BufferQueue improvements and APIs changes
this is the first step of a series of improvements to
BufferQueue. A few things happen in this change:
- setSynchronousMode() goes away as well as the SynchronousModeAllowed flag
- BufferQueue now defaults to (what used to be) synchronous mode
- a new "controlled by app" flag is passed when creating consumers and producers
those flags are used to put the BufferQueue in a mode where it
will never block if both flags are set. This is achieved by:
- returning an error from dequeueBuffer() if it would block
- making sure a buffer is always available by replacing
the previous buffer with the new one in queueBuffer()
(note: this is similar to what asynchrnous mode used to be)
Note: in this change EGL's swap-interval 0 is broken; this will be
fixed in another change.
