While I had the chance, I compared the rbtre code in btrfs-progs to that of
the latest kernel. No new bug fixes need importing, however rbtree.h and
rbtree_augmented.h get documentation updates

While debugging a broken fs we were seeing hangs in the rb_erase loops. The
rbtree was simple and wasn't corrupted so it appeared to be a bug in our rbtree
library. Updating to the kernels latest rbtree code made the infinite loop go
away, so pull it back. Thanks,
