Fix incoming callback and binding issues.

- Created queues to handle cases where callbacks were getting dropped while
the service was connecting.
- Fixed DeadObjectExceptions when the in-call ui was being re-installed.
- Change to a single connection object to fix connection leak where every
re-bind caused connection to double.
- Split caller information from Call into CallIdentification object.
