When both ext4 user data checkpoints and metadata encryption are
enabled, we are creating two stacked dm devices. This had not been
properly thought through or debugged.
Test: Enable metadata encryption on taimen (add
keydirectory=/metadata/vold/metadata_encryption to flags for userdata in
fstab.hardware)
Unfortunately metadata is not wiped by fastboot -w, so it is
necessary to rm metadata/vold -rf whenever you wipe data.
fastboot flashall -w works
fastboot reboot -w works
A normal boot works
Disable checkpoint commits with
setprop persist.vold.dont_commit_checkpoint 1
vdc checkpoint startCheckpoint 10
adb reboot
wait for device to fully boot then
adb reboot
Wait for device to fully boot then
adb logcat -d | grep Checkpoint shows the rollback in the logs
This tests encryption on top of checkpoints with commit, encryption
without checkpoints, and rollback, which seems to be the key cases.

abortChanges will attempt to pass a reboot message, and will only reboot
if the device is currently checkpointing. Additionally, it can opt to
attempt to prevent future attempts. This only works for non-bootloader
controlled updates. Failures are ignored, as it will always reboot the
device. In the unlikely event of such a failure, the device will
continue to retry as though you did not ask to prevent future attempts.

We support file-based encryption on both ext4 and f2fs now, and the
kernel API is the same. So rename things appropriately in vold:
e4crypt => fscrypt
ext4enc => fscrypt
Ext4Crypt => FsCrypt
EXT4_* => FS_*
ext4_encryption_key => fscrypt_key
Additionally, the common functions shared by 'vold' and 'init' are now
in libfscrypt rather than ext4_utils. So update vold to link to
libfscrypt and include the renamed headers.
Note: there's a chance of 'fscrypt' being confused with the dm-crypt
based encryption code in vold which is called 'cryptfs'. However,
fscrypt is the name used in the kernel for ext4/f2fs/ubifs encryption,
and it's preferable to use the same name in userspace.
Test: built, booted device with f2fs encryption

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.

- Also update vold to create sandboxes for secondary storage devices.
- Since bind mounts are created in the process specific namespaces, we
don't need /mnt/storage anymore which we were using it to prevent
some bind mounts from propagating onto /mnt/runtime/write.
- Create bind mounts for {media,obb} dirs similar to data dir in
per process namespace.
- Also fix a bug where we are not passing correct packages to vold when
a new user starts.
