ext/a52dec/gsta52dec.*: Mark discont on outgoing buffers after receiving a DISCONT buffer or when we have a decoding ...

Browse source 
Original commit message from CVS:
* ext/a52dec/gsta52dec.c: (gst_a52dec_init), (gst_a52dec_push),
(gst_a52dec_sink_event), (gst_a52dec_handle_frame),
(gst_a52dec_chain), (gst_a52dec_change_state):
* ext/a52dec/gsta52dec.h:
Mark discont on outgoing buffers after receiving a DISCONT buffer or
when we have a decoding error.
We don't need to clear the cache when we receive a NEWSEGMENT event.
Clear buffer cache in DISCONT.
Add beginnings of GstSegment handling.
