The following series of patches constitute a few minor
fixes and cleanups, as well as some new utility routines
in the rbd code. Some of these comprise a foundation
that's being used to add support for the "new" rbd image
format.
We've agreed to refer to the "old" and "new" formats as
format 1 and 2, respectively.

[PATCH 01/16] libceph: fix off-by-one bug in ceph_encode_filepath()
This is a minor bug fix.
[PATCH 02/16] rbd: drop a useless local variable
This is a minor cleanup.
[PATCH 03/16] libceph: define ceph_decode_string()
[PATCH 04/16] libceph: define ceph_extract_encoded_string()
[PATCH 05/16] rbd: define dup_token()
Each of these defines a new utility routine. They are
all going to be used in some upcoming rbd patches, but
they're ready for review now.
[PATCH 06/16] rbd: rename rbd_dev->block_name
[PATCH 07/16] rbd: dynamically allocate object prefix
These update the "block_name" field of a rbd_dev structure
to be named "object_prefix", which is consistent with the
way the new rbd format describes it. It also removes the
unnecessary fixed limit on the length of that string.
[PATCH 08/16] rbd: don't store pool name in struct rbd_dev
Since a pool name can change, this patch makes sure the
rbd client code doesn't save a copy of it--relying instead
on the invariant pool id. The "pool" entry has been
replaced by "pool_id" in /sys/bus/rbd/<N>.
[PATCH 09/16] rbd: dynamically allocate image header name
[PATCH 10/16] rbd: dynamically allocate image name
[PATCH 11/16] rbd: dynamically allocate snapshot name
These three change some more fields for in-core data
structures so they aren't arbitrarily limited to a fixed
size.
[PATCH 12/16] rbd: use rbd_dev consistently
This makes all variables representing a struct rbd_device
be named "rbd_dev".
[PATCH 13/16] rbd: rename some fields in struct rbd_dev
[PATCH 14/16] rbd: more symbol renames
[PATCH 15/16] rbd: option symbol renames
These change the names of some fields and symbols so
they are (hopefully) a bit more descriptive.
[PATCH 16/16] rbd: kill num_reply parameters
This eliminates an unused parameter that was defined in
a number of functions.
