There were several problems here:
1- we weren't tagging allocations with the pool, so they were never
returned to the pool.
2- msgpool_put didn't add back to the mempool, even it were called.
3- msgpool_release didn't clear the pool pointer, so it would have looped
had #1 not been broken.
These may or may not have been responsible for #1136 or #1381 (BUG due to
non-empty mempool on umount). I can't seem to trigger the crash now using
the method I was using before.

This factors out protocol and low-level storage parts of ceph into a
separate libceph module living in net/ceph and include/linux/ceph. This
is mostly a matter of moving files around. However, a few key pieces
of the interface change as well:
- ceph_client becomes ceph_fs_client and ceph_client, where the latter
captures the mon and osd clients, and the fs_client gets the mds client
and file system specific pieces.
- Mount option parsing and debugfs setup is correspondingly broken into
two pieces.
- The mon client gets a generic handler callback for otherwise unknown
messages (mds map, in this case).
- The basic supported/required feature bits can be expanded (and are by
ceph_fs_client).
No functional change, aside from some subtle error handling cases that got
cleaned up in the refactoring process.
