By moving FindDmDevice() it's easier to unify the code with the
IsBootDevice() function. In this case the order doesn't matter since
anything with the uevent path "/devices/virtual/block/dm-" (the only
devices FindDmDevice() looks at) won't match any of the other sections
of the if/then/else test.

As of commit upstream Linux kernel commit 74f4a8dc0dd8 ("block: add
partition uuid into uevent as "PARTUUID""), it's easy to include the
partition UUID in the Uevent structure. Add it in so that other parts
of the init code can make decisions based on the partition UUID.
If this code is run on older kernels we'll never see the partition
UUID and it will be left blank.
Bug: 316324155
Test: Run w/ a newer kernel and see partition_uuid populated.

This reverts commit 5bfb93678f.
Reason for revert: b/376468452 and trusty boot up on arm64. This CL is causing a lot of troubles (now only on emulator, but may affect more devices in field) and shall be reverted. Desktop team will handle support for selecting single boot source (while having more than one) as part of boot_part_uuid support (at aosp/3318438).

As a preparation for upcoming commit, extract part which is responsible
for external program execution to libmodprobe so it can be later
re-used not only for firmware handler but also for dynamic module
options handler within libmodprobe.
RunExternalHandler is moved entirely to separate library with two
changes:
- Setting env needed previously by firmware handler was made generic and
now external handler can get envs_map containing pairs of env and its
value which needs to be set.
- "Firmware" was removed from one of the log since now it can be used in
different context (s/External Firmware Handler/External Handler/)

When adding a dependencies, if the variants don't match, but the
dependency only has 1 variant anyways, soong will always use that
variant. This makes it hard to add new variants to soong, because the
1-variant fallback stops being used and you start getting missing
variant errors. Make changes to bp files such that all dependencies
correctly specify the variant to use.

Schedtune was an out of tree cgroup controller present in Android
kernels up to 4.19. It was replaced with uclamp and the cpu controller.
Now that 4.19 is EOL and unsupported, and schedtune is not present in
any supported Android kernels, remove the userspace support for
schedtune.

The cgroup.rc file was introduced in 192aee782 ("libprocessgroup: Add
support for task profiles") back with the initial support for task
profiles. It was intended to optimize performance associated with cgroup
operations. However over time, supporting this file led to making
libprocessgroup code more complicated (such as the cgrouprc LLNDK
interface), and the file ended up getting mmaped into nearly every
process on Android even though only a handful of them actually use it.
Replacing this file with reading and parsing of cgroup information on
demand allows us to simplify and shrink libprocessgroup, and eliminates
thousands of unused mappings without negatively affecting boot time or
other performance metrics.

This modifies first-stage init to check for /metadata/tradeinmode/wipe
as soon as /metadata is mounted. If the file exists, we issue a request
to the bootloader to reboot to recovery and wipe /data. Since this also
wipes /metadata, the wipe indicator will be removed too.
In case some kind of failure happens in recovery, this also implements a
quick-and-dirty counter mechanism to fallback to the recovery menu.

Init code is bailing out as soon as `super` partition was
found in the system, ignoring rest of uevents.
In case given device contains multiple boot sources, `super`
partition as well as all other partitions shall be taken
from the same boot source, instead of relying on
`which uevent came first`.

In this change we're moving the asynchronous netd startup ahead of
the async statd and *synchronous* update_verifier.
This is desirable as we want a netd failure (which could
happen due to some mainline incompatibility wrt. bpf
or mainline shipped shared libs: resolver or netd updatable)
to be considered a signal for a bad boot.
It's still asynchronous though, so it's not ideal.

snapshot metadata files are stored in /metadata. This means, we cannot
wipe after installing any update.
This patch does the following:
1: Create a scratch space in super partition. The scratch space for ota
metadata is just about 1MB.
2: Create ext4 filesystem on top of scratch block device.
3: Mount the scratch on /mnt/scratch_super
4: When snapshot-manager instance is created, point the /mnt/scratch/ota
to metadata_dir_ so that all the snapshot files are stored in the new
path.
All the logic of OTA remains the same. This flow is enabled only on userdebug builds for now and the only consumer would be snapshotctl
$snapshotctl apply-update /data/nbd/ -w
During init, we would have to mount the scratch partition to detect
if there is any pending updates.
With this, we would now be able to wipe the device along with the update flow. This will help incremental flashing wherein we would end up saving ~35-40 seconds on Pixel devices.
With this flow, the end-to-end update for incremental builds takes
~20-30 seconds.
