b67708361f vold: remove unused code for CONFIG_HW_DISK_ENCRYPTION
Nothing defines CONFIG_HW_DISK_ENCRYPTION, so remove the unused code
that's conditional on it being defined.

4ac43f0e16 EncryptInPlace: ensure that backup superblocks get encrypted
Block groups with EXT4_BG_BLOCK_UNINIT still have backup superblocks
(and backup block group descriptors).  Fix EncryptInPlace to encrypt
these backup superblocks rather than leave them unencrypted.

Previously leaving the backup superblocks unencrypted didn't cause any
problems, but due to system/core commit 72abd7b246f7 ("Try to recover
corrupted ext4 /data with backup superblock") it is causing problems.

1740effeaa Consistently use CLOCK_MONOTONIC for timing encryption
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.

236e5e800e Make ext4 userdata checkpoints work with metadata encryption
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.

e0691cc674 EncryptInplace: Rename variable
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.

4b6ca4ea65 Update vold to log only debug or higher level messages.
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.

Test: manual

0fd2626fc3 Add a mount with metadata encryption service
Don't use the FDE flow to support metadata encryption; just provide a
vold service which directly mounts the volume and use that.
