Make isReady of FakeRenderer more realistic.

Browse source 
Currently the renderer is only ready when the input stream has more data to
read. Actual renderers, however, are also ready as long as their output buffer
contains some audio/video samples to play, roughly corresponding to the fact
that the playback time hasn't reached the timestamp of the last buffered
sample. Added a isready flag to FakeRenderer to simulate this behaviour.
