btrfs-progs: Add delayed refs infrastructure
This commit pulls those portions of the kernel implementation of
delayed refs which are necessary to have them working in user-space.
I've done the following modifications:
1. Replaced all kmem_cache_alloc calls to kmalloc.
2. Removed all locking-related code, since we are single threaded in
userspace.
3. Removed code which deals with data refs - delayed refs in user space
are going to be used only for cowonly trees.
