If we explicitly close a connection, or there is a socket error, we need
to drop any partially received message.

Also, print fsid using standard format, NOT hex dump.

For lossy connections we drop all state on socket errors, so there is no
reason to keep sent ceph_msg's around.

The server indicates whether a connection is lossy; set our LOSSYTX bit
appropriately. Do not set lossy bit on outgoing connections.

Carry a ceph_msg reference for connection->out_msg. This will allow us to
make out_sent optional.

We never allocate the ceph_buffer and buffer separtely, so use a single
constructor.
Disallow put on NULL buffer; make the caller check.

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.

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.

We require that ceph_con_close be called before we drop the connection,
so this is unneeded. Just BUG if con->sock != NULL.

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.

The port is informational only, but we should make it correct.

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.

The mon request headers now include session_mon information that must

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.
