CreateLogicalAndSnapshotPartition is used in first-stage init and by
default never blocks (thanks to a timeout set to 0). This causes some
libsnapshot tests to fail, because snapshot devices may be accessed
before there actual creation is complete.
Fix by introducing a timeout_ms argument, set to 0 if unspecified.

ACgroupController_getFlags was reverted due to LLNDK breakage, however
it allows detection of cgroups that failed to mount in a more efficient
way. Revive the function as a weakly linked symbol to allow for it to
be missing in case older LLNDK library is being used with the new
system software. This effectively reverts the commit
aa1d54f0cc "Remove ACgroupController_getFlags to fix API breakage"'
except it declares ACgroupController_getFlags function as weak and
targets it for API level 30. If LLNKD library does not contain
ACgroupController_getFlags the behavior falls back to the current
way of identifying cgroups that failed to mount.
Test: build and verify correct operation with a missing cgroup

In Android kernels >4.4 we will see an empty /sys/kernel/tracing
directory which is notionally where you should mount tracefs if you
don't want to mount debugfs. As we move towards not mounting debugfs,
ensure that the non-legacy location also has adequate permissions to be
read by tracing tools.
Note that this change will be OK even if the board init.rc doesn't mount
tracefs here, because sysfs will always create this directory.

Currently, this is only enabled for Virtual A/B devices. When /data uses
F2FS, then proper pinning support must be enabled.
Because /data cannot be mounted in recovery, we can't delete the scratch
image backed by /data while in fastbootd. Instead, we mark it as
disabled in /metadata. The remount command now has an init script that
checks for and removes a disabled scratch partition.

Currently when vendor overrides a profile the profile object is being
replaced with a new one. However the old profile might have been
referenced by an aggregate profile and with such profile replacement
the aggregate profile is left referencing a stale object. Fix this by
replacing the content of the old profile with the content from the new
one instead of replacing the object itself.

In the current state, schedboost_enabled() is true if and only if
schedtune is in use. As a result, all tests conditioned by
schedboost_enabled() will be skipped on devices using uclamp since it is
and extension of the CPU controller.
Fix this by making schedboost_enabled() return true if either schedtune
or the CPU controller is enabled.

When using partitions backed by /data, for example during a Virtual A/B
merge or "adb remount" on a Virtual A/B device, the userdata block
device is seen as in-use when /data mounts in second-stage init. This
subsequently prevents mount() or e2fsck from working. Metadata-encrypted
devices are not affected, because dm-default-key provides a wrapping
block device that can be used exclusively.
This patch addresses the problem by detecting when userdata has
device-mapper dependencies. If it does, and the device is not
metadata-encrypted, we introduce a dm-linear wrapper around userdata.
It is created on demand, but like logical partitions, it exists until
the device reboots.

To allow apps with MANAGE_EXTERNAL_STORAGE permission and therefore
external_storage gid to access unreliable volumes directly on
/mnt/media_rw/<volume>, they need access to the /mnt/media_rw path.
This change doesn't break the FUSE daemon, the only process that should
have media_rw gid in R because the FUSE daemon accesses the lower
filesystem from the pass_through bind mounts of the public volume mount
itself so it doesn't need to walk the /mnt/media_rw path itself
Test: With FUSE enabled, a reliably mounted public volume is accessible
on /storage

The memcpy should be for 31 GPRs, [x0, x30]. Currently it (accidentally)
also copies over the SP register (which ends up being harmless, as the
layouts match, and the value is reassigned again anyway).
Separately, I'm including an optional change for the iteration order,
since LR is the x30 GPR, it makes slightly more sense to print it
immediately after x29. However, this is a change in behaviour, so I can
undo the change if you think it's not worth it.

This gid allows processes full access to public areas of external
storage. This includes the following:
1. EmulatedVolumes: All files and directories excluding the app
specific directories under Android/
2. PublicVolumes: Including 'unreliable' volumes (USB OTG) that are
not typically accesible to ordinary apps
Apps with the MANAGE_EXTERNAL_STORAGE permission will automatically
have this gid
