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).

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.
Reimplement "pmbootstrap status" to be just a simple and useful status
overview. The previous version ran a bunch of checks every time, and
would fail on these even if pmaports was used for normal development:
* "non-official" branch checked out in pmaports
* pmaports.git is not clean
The information about aports.git was also considered not so useful upon
revisiting this command, since it is only used for "pmbootstrap
aportgen". Most users don't need this, and if the user runs this
command, it will tell if aports.git is outdated.
All of the above made the previous version unpleasant to use and I
suspect most people stopped using the command after trying it out a few
times and seeing the irrelevant but loud NOK complaints.
New version:
$ pmbootstrap status
Channel: edge (pmaports: master_staging_systemd)
Device: qemu-amd64 (x86_64, kernel: virt)
UI: console
systemd: no (default for selected UI)
Old version (without --details it only shows NOK checks):
$ pmbootstrap status --details

[00:55:20] DONE!
For UI packages that have pmb:systemd-never set:
* do not ask in "pmbootstrap init" whether to use systemd or not
* do not install systemd, even if the systemd option is set to "always"
The point of this is to not add maintenance burden to Sxmo (and possibly
other UIs who not wish to support systemd with postmarketOS), so users
don't install with this unsupported use case and report issues with it.
