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.

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
coefficients were always used anyway.

When fix_sub_duration is used, and the duration fixing code is generating 0
duration, that is definitely zero, and not undefined or infinite (which may be
the case for decoded AVSubtitles depending on the codec), so it is safe to drop
it.
It fixes teletext subtitle sources, when the subtitles are transmitted twice
after each other for some reason.

Even if it does not matter at the moment, because subtitles with num_rect == 0
have no memory allocated, this is how we expect the users to use the API, a
returned AVSubtitle should be freed with avsubtitle_free.

It should not matter for real-life usage, it is just cleaner this way.

This more closely matches the actual use, also we use plain
strip without these flags for striping
