75bd07f732 mpeg4videoenc: write 0 instead of vol_sprite_usage

e62a43f6b1 mpeg4videodec: move MpegEncContext.time_increment_bits to Mpeg4DecContext

3c8507a845 dcadec: add disable_xch private option. 
This supplements the deprecated request_channels-based control of XCh decoding.

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.

It was based on an old, seemingly incorrect specification, so default

c6080d8900 lavc: remove mp3_header_(de)compress bitstream filters 
They mangle the mp3 header in a non-standard way to save a few bytes.
