GstDroidBufferPool is kind of a hack to throttle the decoder output a bit.

Since we never reallocate the buffers then it is safe to ignore resetting
num_buffers. We also reset it in _start().

The pool recycles the buffers so we decrease num_buffers when we hand a buffer to
the decoder and increment it again when we get a buffer back in _reset_buffer()
