The MinGW32 project is deprecating its old version macros.

The flag is not unconditionally added to CFLAGS either and the
programs built on the host do not get habitually fed to a debugger.

This fixes decoding, broken since 7e350379.

This is similar to what was done for the normal mp3 decoder in
f4a86bc9.

Also bump libavcodec micro and add an APIchanges entry saying that
av_frame_* should now be used instead of the lavc AVFrame functions.

This is a temporary workaround to allow deprecating
avcodec_get_frame_defaults(). The proper solution will be using a
properly allocated AVFrame in Picture.

avcodec_decode_audio4() resets the frame itself.

avcodec_decode_*() resets the frame itself.

This is a temporary workaround to allow deprecating
avcodec_get_frame_defaults(). The proper solution will be using a
properly allocated AVFrame in Picture.

ff_mpeg_unref_picture() already resets the frame.

avcodec_decode_audio4() will reset the frame itself.

avcodec_get_frame_defaults() will be deprecated.

Strictly speaking it is not correct to call it on refcounted frames, in
any case it is unnecessary, since filtered_frame is always unreferenced
after poll_filter() returns.

av_frame_free() should be used instead.

This enables a more POSIX-compliant printf implementation, that
allows using length modifiers like 'z'.

Use only proper AVFrame API (no assigning of whole frames, since that
hardcodes sizeof(AVFrame) into lavc).

Make a copy of the side data, so the caller can use av_frame_unref/free
on non-refcounted frames, eliminating the need for
avcodec_get_frame_defaults()/avcodec_free_frame().
