c2f7417eeb vc1: move MpegEncContext.resync_marker into VC1Context. 
The field still remains in MpegEncContext because it is used by the
mpeg4 decoder.

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.
