dv: fix weight table for 2x4x8 transform

The coefficients must be in the appropriate zigzag scan order.
Also fix their values at the same time, as they were pretty wrong.

matroskaenc: write correct Display{Width, Height} in stereo encoding

should be the raw amount of pixels (for example 3840x1080 for full HD side by
side) and the DisplayWidth/Height in pixels should be the amount of pixels for
one plane (1920x1080 for that full HD stream)."

So, move the aspect ratio check in the mkv_write_stereo_mode() function
and always write the embl when stereo format and/or aspect ration is set.
Also add a few comments to that function.
