We didn't calculate the user manifest's object etag at all. The etag
needs to be the md5 of the contantenation of all the parts' etags.

encoding: make .size() to __u32 cast explicit
Caught by clang warning that this is a conversion
from "unsigned long" to "unsigned int" which can
lose precision. However, this is the conversion
we want because our serialization format defines

mds: properly wake up dentry waiters after fragmenting dirfrag
When active MDS wants to fragment a replica dirfrag, it should set
the 'replay' parameter of MDCache::adjust_dir_fragments() to false.
It makes sure that CDir::merge/split wake up any dentry waiter.

a C++ static library, requires C++ linking. The rbd_operations
framework can be extended in the future to also test rbd_fuse.

Merge pull request #1532 from ceph/wip-fast-dispatch
fast dispatch
This series adds an ms_fast_dispatch interface to the Messenger/Dispatcher, designed so that you can dispatch messages directly from the Pipe threads without going through the Dispatch queue.
It also sets the OSD to make use of this interface for most operations, and switches to finer-grained locking and use of local data in a bunch of different paths to enable that.

mds: allow negetive rstat
When splitting dirfrag, delta rstat is always added to the first new
dirfrag. Ancestors of the dirfrag may have nagtive rstat before the
delta rstat has been propagated to them. For example:
inode 100 n(v1 b-4096)
|- dir 100 n(v1 b-4096)
|- dentry
|- inode 101 n(v1 b-4096)
|- dir 101.0* n(v1)/n(v1 b-4096)
|- dir 101.1* n(v1)
mds: fix frozen inode check in MDCache::handle_discover()
When MDCache::handle_discover() encounters a frozen dirfrag, it should
proceed if the dirfrag is being merged, but the MDS hasn't frozen all
dirfrags yet. When MDCache::handle_discover() checks if a inode is
frozen, it should use CInode::is_frozen_inode() (which doesn't check if
inode's parent dirfrag is frozen).
mds: include authpinned objects in remote authpin request
Server::handle_slave_auth_pin() may drop old authpins if it encounters
object that is not authpinable. So it is better to include objects that
have already been authpinned in the remote authpin reuqest.
