mds: use mds_stamp for mksnap
Use the server timestamp for the snapshot timestamp. This could arguably
be the client timestamp, but I think snapshot creation times are a bit
more important to have accurate timestamps on, and this should not be
something that existing client apps will strongly depend on.

mds: reset mds_stamp for readdir, rename, link
These ops to complicated work prior to starting the real operation, like
fetching missing directories, or opening remote dirfrags, creating
snaprealms. Reset the mds timestamp after this slow work has completed.

mds: use client-provided time stamp for user-visible file metadata
Use the op_stamp from the MDRequest, populated by the MClientRequest when
possible, for setting timestamps on user-visible metadata (like ctime,
mtime).

mds: do rstat timestamps (rctime, fragstat mtime) in terms of op stamp
Use the op (client) timestamp for the recursive stats, for santity's sake.
Note that since this is monotonically increasing, the danger here is
that we lose track of nested changes due to skewed client clocks.

This is a catch-all that we are carrying over from before. It may not
be strictly necessary, but I'm not inclined to check the code for
Mutation users who didn't call acquire_locks().

OSD: fix an osdmap_subscribe interface misuse
When calling osdmap_subscribe, you have to pass an epoch newer than the
current map's. _maybe_boot() was not doing this correctly -- we would
fail a check for being *in* the monitor's existing map range, and then
pass along the map prior to the monitor's range. But if we were exactly
one behind, that value would be our current epoch, and the request would
get dropped. So instead, make sure we are not *in contact* with the monitor's
existing map range.

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.

prioritise use of `javac` executable (gcj provides it through alternatives).
On Debian this fixes FTBFS when gcj-jdk and openjdk-7-jdk are installed at

calling GCJ when it is present.
