Add cancel backup capability.
This will stop the iteration of the partition objects, kill the
current twrpTar thread and remove the backup directory.
Implement TWAtomicInt class to give us a wrapper that automatically
uses mutexes before the read and write to help ensure that the
reads and writes will be atomic based on documentation.
