When using "adb remount" on a deduplicated filesystem, the current
response is a warning that the remount will not work. This patch
allows the user to specify an -R option. This option will reboot to recovery,
run e2fsck to undo deduplication, and then reboot the device where "adb
remount" will then succeed.
In addition, if verity needs to be disabled to remount, it will be disabled in
the same reboot cycle to minimize reboots.

A deduplicated filesystem might not have enough free space to undo its
block sharing. In this case "adb remount" should give a more precise
error message.

If BOARD_EXT4_SHARE_DUP_BLOCKS is true, "adb remount" will error saying
the filesystem is read-only. Instead, it will now list affected
partitions and explain why they can't be remounted.

Rearrange some files while we're doing this.
