831018b0bb mpeg4audio: Make avpriv_copy_pce_data() inline
The function currently accepts a PutBitContext and a GetBitContext,
which hardcodes their sizes into the lavc ABI. Since the function is
quite small and only called in a few places, the simplest solution is
making it inline, thus avoiding a runtime dependency completely.

970c76f322 mlp_parser: Drop in-parser downmix functionality
request_channel_layout is a decoder option and it makes no sense
to have it in a parser.

This feature was needed in the past when the decoder was allowed
to reuse the avctx from the demuxer. Nowadays the decoder receives
only the parameters from it, already containing the real channel
layout (and the correct request_channel_layout option).

After initialization the decoder overwrites the channel layout
with the downmixed one that is actually output, so there is no need
to preserve this functionality in the parser.

6af014f402 vaapi_encode: Use gop_size consistently in RC parameters
The non-H.26[45] codecs already use this form.  Since we don't
currently generate I frames for codecs which support them separately
to IDR, the p_per_i variable is set to infinity by default so that it
doesn't interfere with any other calculation.  (All the code for I
frames still exists, and it works for H.264 if set manually.)

e788ca05a7 hevcdec: Use LOCAL_ALIGNED_* for declaring local variables with alignment
Not all compilers can do alignment larger than the normal stack alignment
for variables on the stack. In these cases, the LOCAL_ALIGNED_* macros
produce the workaround alignment wrapper consisting of a padded array
and a pointer variable.

This fixes the hevc fate tests on RVCT/ARMCC after adding IDCT assembly
that actually assumes/relies on this alignment.
