* qatar/master: (22 commits) frwu: Employ more meaningful return values. fraps: Use av_fast_padded_malloc() instead of av_realloc() mjpegdec: use av_fast_padded_malloc() eatqi: use av_fast_padded_malloc() asv1: use av_fast_padded_malloc() avcodec: Add av_fast_padded_malloc(). swscale: enable dithering in MMX functions. swscale: make rgb24 function macros slightly smaller. avcodec.h: Remove some disabled cruft. swscale: remove obsolete comment. swscale-test: Drop unused argc and argv arguments from main(). zmbv: Employ more meaningful return values. zmbvenc: Employ more meaningful return values. vc1: prevent null pointer dereference on broken files zmbv: check av_realloc() return values and avoid memleaks on ENOMEM truespeech: align buffer ac3: Do not read past the end of ff_ac3_band_start_tab. dv: Fix small stack overread related to CVE-2011-3929 and CVE-2011-3936. dv: Fix null pointer dereference due to ach=0 dv: check stype ...
