ANativeWindow: update queue/dequeue/cancel w/ sync

This change deprecates the existing queueBuffer, dequeueBuffer, lockBuffer, and
cancelBuffer functions, and replaces them with a queueBuffer, dequeueBuffer,
and cancelBuffer function that accepts or returns a libsync fence file
descriptor.  It also adds the native_window_dequeue_buffer_and_wait convenience
function.
