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.
Also ran same tests on unmodified Taimen and Blueline

Old approach (do not start class main) does not work because when
testings userdebug GSI on user system, adb does not start until the
framework starts.
