This is now possible since the code allocating OutputFile can see
sizeof(Muxer). Avoids the overhead and extra complexity of allocating
two objects instead of one.
Similar to what is done e.g. for AVStream/FFStream in lavf.
ffmpeg_opt.c currently contains code for
- parsing the options provided on the command line
- opening and initializing input files based on these options
- opening and initializing output files based on these options
The code dealing with each of these is for the most part disjoint, so it
makes sense to move them to separate files. Beyond reducing the quite
considerable size of ffmpeg_opt.c, this will also allow exposing muxer
internals (currently private to ffmpeg_mux.c) to the initialization
code, thus removing the awkward separation currently in place.
qsvenc makes a copy when the input in system memory is not padded as the
SDK requires, however the padding area is not filled with right data

Doxygen does not properly form references that span multiple levels,
so instead reword it a bit and manually add the references to what
they should point to.
The FF_PAD_STRUCTURE is too complex for doxygen to be able to
properly handle, resulting in completely broken AVBPrint documentation.
To fix that, tell Doxygen what to expand that macro to.
Avoids doxy to interpret these as internal references forced by the #
character, fixing the warnings:
warning: explicit link request to 'nanoTime()' could not be resolved
warning: explicit link request to 'releaseOutputBuffer(int,long)'
could not be resolved
The intention here was probably to document this as use of
conditionals does not make sense in a comment.
Fixes doxy warning:
warning: explicit link request to 'if' could not be resolved
Separate the blocks to make the grouping easier to grasp,
add the file properly to the group and fix the file description
incorrectly used as filename, fixing the following doxy warning:
warning: the name 'Colorspace' supplied as the argument in
the \file statement is not an input file
Make it a bit easier to grasp the grouping when not
unnecessarily splitting comment blocks.
Additionally do not try to add lavu_video_stereo3d to itself, resolving
the following doxy warning:
warning: Refusing to add group lavu_video_stereo3d to itself
