Include a type/version in ceph_entity_addr and filepath. Include extra
byte in filepath encoding as necessary.

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 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.

This avoids the fugly pass by reference and makes the code a bit easier
to read.

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.
