Simplify code.

Also show them in a more parsable/consistent fashion.

Group lavfi headers together, slightly improve readability.

On MSVC, gmtime returns NULL for values outside of their supported
range (and these show up in our fate test). This doesn't seem
to affect the actual fate test result.

Deprecate functions:
avfilter_fill_frame_from_buffer_ref
avfilter_fill_frame_from_audio_buffer_ref
avfilter_fill_frame_from_video_buffer_ref

and schedule to drop them at the next API major bump.

The function avfilter_copy_buf_props() should be used instead.

libavfilter API was designed in order to be clarly distinguished from the
libavcodec API, including avcodec.h in avfilter.h is not going to help to
stick to this principle.

The inclusion of libavutil/audioconvert.h in many files was required
because avcodec.h includes audioconvert.h.

libavfilter/avcodec.h is where the lavc/lavfi interface should be
entirely placed.

version.h seems the right place for FF_API_ definitions.

this matches sox and should fix ticket1119

Hardly anyone would want 8bit today, 16bit is a much more reasonable
default.

Currently if a pattern is given we search for up to the fifth file name in
that sequence. This option sets that limit to an arbitrary number.

MSVC has isatty (in io.h), but not unistd.h. (isatty isn't called
at all for windows, since there's a special case block for that.)

Tags may contain attached picture, which will be exported as video
streams.

This ensures that the audio stream is always the first.

Right now, it's uint16_t, but for itunes metadata a 32bit number is
stored in it.

This adds the capability to start counting file number from an arbitrary

This includes a few lines of trivial code from FFmpeg codebase.

Also ensure that all such filters get a non-NULL name. Should fix FATE
failures on some architectures after
58b049f2.

Because of a mistake during merging the code for simple and complex
filtergraphs, -async inserts an asyncts filter both on input and output.
Remove the output hunk.
