Drop the console-shell hook in favour of stuffing buffyboard into the
initramfs. This makes it possible to get a debug shell directly on the
device without needing to use a computer.

mdev is slow and missing features, it also requires that we load all the
modules that we include at once making the boot process slower.
udev is required for unl0kr (and buffyboard), it can also load modules
on demand (and asynchronously). Making the boot process considerably
faster on devices, especially for generic images where we have lots of
drivers for different display panels in the initramfs.
Additionally, import full fat modprobe from the kmod package, this is
required to support compressed modules.
This brings us more in line with other distros and generally improves
compatibility.
If devices use broken kernel modules which don't correctly define
modalias', these drivers may not be loaded by udev. This should be fixed
by defining the missing modalias statements in the driver.
This also runs udev earlier in the init, so that display drivers are
loaded before the splash in case they are needed.

This incorprates the debug-shell functionality directly into the
initramfs, so it's no longer necessary to build and boot a custom
initramfs in order to debug your device.
Additionally, the behaviour of the debug-shell is entirely reworked, It
now creates an ACM serial gadget which can be accessed via any normal
terminal emulator (picocom, minicom, etc; or PuTTY on windows). Rather
than just invoking sh, the debug-shell now creates a respawning getty on
both the new virtual console and the active console (this will either be
the UART console or tty0/1).
It is necessary to spawn these shells via getty since the logging rework
means we can no longer assume that stdin/out/err reference a TTY.
In addition to the above, it is now possible to trigger a log dump by
holding volume up during boot. This can be useful for helping users
debug their devices if the issue doesn't result in a failure that can be
detected in the initramfs.
With these changes, the console-shell and debug-shell hook packages are
reduced to only adding the additional tools/features. console-shell is
still required for fbkeyboard, and debug-shell for the setup_usb_storage
tool.

Drop in mdev.conf and the /lib/mdev/persistent-storage script, these
cause /dev/disk/by-* to be populated in the ramdisk, making it
possible to do look up partition by-label and by-partlabel for free,
compared to findfs which can take some time.
As a first optimisation based on this, check for some partitions using
these paths and prioritise them when looking for subpartitions. Drop the
first find_boot_partition call as it doesn't really save time over the
call in the while loop.
The mdev config also handles setting up /dev/null, /dev/random, etc, so
these don't have to be done manually.
These files aren't owned by mkinitfs, or used to configure mkinitfs, so
I think it makes sense that they belong in a dir specific to this
package instead of cluttering up mkinitfs's config dirs.
This appears to be an ancient leftover from the telnet-based FDE
unlocking mechanism that has been present many many years ago.
But since this was removed a while ago, it's time to also finally remove
telnetd from the initramfs.
This package contains base file and module lists for the initramfs /
initramfs-extra archives, along with the init.sh
The primary reason for doing this is so that changes to these
files/lists can be properly versioned (in pkgver), and (re)building
mkinitfs itself is no longer required for these changes.
- Add base file list for initramfs. The dirs at path
/usr/share/postmarketos-mkinitfs/* are "new" in mkinitfs 2.0
- Install default modules to /usr/share
- Install system config to /usr/share/mkinifs
- Add base files for -extra archive
- Create user config dirs
- Update hook dirs in init.sh, change from mkinitfs 2.0
- Remove splash images, obsolete since pbsplash
- Support uncompressed initramfs-extra
