In case of userspace reboot, this function will be called again to
remount userdata into checkpoint mode.
Test: adb shell setprop sys.init.userdata_remount.force_umount_f2fs 1
Test: adb shell /system/bin/vdc checkpoint startCheckpoint 1
Test: adb reboot userspace

This creates apexrollback directories under /data/misc_[de|ce]/<user>
which will hold snapshots of DE_n and CE_n apex data directories
(i.e. it will hold backups of data from /data/misc_[de|ce]/<user>/apexdata
for particular apexes).
See go/apex-data-directories for details.

It will be used during the userspace reboot to unmount all emulated
storages, which is a prerequisite to unmount+remount ext4 userdata into
checkpoint mode.

This creates an apexdata directory under /data/misc_de/<user> and
/data/misc_ce/<user>, and also creates a directory under that for
every APEX that is installed.
See go/apex-data-directories.
APEXes are discovered by scanning the /apex directory. It may be better
to delegate this process to a library, but it is proposed to defer that
change to a future CL.

The HidlizationEquivalenceTest was used to make sure the same key is
computed by the scrypt algorithm regardless of whether the old
(<= KM2 HAL pre treble) or the new (>= KM3.0 treble) HAL was used.
Since the treble is now the default, and old HAL don't even exist on
new devices, we should call the migration a success and drop this test
altogether.
Test: Removed obsolete Code

The property is set to inform kernel to do a warm_reset on the next
reboot. This is useful to persist the logs to debug device boot
failures. After the slot has been marked as boot successful, we can drop
the warm_reset flag to avoid the performance overhead on the next
reboot.

Test: check the property is set to 0 by vold

Now that we include libfscrypt in libfs_mgr via whole_static_libs we
should not reference it directly.

It will be used by userspace reboot to reset checkpoint state, to make
sure that when /data is remounted, it will be remounted in checkpointing
if a checkpoint was requested beforee userspace reboot.
Test: /system/bin/vdc startCheckpoint 1
/system/bin/vdc needsCheckpoint (returns 0)
/system/bin/vdc resetCheckpoint
/system/bin/vdc needsCheckpoint (returns 1)
