In version 2 of block image diffs, we support a new command to load
data from the image and store it in the "stash table" and then
subsequently use entries in the stash table to fill in missing bits of
source data we're not allowed to read when doing move/bsdiff/imgdiff
commands.
This leads to smaller update packages because we can break cycles in
the ordering of how pieces are updated by storing data away and using
it later, rather than not using the data as input to the patch system
at all. This comes at the cost of the RAM or scratch disk needed to
store the data.
The implementation is backwards compatible; it can still handle the
existing version 1 of the transfer file format.

Always create the block map for packages on /data; don't only look at
the encryptable/encrypted flags.

Do some error checking of lstat calls and better handle those
errors.
Use lstat instead of dirent to check if an item is a directory
because dirent does not return the correct item type when using
exfat-fuse.

Otherwise, overflow problems can occur with images larger than
2G since the offsets will overflow a 32-bit off_t.

Via command line in TWRP:
twrp set tw_mtp_debug 1
This will enable debugging for MTP. You will need to disable and
re-enable MTP in order to see the debug logging.

If busybox has SELinux support, we don't need toolbox to provide SELinux
specific tools. Check busybox for restorecon to see if SELinux support
is present and then adjust the tools built by toolbox based on this.

Enable TWRP to reside alongside other recoveries with the naming
convention: bootable/recovery(-flag). If TWRP resides at
bootable/recovery and a device does not specify RECOVERY_VARIANT, then
it will build like normal. If TWRP resides at bootable/recovery-twrp,
then its makefiles will only be parsed if a device specifies
'RECOVERY_VARIANT := twrp'. This prevents TWRP specific makefile
warnings/errors (notably, missing DEVICE_RESOLUTION) when another
recovery is being built.

Opening the misc block device in read-write mode runs afoul of
SELinux, which keeps the wipe code from working. Fix. Also change
various things to log to logcat so we can see them happening, for
future debugging.
