The 'swap' is too generic and clashes with some userspace tools that
compile against btrfs, eg. snapper when including
boost::smart_ptr::scoped_array after kerncompat.h:
/usr/include/boost/smart_ptr/scoped_array.hpp:127:13: error: macro "swap" requires 2 arguments, but only 1 given
a.swap(b);

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.
