We require that ceph_con_close be called before we drop the connection,

We need to make sure we only swab the address during the banner once.  So
break process_banner out of process_connect, and clean up the surrounding
code so that these are distinct phases of the handshake.

We exchange struct ceph_entity_addr over the wire and store it on disk.
The sockaddr_storage.ss_family field, however, is host endianness.  So,
fix ss_family endianness to big endian when sending/receiving over the
wire.

A generic message passing library is used to communicate with all
other components in the Ceph file system.  The messenger library
provides ordered, reliable delivery of messages between two nodes in
the system.

This implementation is based on TCP.
