Revise the API accordingly. For Media Control Server, make it a complete implementation (OTS still missing), and add an API the profile can use. This is mostly a complete rewrite.

This contains basic GGIT and state transition tests. Not all state transition tests are here, as they'd largely test the upper layer of the profile which is not tested now.

In practice, this seems to be enough to support media control keys on headsets. Some headsets (Creative Zen Hybrid Pro) also refuse to connect if there is no GMCS service.
