lavfi: rename AVFilterBufferRefVideoProps.pixel_aspect to sample_aspect_ratio
Improve consistency with libavcodec.
This breaks libavfilter API/ABI.
The non-sequential 2.1.0 -> 2.4.0 bump is due to the mess previouslydone with the lavfi minor number.
Merge libavcore into libavutil
Done to keep ABI compatible. Otherwise this is just silly
Add sample_aspect_ratio to AVFilterLink
In libavfilter, use consistently "Copyright (c)" in the licenseheaders.
