710b8df949 dsputil: remove ff_emulated_edge_mc macro used in one place 
This macro can cause problems in conjunction with the bitdepth
template expansion.  It was presumably added to keep source
compatibility when high bitdepth support was added.  However,
emulated_edge_mc is a dsputil pointer and should not be called
directly, so there is little reason to keep such a macro.

49c7006c7e dca: set AVCodecContext frame_size for DTS audio 
Set the frame size when decoding DTS audio.

This has the side effect of fixing the computation of timestamps for DTS-HD in compute_pkt_fields.  Since frame_size is
not currently set, the duration of a frame is being guessed based on the streams bitrate.  But for DTS-HD, the bitrate
currently used is the rate of the DTS core which is much different than the whole DTS-HD stream and leads to a wildly
inaccurate frame duration estimate.
