The server side recently added support for tuning some magic
crush variables. Decode these variables if they are present, or use the
default values if they are not present.
Corresponds to ceph.git commit 89af369c25f274fe62ef730e5e8aad0c54f1e5a5.

These were used for the ill-fated forcefeed feature. Remove them.

Remove forcefeed functionality from CRUSH. This is an ugly misfeature that
is mostly useless and unused. Remove it.

Move various types from int -> __u32 (or similar), and add const as
appropriate.
This reflects changes that have been present in the userland implementation
for some time.

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.
