This fully enables metadata encryption on db845c by following
the instructions here:
https://source.android.com/security/encryption/metadata?hl=en
Mostly just adding --early/--late mountall arguments in the
init.rc and the "latemount" and
"keydirectory=/metadata/vold/metadata_encryption" options to the
userdata fstab line.
Note: You will likely need to flash new userdata (and possibly
reflash metadata as well) after applying this. Use the flashall
script if you are having any trouble.

remount overlay persistence issues
PeterC reported adb remount was not working properly,
and I noticed we had the same issue on HiKey960 recently
due to metadata not being set as first_stage_mount in fstab.
So this patch makes a similar change to fix the issue here.

This reverts commit 70f37c65199443d2502da58ecb81a4be28d36d80.
With Virtual A/B, we no longer need cache partition
for "adb remount" to work with overlayfs.

Now that sdcardfs is deprecated, we need a few tweaks to
support emulated storage on the board.
Thanks so much to Martijn Coenen and Daniel Rosenberg for
their help narrowing down the changes needed here.

The overlayfs remount handling of superpartitions expects the
fstab to have all the partitions in it.
This means we can't use the split between the ramdisk fstab
and the vendor fstab that we have been previously.
So this patch merges the two fstabs together.
With this change "adb root; adb remount" works now.

Add logic to support cache partition, as it seems
to be required to properly handle overlayfs remounts
on the super paritition.

If one runs "fastboot erase userdata", and then does not flash
a userdata image to the partition, the system will fail to boot
as /data/ will not mount, and the apex and dalvik cache
directories won't be present or writable.
This tries to address this by adding the formattable flag to
the fstab and add the partition to the sepolicy so mkfs can
access it.
NOTE: I did have to use the full by-name path in the fstab,
which is less flexible then the LABEL= method, but if the
partition isn't formatted there isn't neceessarily a partition
label to find.
Big thanks to AmitP for suggesting this approach
