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

With this option the fstab can include a parameter for zram
the enables more streams for kernels that does not have
dynamic stream task handling.
Test: Made sure max_comp_streams is set according to fstab.

Pointer from strdup is lost hence triggers mem leak warning from
clang, since ptr returned from basename may not point to start of
duplicated string any more.
Switch to use gnu version of basename which doesn't modify input
string so that strdup is no longer necessary.

Right now these two partitions are mounted in the fs stage of the init
process. As a result, many vendor/ODM files needed earlier in the boot
process (e.g., init.<hardware>.rc, fstab.<hardware>.rc,
uevent.<hardware>.rc, SELinux policy files etc) can only live on the root
partition.
To prevent vendors/ODMs from polluting the root partition, this patch makes
it possible to mount the vendor and ODM partitions in the first stage of the
init process. The fstab info of both partitions to be mounted early is
composed from new kernel cmdline arguments android.early.prefix and
android.early.fstab.
For example, with:
android.early.prefix=/sys/devices/1010000.msdc0/mmc_host/mmc0/mmc0:0001/block/mmcblk0/
android.early.fstab=mmcblk0p10+/odm+ext4+ro+verify\nmmcblk0p09+/vendor+ext4+ro+verify
the final fstab string will be:
/sys/devices/1010000.msdc0/mmc_host/mmc0/mmc0:0001/block/mmcblk0/mmcblk0p10 /odm ext4 ro verify
/sys/devices/1010000.msdc0/mmc_host/mmc0/mmc0:0001/block/mmcblk0/mmcblk0p09 /vendor ext4 ro verify
The android.early.prefix is optional. When it is missing, the final fstab
string will be directly converted from android.early.fstab.
This patch also makes sure that the early mounted partitions are dm-verity
enabled so that they are trust worthy to store system files.

Use the correct device name when system is mounted as root, and
validate dm-verity status to avoid confusing it with dm-linear.
