This reverts commit fd91a3ec.

The bug it introduced has been fixed.

Move the lavc/imgconvert functions and rename them as follows:
avpicture_get_size -> av_image_get_buffer_size()
avpicture_fill     -> av_image_fill_arrays()
avpicture_layout   -> av_image_copy_to_buffer()

The new functions have an align parameter, which allows to define the
linesize alignment assumed in the buffer (which is set or read).

The names of the functions are consistent with the lavu/samples API
(av_samples_get_buffer_size(), av_samples_fill_arrays()).

This reverts commit 82992604.

It breaks shared builds on x86_64.

This reverts commit 8725da49.

Necerrary to revert 82992604.

Will help factorization with the pending -af patch, and add some checks
missing in the original code.

It was deprecated and removed after the recent 2->3 major bump.

Simplify code.

Also show them in a more parsable/consistent fashion.

Group lavfi headers together, slightly improve readability.

This is required for isatty, which exists on MSVC and is found by
configure, but is provided by io.h instead of unistd.h.

This adds whitespace around operators, aligns line continuation
backslashes, and breaks long lines.  Also fixes an ifdef halfway
through a statement.  The one line of duplication this saved is
not worth the ugliness.

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.
