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.

lavc: Drop deprecated request_channels related functions
Merged-by: Hendrik Leppkes <h.leppkes@gmail.com>
When request_channel_layout is 0,
all substreams should be decoded.
Thanks to Michael Niedermayer for spotting.
Also fix a mismatch between the parser and
decoder when request_channel_layout is a
subset of Stereo.
Don't decode further substreams if request_channel_layout
is a subset of the current substream's channel_layout.
Before, we would only discard further substreams if
request_channel_layout matched the substream's
channel_layout extactly, thus decoding additional
channels which the caller would probably end up downmixing.

Also stop storing the channel arrangement in the header info, as it's unused outside of ff_mlp_read_major_sync.
