Reimplement the OMX backend for stagefright.

Besides a major cleanup and refactoring, OMX is now a singleton living in the media server, it listens for death notifications of node observers/clients that allocated OMX nodes and performs/attempts cleanup.

Changed APIs to conform to the rest of the system.
