Sage Weil c86a2930cc ceph: carry explicit msg reference for currently sending message
Carry a ceph_msg reference for connection->out_msg.  This will allow us to
make out_sent optional.

Sage Weil b6c1d5b81e ceph: simplify ceph_buffer interface
We never allocate the ceph_buffer and buffer separtely, so use a single
constructor.

Disallow put on NULL buffer; make the caller check.

Sage Weil 03c677e1d1 ceph: reset msgr backoff during open, not after successful handshake
Reset the backoff delay when we reopen the connection, so that the delays
for any initial connection problems are reasonable.  We were resetting only
after a successful handshake, which was of limited utility.

Sage Weil 4e7a5dcd1b ceph: negotiate authentication protocol; implement AUTH_NONE protocol
When we open a monitor session, we send an initial AUTH message listing
the auth protocols we support, our entity name, and (possibly) a previously
assigned global_id.  The monitor chooses a protocol and responds with an
initial message.

Initially implement AUTH_NONE, a dummy protocol that provides no security,
but works within the new framework.  It generates 'authorizers' that are
used when connecting to (mds, osd) services that simply state our entity
name and global_id.

This is a wire protocol change.

Sage Weil 71ececdaca ceph: remove unnecessary ceph_con_shutdown
We require that ceph_con_close be called before we drop the connection,
so this is unneeded.  Just BUG if con->sock != NULL.

Sage Weil eed0ef2caf ceph: separate banner and connect during handshake into distinct stages
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.

Sage Weil f28bcfbe66 ceph: convert port endianness
The port is informational only, but we should make it correct.

Sage Weil 63f2d21195 ceph: use fixed endian encoding for ceph_entity_addr
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.

Sage Weil 31b8006e1d ceph: messenger library
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.
