the following question to "pmbootstrap init":
[22:12:57] Based on your UI selection, 'default' will result in installing systemd.
[22:12:57] Install systemd? (default/always/never) [default]:
Determine whether the UI prefers to have systemd or not, based on
"pmb:systemd" in the UI package's APKBUILD.
Determine whether the currently selected branch supports systemd, by
checking for a "[repo:systemd]" section in pmaports.cfg. This section
will also contain bootstrap information, to be used in 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.
This way we could give the user a rough idea what will be installed,
and also use this to display a short warning about long compile times
(e.g. until the plasma mobile stuff is upstreamed).
Thanks, craftyguy!
- UI is selectable with `pmbootstrap init`. Currently only 'weston' and 'none' are options. It'll automatically pick up any new `postmarketos-ui-*` packages added at later dates.
- splits off weston packages install from postmarketos-base and puts
them into postmarketos-ui-weston. Also note that NO weston packages are
installed by "pmbootstrap install" by default unless the user selects a ui in the `init`
- configuration of weston is now in postmarketos-ui-weston.
- the demos have been spun off to `postmarketos-demos`, and `postmarketos-ui-weston` lists this package as a dependency.
