4aed0476fa mds: keep locks in sync state when MDS is readonly 
when transit locks to sync state, we may submit new entries to the log.
This should be safe as long as we don't trim old log segments.

2d4a746fa9 mds: don't trim log when MDS is readonly 
When MDS is readonly, keep metadata objects (not include the journal) of
cephfs unchanged. This allows us to submit new entries to the log while
MDS is readonly. (Log entries submitted after MDS becomes readonly can
be safely dropped)

01df222712 osd: tolerate sessionless con in fast dispatch path 
We can now get a session cleared from a Connection at any time.  Change
the assert to an if in ms_fast_dispatch to cope.  It's pretty rare, but it
can happen, especially with delay injection.  In particular, a racing
thread can call mark_down() on us.

ee3b5b2661 osd/osd_types: remove cat_sum from object_stat_collection_t 
This type is now just a useless wrapper around object_stat_sum_t, but that
is not easy to drop.

Note that now if we load and reencode a legacy object we'll drop those
fields.  We would mark the incompat flag in the object corpus accordingly,
but nothing in there populates the cat fields.

efeaaaa0b0 mds: in segment expiry, use end instead of start 
Previously we were always leaving the last log
segment un-expired from Journaler's POV, because
we were updating expire_pos to the *start* of the
expired journal segment instead of the *end*.

This was harmless, but cleaning it up makes it
easier to see what's going on during journal flushes
in testing.
