7c0df05407 mds: do not reset filelock state when checking max_size during recovery 
This was broken by d5574993 (probably, that commit fixed a similar
problem).  The rejoin_ack initializes replica state properly, so we can't
go changing it now.  I'm not sure why this was resetting the state to
LOCK, because that's clearly not allowed.

Print when check_max_size does a no-op so that this is a bit easier to see
next time.

15c6651ff5 mds: lock->sync replica state is lock, not sync 
It's not readable yet.  And after the lock->sync gather completes we send
out a SYNC.

9248cd9e64 mds: don't change lock states on replicated inode 
The reconnect will infer some client caps, which will affect what lock
states we want.  If we're not replicated, fine, just pick something good.
Otherwise, try_eval() and go through the proper channels.

This _might_ be the source of #165...

c4bbb0008b mds: discover snapped paths on retried ops 
This is intended to mitigate a livelock issue with traversing to snapped
metadata.  The client specifies all snap requests relative to a non-snap
inode.  The traversal through the snapped portion of the namespace will
normally happen on the auth node, but the actual target may be on another
node that does not have that portion of the namespace.  To avoid indefinite
request ping-pong, the mds will begin to discover and replicate the snapped
path components if the request has been retried.

This doesn't perform optimally, but it will at least work.

a1c99811ba paxos: use helper to store committed state; fix master mon catch up using stash 
The catch up logic in handle_last didn't handle the stashed state, so we
crashed and burned if it was the master that was behind and caught up.
Use a helper that does the work for handle_commit AND handle_last.
