c1e7de8f62 mlp_parser: fix request_channel_layout behavior.
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.

c0c45188e5 mlp: improve request_channel_layout behavior.
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.

ed1b01131e mlp: implement support for AVCodecContext.request_channel_layout.
Also wrap usage of AVCodecContext.request_channels in FF_API_REQUEST_CHANNELS directives.

b0c7e3ffd0 mlp_parser: account for AVCodecContext.request_channels when setting the channel layout.
Allows users to configure the output based on what's actually decoded, rather than the full native layout.

99ccd2ba10 mlp: store the channel layout for each substream.
Also stop storing the channel arrangement in the header info, as it's unused outside of ff_mlp_read_major_sync.

cc276c85d1 Make channel layout masks unsigned
It makes more sense for a bit mask to use an unsigned type.
The change should be source and binary compatible on all
supported systems, hence micro version bump.

Fixes a few invalid shifts.

Passing an explicit filename to this command is only necessary if the
documentation in the @file block refers to a file different from the
one the block resides in.
