Make connection-factories public

This is a large change, but it is completely
a refactoring of code, not code changes.  The
connectionfactory classes are now public and
describe the connection backends (local and
tcp/ip).

Instead of putting the client code in a set
of files and the server code in a set of files,
we have local_backend and tcpip_backend which
include both client/server code.  The packet
type enums were moved to the global header file
to make them available to additional backends.
