b180b6ce19 mds: clean out old revocation history on racing release 
If a release and revoke are racing, we need to make sure the MDS
behaves even though the revoke msg will be ignored.  For example:

mds                    client
1 pAs                  pAs
                       release(last_issue 1)
2 p                    p (*** ignored ***)
3 pAs (issue)          pAs
4 p                    p
5 pXs (issue)          pXs
release(last_issue 1)  *** (was completely) ignored ***

We fix this by including both seq AND last_issue in revoke_info.
The cap state for the above is thus:

mds cap state:
 last_issue = 5
 _pending = pXs
 _revokes = [ p seq=2 li=1, p seq=4 li=3 ]

and the MDS will trim any old revokes for which li <= its
last_issue.  For anything after that, the client will have seen a
new issue and will have stopped ignoring cap messages.

d149c7e7ec mds: do not save cap_push_seq on disk [disk format change] 
The cap_push_seq is purely associated with the current instance
of the session.  On MDS restart and client reconnect, it resets
to zero.  Don't save it.

f155bd8c53 kclient: stop using msgpools for incoming msgs 
Even though we may only dispatch N messages at a time (if we
have N cores), we may have many more connections, and be
reading the same message types in parallel from multiple
peers.  Msgpool_alloc blocks when teh pool is empty, which
will make the messenger thread hang, and stall forward.

Badness.

There is no easy solution here.

c55f2e9812 mds: clean up loner set/drop logic 
Track what loner we _want_ separately from what loner we have, so
that locks can move toward the right state.

Centralize loner set/drop call points.

Move out of EXCL in simple_eval if our target loner is -1(none).

0266f877ad kclient: don't keep reply ref in osd_request; just parse out the result 
This requires a few new flags: r_prepared_pages, so we only do that
once, and r_got_reply, so we only parse the result once.
