PG::activate: handle peer contigious with primary, but not auth_log
The added case covers a situation where a replica is not contiguous with
the auth_log, but is contiguous with the primary. Reshuffling the
active set to handle this would be tricky, so instead we just go ahead
and backfill it anyway. This is probably preferrable in any case since
the replica in question would have to be significantly behind.

PG: do not serve requests until replicas have activated
There are two problems:
1) We choose the min last_update amoung peers with the max local-les
value as an upper bound on requests which could have been reported to
the client as committed. We then, for ec pools, roll back to that point
to ensure that we don't inadvertently commit to an update which fewer
than K replicas actually saw. If the primary sets local-les, accepts an
update from a client, and there is a new interval before any of the
replicas have been activated, we will end up being forced to use that
update which no other replica has seen as the new last_update. This
will cause the object to become unfound. We don't have this problem as
long as all active replicas agree on last_update before we accept IO.
2) Even for replicated pools, we would then immediately respond to the
request which created the primary-only update with a commit since it is
in the log and we have no outstanding repops. If we then lose that
primary before any of the replicas in the new interval record the new
log, we will not only lose the object, but also the log entry recording
it, which will result in a lost write.
For these reasons, it seems like we need to wait for the replicas to
activate before we can process new requests essentially because whatever
update we select as last_update is essentially regarded as committed as
soon as we accept IO.

mds: fix owner check of file lock
flock and posix lock do not use process ID as owner identifier.
The process ID of who holds the lock is just for F_GETLK fcntl(2).
For linux kernel, File lock's owner identifier is the file pointer
through which the lock is requested.
The fix is do not take the 'pid_namespace' into consideration when
checking conflict locks. Also rename the 'pid' fields of struct
ceph_mds_request_args and struct ceph_filelock to 'owner', rename
'pid_namespace' fields to 'pid'.
The kclient counterpart of this patch modifies the flock code to
assign the file pointer to the 'owner' field of lock message. It
also set the most significant bit of the 'owner' field. We can use
that bit to distinguish between old and new clients.
