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.

Test: touch /metadata/tradeinmode/wipe && adb reboot

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.

In a GRF config, if Vendor partition is updated from Android 12; post
OTA reboot, first stage init will communicate to daemon to check if the
daemon can support socket handoff. If that succeeds, then it is a signal
that the vendor has been updated from Android 12. Use a marker in
/metadata to signal that the vendor was updated. If the marker is present,
then post OTA reboot, userspace snapshot will be used.

Targets like PCs/VMs usually don't have fixed boot devices.
For example, moving the disk to another controller would result
in getting different block device path.
To workaround this situation, add an option to bypass the boot
device filter, so that every block devices would get their
symlink in /dev/block/by-name/.
Usage: Specify `androidboot.boot_devices=any` on bootconfig or cmdline
Test: /dev/block/by-name/* exists when `androidboot.boot_devices=any`

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.

ro.boot.hardware.cpu.pagesize is used on some devices to
report the page size. However, we also know what value this
should be from the CPU. Rather than create a separate property
for this, standardize around this property.

devices.
