doc: update instructions for RPM distros
Fix RPM building instructions: this has been broken since
libs3 was included inline in the ceph repo as a submodule.
"rpmbuild -tb" was concatenating the ceph.spec and
libs3.spec files, resulting in something that didn't work.
Also, the instructions suggested downloading a .tar.gz file
whereas the specfile requires a .tar.bz2 file.
Also, add a convenient yum command line for getting the compile
dependencies on Fedora 20.

If a client is sending a sequence of ops (say, a, b, c, d) and partway

come back completely out of order.

are no worse off than before.

osd: handle race between osdmap and prepare_to_stop
If we get a MOSDMarkMeDown message and set service.state == STOPPING, we
kick the prepare_to_stop() thread. Normally, it will wake up and then
set osd.state == STOPPING, and when we process the map message next we
will not warn. However, if dispatch() takes the lock instead and processes
the map, it will fail the preparing_to_stop check and issue a spurious
warning.

osd/ReplicatedPG: carry CopyOpRef in copy_from completion
There is a race with copy_from cancellation. The internal Objecter
completion decodes a bunch of data and copies it into pointers provided
when the op is queued. When we cancel, we need to ensure that we can cope
until control passes back to our provided completion.
Once we *do* get into the (ReplicatedPG) callbacks, we will bail out
because the tid in the CopyOp or FlushOp no longer matches.
Fix this by carrying a ref to keep the copy-from targets alive, and
clearing out the tids that we cancel.
Note that previously, the trigger for this was that the tid changes when
we handle a redirect, which made the op_cancel() call fail. With the
coming Objecter changes, this will no longer be the case. However, there
are also locking and threading changes that will make cancellation racy,
so we will not be able to rely on it always preventing the callback.
Either way, this will avoid the problem.
