- decode.h needs slab.h for kmalloc()
- osd_client.h needs msgpool.h for struct ceph_msgpool
- msgpool.h doesn't need messenger.h

Initialize the type field for messages in a msgpool. The caller was doing
this for osd ops, but not for the reply messages.

The pool allocation failures are masked by the pool; there is no need to
spam the console about them. (That's the whole point of having the pool
in the first place.)
Mark msg allocations whose failure is safely handled as such.

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.
