This option will make pmbootstrap automatically zap chroots that are
initialized for the wrong channel, making it much faster to switch
between edge and systemd.

Get rid of config.mirror_alpine and mirrors_postmarketos and make sure
they get migrated over for existing users.
mirrors_postmarketos being a list was always a bit off, but now we have
per-aports mirrors which make a lot more sense for what we're trying to
do with systemd.

We now have support for having mirrors per-aports repo, drop the
mirrors_postmarketos arg from chroot.init and instead have
repo_bootstrap call apk.update_repository_list() explicitly to exclude
the mirrors for the repository we're going to update.

We used to recursively descend into the dependencies of the packages we
mark for install, this was needed so that we build all the packages we
want to.
However, the new package builder now does this for us. So simplify and
speed this up a bit by not doing it in apk.install().
Additionally, soft-remove support for passing in packages to delete by
having the package name start with a "!". This was useful at some point,
but we now handle this much better in pmaports.

Generalise pmb.helpers.other.cache with a more python decorator.
The Cache decorator takes a list of function arguments to use as cache
keys, keyword args can be used to restrict caching so that it is skipped
entirely unless the attribute has a specific value.
For example, pmb.helpers.pmaports.get() has the decorator:
@Cache("pkgname", subpackages=True)
This means the return value will be cached only when subpackages is
True, otherwise it will always miss.

We used to called pmb.chroot.shutdown() with "only_install_related=True"
here to unmount everything in the chroot so we could reliably "df" it to
figure out the rootfs image size.
Since ("pmb.chroot: only init once"), the chroot is no longer
automatically spun back up when we run mkinitfs, and the in-pmbootstrap
marker isn't recreated.
We only actually need to unmount the chroot anyway, so let's restrict it
to just that and remount things again afterwards.
This avoids weird side effects (like the native chroot being
shutdown?!), but this is something we should look into more in the
future since we're still doing a finnicky balancing act to manage chroot
state here.

Use the new config.mirrors section to handle repository URLs instead of

add the systemd staging repo automatically when on the systemd staging

Move pmb/parse/arch.py over to core and refactor it as an Arch type,
similar to how Chroot was done. Fix all the uses (that I can find) of
arch in the codebase that need adjusting.
The new Arch type is an Enum, making it clear what architectures can be
represented and making it much easier to reason about. Since we support
~5 (kinda) different representations of an Architecture (Alpine, Kernel,
target triple, platform, and QEMU), we now formalise that the Alpine
format is what we represent internally, with methods to convert to any
of the others as-needed.

Introduce a Deviceinfo class and use it rather than the dictionary. This

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).

Testing by building postmarketos-initramfs (which installs >100 packages
but is very fast to build, so a worst-case scenario) this results in a
~15-20% speedup (which everything cached and doing multiple back to back
runs). From 32 seconds down to 25.
Doing a full install with --no-image, this takes us from 70 seconds on
my laptop down to 40s!
This also lets us drastically simplify pmb/helpers/apk.py!

We currently lazily initialize the chroot's on first use, plus a few
bonus calls to init. However, there are some instances where we actually
don't want the chroot to be initialised (mostly to break recursion
loops).
Simplify the codebase by removing all of this, and just calling
pmb.chroot.init() where it's needed.
In addition, print a warning if init() is called multiple times for one
chroot. This should help us catch these instances if they crop up again.

We currently do stuff in the chroot before merging /usr, this could lead

We don't need to re-init the chroot this often, cache on first init and
skip all subsequent ones. Even though we take a shortcut if the chroot
already exists we still do a bunch of additional checks which we only
really need to do once.

This is multithreaded, and by consequence much much faster than default
gzip. Since we switched to running gzip from the native chroot we also
changed from running it in the fastest mode, now we're running it with

We use a custom verbose log level in pmbootstrap, unfortunately it isn't
possible to correctly type this due to some limitations in the logging
library [1], [2].
Given that our usecase is fairly simple, we can just wrap the module
with our own so we only have to tell mypy to ignore the error once
instead of at every callsite.

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.
It's nice to know how much space gets free'd when zapping, but I often
find myself with a lot of chroot's and other junk, and on my laptop
running "du" across all of this takes quite a few seconds. As this is
purely cosmetic, it doesn't justify taking such a long time.
Remove the size calculation code to substantially speed up zap.

This is needed to bring up the v24.06 repositories at
build.postmarketos.org. With the latest apk version, apk refuses to
operate if an URL from /etc/apk/repositories cannot be fetched.
Before the repositories are created for the first time, they do not
exist, so we will just set PMB_APK_FORCE_MISSING_REPOSITORIES=1 in bpo
to be not blocked here.
I've also spent significant time on alternative implementations, but
they have problems:
- Let bpo create an empty APKINDEX before building the first package,
but this was a larger code change, leading to lots of adjustments in
the tests, and ultimately it seems it didn't work properly (it seems
apk/abuild doesn't create a valid signed APKINDEX for one that has no
packages).
- Do not set the --mirror-pmOS argument for the "final" repository, only
the "wip" repository, until the "final" repository is available for
the first time. This works fine for x86_64, but not for foreign arch
repositories because then the cross compilers from the x86_64
repository are not available. I've also tried to make a different env
var that ensures we don't write the non-existing repository to
/etc/apk/repositories from within pmbootstrap if initializing a
foreign arch chroot, but then we would find a sane way to do this only
for the "final" repository and not for the "wip" repository which
leads to a lot more complexity than this patch.
So this is not the nicest solution (apk still tries to fetch the indexes
and gets a 404), but it is the simplest one and unblocks us from working
on v24.06. Also it doesn't add more complexity which is important in the
middle of the feature freeze we are currently in.
