stagefright: Rework GraphicBufferSource - step 1
- Abstract buffer reference counting so that it does not intimately
assume a BufferQueue. Move releasing acquired buffers into a
callback as this is BQ specific. Having vectors for slots is also
BQ specific.
Use shared, copiable objects to manage buffers and their lifecycles:
CachedBuffer: a cached buffer in a slot
AcquiredBuffer: a buffer acquired from the producer that will
need to be released (and will get released when all copies of
this object go out of scope)
VideoBuffer: an acquired buffer with metadata
- Rename variables to be more descriptive.
- Move associated methods and variables closer together.
- Document methods and some of the operations of GraphicBufferSource.
