Keep a per-OutputFile instance of it, thus making -fs work with multiple
output files.

By replacing
if (foo)
    <do stuff>

with
if (!foo)
    continue;
<do stuff>

Allows us to get rid of forward InputStream declaration.

Keep a per-OutputFile instance of it, thus making -ss work with multiple
output files.

Keep a per-OutputFile instance of it, thus making -t work with multiple
output files.

Instead store output streams in the same way as input streams.

Subsequent cherry picks are based on code prior to this, thus this needs to be rebased
on HEAD by a volunteer.
This reverts commit b25d931a.

Move the stream specifier to the option name.

New streams are always added to the last output file.

Move find_codec_or_die(), choose_codec(), new_output_stream() and
read_avserver_streams() below transcode() where they belong.

It's only used in opt_output_file(), so move it right above
opt_output_file().

parse_forced_key_frames() is only used in new_video_stream(), so move it
right above new_video_stream().

The new option doesn't depend on its placement wrt -new* options (which
don't exist anymore) and works in a similar way as per-stream AVOptions.

-[vas]codec remain as aliases to -codec:[vas]

Nothing except x264 uses them and native x264 presets should be used
with private options.

This is needed because the following cherry picks are based on code prior of this

This reverts commit f712f6c8.

New syntax contains an optional stream type, allowing to refer to n-th
stream of specific type.

Omitting stream number now maps all streams of the given type.

They are confusing, irregular and redundant -- -map already contains all
the information.  Stream maps can now be parsed in opt_output_file().

Add a more user-friendly default behavior in case no maps are present.

Breaks -programid for now, but it never worked properly anyway. A better
solution will be written soon.

Before, it took an input and output file index, now it only takes an
input file and applies to the next output file.

Stream/chapter/program specification is now part of the option name and
the delimiter was changed from ',' to ':' to be consistent with the
similar feature for AVOptions.
