To support upcoming disk usage calculation optimizations, this change
adds a new 'quota' mount flag. As part of mounting an ext4 device,
we now enable/disable the quota feature using tune2fs to match the
requested value in the fstab.
When changing the quota status, we force a fsck pass on the device
before actually mounting it to prime the quota data structures which
are stored in hidden inodes.
Changing quota state and priming the data structures needs to happen
before we actually mount the device, so fs_mgr is the best place to
place this logic.
Test: builds, boots, enables and disables quota

>3 times faster access for lookup functions. Code simplification and
C++ coding style conversion. android_lookupEventTagNum has been
expanded to utilize the Format match, and then drops down to just
Tag match.
Performance testing on Hikey, all services stopped, shell only access,
CPU not locked had good repeatability.

This is a cherry-pick of internal commit:
f611291688 which was a revert of a
revert, specifically a revert of commit:
c8f026fc9c.
The above revert was meant only for AOSP, since the kernel prebuilts
were not yet available there. The revert was reverted internally so
that internal builds, which have the appropriate kernel prebuilts,
operated properly.
The very first commit was originally done in nougat-dev and cherry-picked
to AOSP, so it was not picked up again when nougat landed in master. Add
it now.

To support upcoming disk usage calculation optimizations, this change
creates a new GID for each app that will be used to mark its cached
data. We're allocating these unique GIDs so that we can use
quotactl() to track cached data on a per-app basis.
This change also tightens up the implementation of both the cache
and shared GID calculation to ensure that they stay inside the valid
ranges, and includes tests to verify.
Test: builds, boots, tests pass

We do a remote stat to get the file's size before pulling in sync_recv,
but all of the callers to sync_recv have already done a stat. Pass the
