This is done by actually handling the "prev_values" in the cascaded LMS data
as if it were int16_t, thus requiring switching at various locations the
computations.

Regression since 29412821.

16bits samples with CDLMS orders of 8 are currently unsupported, but have never
been encountered before.

However, 8 seems to be the most frequent, if not the only order used for 24bits.
In that case, the dsp functions are fine with handling order that are multiples
of 8, so silence the warning.

The deprecated avcodec_decode_video2() and avcodec_decode_audio4()
functions called av_packet_split_side_data() on the input packets. This
is required for packets produced by libavformat with the
AVFMT_FLAG_KEEP_SIDE_DATA flag unset (which is unfortunately the
default).

The new API didn't do this yet, although it didn't matter as no decoder
supports the new API yet. The emulation layer for the old API calls the
old API functions, which took care of the splitting. Add this code to
the new API codec entrypoints too, because we shouldn't send essentially
corrupted data to decoders.
