66499f34b5 mpegvideo: do not set current_picture_ptr in decoders 
This code was originally added in
5f1948111a to h263 to set decoded frame
pts to some random numbers (removed in
a1c5cc429d) and then cargo culted to other
decoders.

The code is left in h263dec for now, since some part of the decoder
(apparently OBMC) relies on the specific previous frame to be reused.

ac1fc92ea4 vc1dec: move setting repeat_pict after frame_start() has been called. 
This will allow removing the hacks where each decoder sets
current_picture_ptr on its own.

amd3dnow optimizations are being deprecated. Thus the former should

01f6df01b6 go2meeting: disallow tile dimensions that are not multiple of 16 
Original decoder seems to always use 176x128 tiles anyway and this helps
avoiding lots of issues with odd tile sizes in fuzzed files.

220494ad0b dcadec: treat all 2-channel modes as Stereo in dca_downmix. 
The check for (prim_channels > 2) before calling dca_downmix made these
cases unreachable, but now 2.1 layouts will go through the downmix code.
Having dual mono, Lt/Rt and sum-difference layouts print errors when
regular Stereo doesn't seems pointless.

149438cfe5 dca: improve default stereo downmix coefficients. 
Previous coefficients were producing a non-normalized, incorrect Lt/Rt downmix.

The new coefficients produce a standard Lo/Ro downmix with 3dB attenuation.

This should match the typical default coefficients used by DTS encoders.
