Comment (by danielk):

 (In [8426]) References #868. References #574.

 Fixes a bug with libmpeg2 decoding where we would report a frame as
 available for viewing before we got a STATE_SLICE with a display_fbuf.
 This would result in very blocky output after a seek to a keyframe. This
 fixes the blockyness for low-res PS streams, and reduces it for high-res
 TS stream. This also releases frames when libmpeg2 is done with them,
 which should mean less wackyness in low buffer situations (see [8425].)

 This bug was documented as a possible problem in the libmpeg2 decoder
 loop. But it doesn't cause problems during normal playback, only when
 seeking to I frames, or frames that come shortly after them.
