507c2a5774 libswscale: arm: Don't assume aligned output in yuv2rgb functions 
This fixes failures in recently added checkasm tests.

While the buffers in most cases are aligned, libswscale in general
can't assume the output to be aligned.

f4bfdf7893 lavfi: move ff_parse_pixel_format() to vf_format, its only caller 
The only thing this function does beyond calling av_get_pix_fmt() is
falling back onto parsing the argument as a number. No other filters
should need to do this.

1afe42852b lavfi/internal: move functions used by filters to filters.h 
internal.h currently mixes interfaces intended to be used by filters
with those that should be limited to generic filter- or graph-level
code.
