MediaPlayer.java has 3 new methods: * newRequest creates a Parcel that can be used to send data to the native player using invoke. * invoke issues synchronous calls to the native player using opaque parcels for the request and reply. IMediaPlayer.h has 1 new abstract method: * invoke The Midi and Vorbis players have a stub for these. So far only PV makes use of that new feature. To avoid any copy overhead, the JNI interface uses Parcel as a java object (no serialization/copy happens at the JNI layer). The remote interface token is inserted when the Parcel is constructed in java. That way the parcel is already routable when it reaches IMediaPlayer.cpp (proxy). No extra copy is needed there.
