media: OMX seek works for OMX_HEADBUFFERTYPE now.

1. Promote Stop() to engine interafce and make it Asynchronous.
2. Add Pause() and Flush() in engine interface.
3. Notify buffer return in ffmpeg engine so that future recycling could use it.
4. Add Pause logic in OMX decode engine.

to fully support seek in hardware path, some pipeline work and video render work is required. that will be in the next patch (maybe jia will write it).
1. some renderer hack is required for now. but current pause model of videoRenderBase is not suitable for hardware case. we need to resolve that.
2. Seek after EOS is not supported.
3. Seek for EGL image path is not yet tested, some code is required to return EGLImage buffer to allocator's side.
