This allows us to get rid of some of the validation in sanity_checks()
as mypy handles this validation at "build time", and any typos in the
enum instantiation would be a runtime error rather than a silent
failure.
Additionally, it allows us to encode some of the behaviour of the
different output types into the type definition itself by using methods.

Apparently python reads uname for this value, the correct value for
64-bit intel/amd stuff is `x86_64` even though python's docs list
`amd64` as an example of a value `platform.machine()` can return 🤷fixes#2612

We fully expect to reach this code path within normal use of
pmbootstrap. It's not a bug if we get here. As such, use NonBugError to
indicate that and clean up the output.
img_path_2nd is a Path, not a str, so we can't just rely on string
concatenation here.
img_path_2nd is a Path as that's what create_second_storage() returns
since 198f302a36.
Don't try and install random packages in the rootfs chroot when starting
QEMU. The chroot is not initialised and this just adds latency.

Add a new flag --image which can be used to mount the rootfs generated
with "pmbootstrap install".
For now this is quite limited in scope. But it's enough to allow for
building a package, updating it in the QEMU image, and then booting it.
The major "gotcha" with this is that the QEMU uses the kernel and
initramfs from the device chroot unless you run it with --efi.

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
gives us sweet sweet autocomplete, and lays the foundation for having a
proper deviceinfo validator in the future.
Additionally, continue refactoring out args...

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).

Defaulting to the native chroot isn't necessarily intuitive. Let's
require this be specified in full.

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.

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.

According to the type hints for os.cpu_count(), it might return None...
To be safe, add a warning and a fallback in this case (though it seems
incredibly unlikely this would ever be hit)

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.
Recent changes to qemu and Alpine packaging now require using the
virtio-vga-gl device and installing -gl packages to get virglrenderer
support.
Without this, wlroots fails to get an EGL context (among other problems
you'd expect by not having a useful GPU around...)

On qemu-system-riscv64 the -nic option doesn't seem to work correctly.
qemu-system-riscv64: warning: requested NIC (anonymous, model virtio-net-pci) was not created (not supported by this machine?)
Using -netdev and -device provides the same functionality and also works
on riscv64.
