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

This condition should be impossible and was checked for by asserts.
the asserts are moved up in this merge to gurantee that no out of array
access can happen even if the state is "impossible".
Also if such impossible states could somehow be created, that should
be dealt with and not silently ignored.

This code changes the input packet, which is read only and can in
rare circumstances lead to decoder errors. (i run into one of these in
the audio decoder, which corrupted the packet during av_find_stream_info()
so that actual decoding that single packet failed later)
Until a better fix is implemented, this commit limits the problem.
A better fix might be to make the subtitle decoders not depend on
data[size] = 0 or to copy their input when this is not the case.
These functions are intended for use with side_data which comes in an
AVPacket.
