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.

d36beb3f69 Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf. 
None of these symbols should be accessed directly, so declare them as
hidden.

ba87f0801d Remove explicit filename from Doxygen @file commands. 
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.

8790961d7e mlp_parser: Fix memleak. 
ff_combine_frame() is called, which allocates ParseContext->buffer if needed,
so ff_parse_close() must be called to free it.

7e2ef1b9e1 Fix possible crashes in mlp parser, it tries to go back 7 bytes after 
finding the 4-byte signature.
Add a check that ignores the signature if we do not have enough previous
data to go back at least 7 bytes.
