I began to re-insert the definitions of:

avs_is_yv12()
avs_get_pitch_p()
avs_get_read_ptr_p()
avs_get_write_ptr_p()
avs_load_library()
and macro AVS_FRAME_ALIGN

...which are used by libavformat/avisynth.c

...then saw they were all referenced in older files named after
AviSynth v2.5 which, understandably, needs leaving behind though its
header is still #included by avisynth.c. This is an input method to
FFmpeg I use to clear up certain frame-rate conversions, and so I'd
ask if anyone needs further help with altering this piece of FFmpeg.
