This adds implicit rollback support during A/B style updates.
If you explicitly start a checkpoint with -1, needsRollback will
trigger if the update fails, and should be used if any additional
cleanup is needed that is not covered by A/B itself.
Test: All Checkpoint tests pass

On userdebug protect /mnt/scratch. On user builds ensure that
/mnt/scratch is considered a stale mount so it can not be used.
vold runs before ro.debuggable is set, so this must be a compile
time decision.
Minor technical debt cleanup associated with using android::base.
Test: compile

When both VFAT and exFAT are supported VFAT will only be used to
format card. Use exFAT for cards larger than 32GB per SDXC standard.
Test: build, manual, mount exFAT volume

Helpers to get a block device size in bytes or 512 byte sectors,
using BLKGETSIZE64 and returning value of uint64_t type.
This also removes get_blkdev_size().

Checkpointing uses a combination of files on the meta partition
and the checkpoint= fs_mgr flag. Checkpointed partitions will
revert to their starting state on reboot unless checkpoint commit
is called.
Test: Run vdc commands, check file on metadata

This will allow adding lots of verbose logs which can be enabled
only during local testing/debugging. Update the existing verbose
level logs to debug level since we want those to be logged by
default.

When using make_f2fs to format a filesystem with quota enabled, make_f2fs
will write quota record with group id equtal to make_f2fs's execution
group id.
Vold shall run as root group so that make_f2fs forked by vold will enherit
vold's root group. Make_f2fs can then write quota record with group id for
root group and therefore kernel quota driver can find quota record for
root group.

Remove the Speck encryption support. It was eventually
decided not to allow Speck in Android P, so this code
is no longer needed and wasn't used outside of testing.
Note we don't just "git revert" the original commit
(38723f23ff) because we want
to retain the infrastructure for allowing new types of
crypto algorithms in the future.
Bug: 112009351
Test: Attempted to setup a device with ro.crypto.fde_algorithm set to Speck, and Speck was rejected and the system defaulted to AES.

This file should avoid F2FS GC, since it directly access block device based
on fibmap.
