ceph: drop src address(es) from message header [new protocol feature]
The CEPH_FEATURE_NOSRCADDR protocol feature avoids putting the full source
address in each message header (twice). This patch switches the client to
the new scheme, and _requires_ this feature on the server. The server
will support both the old and new schemes. That means an old client will
work with a new server, but a new client will not work with an old server.
