Android emulator opengl - unit testing render control api

This adds minimal rendering control api codec that is used by opengl codec
unit tests. The api is used to pass messages regarding resource creation
(surfaces, opengl context) and swapbuffers notifications.
The actual encoder and decoder code is generated using 'emugen'
