client: Add an entry point for dispatching a queue without blocking

Browse source 
On the client side EGL, all the wl_buffer.release events need to be
processed before buffer allocation, otherwise a third buffer might
be allocated unnecessarily. However, the buffer allocation should
not block in the case no event was received. In order to do that, a
non-blocking queue dispatch function is needed.
