[FFmpeg-devel] [PATCH 4/9] avfilter/bwdifdsp: Avoid including ff_bwdif_filter_line3_c()

[Andreas Rheinhardt <andreas.rheinhardt@outlook.com>]

This function is used by the AARCH64 code to filter a few
remaining lines in case the dimensions are not suitably
aligned; it is furthermore also used by checkasm to actually
test the AARCH64 code against. But it is normally not used
and this patch therefore moves it in bwdifdsp.h as a static
inline function so that it can be avoided if possible
or inlined where necessary.
