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.

the purgatory list wasn't needed anymore; in fact it had no effect as
buffer life-time management is now handled by the BufferQueue.
For QueuesToWindowComposer we keep a list of wp<> on the IBinder
for IGraphicBufferProducers we hand over to clients so we can
easily check if an IGraphicBufferProducer is ours. We clean-up the
list when our IGraphicBufferProducer are destroyed.

The C++ class names don't match what the classes do, so rename
ISurfaceTexture to IGraphicBufferProducer, and SurfaceTexture to
GLConsumer.

indeed, connect and queueBuffer return the same data, so it's
easier to have them use the same protocol.

the first time a surface was connected, the values returned
by query NATIVE_WINDOW_DEFAULT_{WIDTH|HEIGHT} and
NATIVE_WINDOW_TRANSFORM_HINT were wrong until a call
to queueBuffer was performed.

This change makes SurfaceFlinger's SurfaceTexture objects default to
async mode whenever a camera or video decoder connects. This behavior
can be disabled by #defining NEVER_DEFAULT_TO_ASYNC_MODE.
