vstart.sh:  Use ./init-ceph instead of CEPH_BIN

This effectively reverts faddb80c4230acad2b4a17aa6cbf0c30ae8d24a9
which prevented vstart.sh from being used in an enviroment where
CEPH_BIN pointed to a make install target.

osd: fix populate_obc_watchers() assert

There is one case where populate_obc_watchers gets called when the object
is missing: during a revert.  And in that case we *should* do the populate,
since all that is getting reverted is the object version.

mds: fix handling of cache_expire export

During export, between the warning stage and the final notify, we may
get cache expire messages because the replicas are sending to both us
and the new auth.  This check should look for >= WARNING so that it
includes the EXPORTING states as well as the portion of WARNING after
we heard from that replica.  This aligns the conditional with the
following assert such that they are properly mutually exclusive.

client: do not reset session state on reopened sessions

We can have a sequence one the MDS like:

 - queue REQUEST_CLOSE to journal
 - force_open, queue open to journal
 - request_close acked, do nothing
 - force_open acked, send OPEN

In this case, the MDS never actually closed the session, and all of the
state remained valid.  The client, however, gets a suprious OPEN
message and resets the session state.

Fix this by not resetting that state.

A nicer fix might be to not send the second OPEN at all, but that would
require a REOPENING state on the MDS which is more complicated; this is
good enough.  Also, that approach might not give the client an
appropriate opportunity to say "um, no..." and resend the
REQUEST_CLOSE.
