QPID-3310 - Principal/Subject refactoring.

Refactoring to the connection/session objects to pass the Subject from Authentication tier to Access tier, rather than just
the Principal.  Change the access-control to be able to make access decisions based on Groups from the Authentication tier
whilst retaining support for groups declared within the ACL file itself.  Improve unit tests.

Applied patch by Keith Wall <keith.wall@gmail.com>
