Second attempt. Since previously: - much simpler usage (you basically just call av_pixelutils_get_sad_fn() as a user); filters patches updated accordingly. - 16x16 mmxext added (thanks jamrial) - FATE tests
Note for the context since I didn't write anything about it in the previous patchset: this is in continuation to avcodec/AVDCT in order to drop dsputils which has been removed from Libav (but kept in FFmpeg for compatibility). After this patchset, libavfilter should be free of dsputils leftovers. BTW, the scope of the pixelutils is to have a bunch of optimized pixel utilities for filters. Currently, we only have SAD utils, more functions are welcome as long as it sticks to this very generic pixels scope: for example, DCT stuff belongs to avcodec/AVDCT (at least for now), and an optimized pixel function that won't be useful for multiple filters belongs in the local context of that filter. A good candidate could be SAD for full-frames, or maybe pixel lines functions for interlaced stuff. pixelutils are optional. It will be enabled in libavutil only on demand (typically if a filter uses it). The default full build will contain it, but if you --disable-filters, libavutil will no longer integrate it. Ah, and before I forget; we are kind of in a hurry since this is meant to avoid some ABI issues in the next release. So if you want to review it, please do it quickly.
