The previous version checked the filter context name,
instead of checking the filter name.
The new version just uses the same type as the input.

The list goes back to being simple integers,
and avfilter_make_format64_list is fixed to work
with the correct structure directly.

The file now contains both an audio and a video split filter.

The move allows to share the init code already used by split.

This simplifies the code but also fix a warning: ff_id3v1_genre_str
array contains const strings so do the string dup now instead of in
av_dict_set().

This also avoids a memleak.

Note: the condition looked wrong in the first place ("if DTS is not
defined, then set PTS to that undefined value [...]").

Avoid some memleaks.

All the other examples already use the system installed headers.

These rules are already in gmake builtins.

Reduce diff against avconv, and change some doxycomments into normal
comments (no point in doxifying ffmpeg internal fields).

Most of the code is moved to buffersrc.c
to help Git see the similarities.

src_buffer.c still contains the obsolete compatibility functions.

The format change detection code was removed as it has been
implemented directly in ffmpeg.
It can easily be brought back from the history.

It restores ABI compatibility with libav.

The fields that move were very recent or morally private.

These helpers are handy, just notice the user it is done using lavfi.
