98bdb8bf46 msgr: remove rank number from endpoint, since there's only one. 
Remove Endpoint's wait() method as it's unused.

d52e8d2a51 osd: fix MASKTRUNC 
This was looking at the wrong osd_op for the truncate_seq, which made it
essentially broken.  This was problematic any time the client SETTRUNC
reached an object (on a write after truncate) before the MDS TRIMTRUNC did.

ed96d871de mds: add NEW session state 
We want to register new sessions in the map so that they can be found when
we replay ESession events in the log.  Otherwise a client that connects
to the mds early will have one Session* on the connection, and another in
the map, and reconnect will fail.

Make sure we remove NEW sessions from the map on connection reset, so that
things gets freed.

Also, take mds_lock in ms_verify_authorizer.

93dd9f03ac mds: expose projected ctime is client is last versionlock wrlocker 
This fixes the problem where the client does a setattr on CTIME, but
doesn't actually see it.

Probably, though, the exposed ctime should be more precise: something like
the most recent projected value that the client is responsible, since we
may have multiple clients projecting pipelined values on the inode.

4bfa758bf5 hash: use native appropriately sized hash for word, not native host word size 
These shouldn't be used over the wire or on disk, but just in case.

Also, i suspect the 64-bit hash is probably faster than the 32bit one
twice?
