[FFmpeg-devel] [PATCH] Add av_picture_data_copy and reimplement av_picture_copy as a wrapper

[S.N. Hemanth Meenakshisundaram]

This patch goes on top of "Separate video specific BufferRef properties
into VideoProps" and is required for lavfi audio changes since
vsrc_buffer.c uses av_picture_copy but AVFilterBufferRef's data pointer
and linesize arrays need to be resized to 8 and shared with audio.

I can move av_picture_data_copy to libavcore/imgutils.c if necessary.
Also, I did not separate out the src picture into data and linesize
pointers since the name says 'avfilter_picture...'.

This is on top of mainline SVN and passes make lavfitest and make test.
