simd_align_16 is a configure item that can be enabled or disabled,
it's not a variable containing a list of other configure items

This makes sure the default behaviour of using the internal encoder
stays the same regardless if libtwolame is enabled or not (as for
any external library).

This fixes fate-lavf-mpg if libav is built with libtwolame enabled.

'ret' can only be used without initialization if s->height <= 0, which can
only happen if avctx->height <= 0, which is validated elsewhere. Doesn't hurt
to still initialize it though.

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.
