time_started in encryptGroupsData is set from and compared to
clock_gettime(CLOCK_MONOTONIC, ...) nearly everywhere: "Clock that
cannot be set and represents monotonic time since some unspecified
starting point". However in cryptfs_enable_inplace_f2fs() it is set
from a different clock, time(NULL), with the result that the setprop
calls that indicate progress are wrong and can be called much too
often. The fix is to make this function consistent with
cryptfs_enable_inplace_ext4.

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.

We rename our 'buf' in the inner scope to avoid confusion with
the 'buf' in the outer scope which is used immediately after
exiting the inner scope.

This will allow adding lots of verbose logs which can be enabled
only during local testing/debugging. Update the existing verbose
level logs to debug level since we want those to be logged by
default.

Don't use the FDE flow to support metadata encryption; just provide a
vold service which directly mounts the volume and use that.

Test: Boot Taimen to SUW with and without metadata encryption.
