* qatar/master: (23 commits) doc: Check standalone compilation before submitting new components. Fix standalone compilation of pipe protocol. Fix standalone compilation of ac3_fixed encoder. Fix standalone compilation of binkaudio_dct / binkaudio_rdft decoders. Fix standalone compilation of IMC decoder. Fix standalone compilation of WTV demuxer. Fix standalone compilation of MXPEG decoder. flashsv: K&R cosmetics matroskaenc: fix memory leak vc1: make overlap filter for I-frames bit-exact. vc1dec: use s->start/end_mb_y instead of passing them as function args. Revert "VC1: merge idct8x8, coeff adjustments and put_pixels." Replace strncpy() with av_strlcpy(). indeo3: Eliminate use of long. get_bits: make cache unsigned to eliminate undefined signed overflow. asfdec: fix assert failure on invalid files avfilter: check malloc return values. Not pulled as reason for reindent is not pulled: mpegvideo: reindent. nutenc: check malloc return values. Not pulled due to much simpler solution in ffmpeg *: don't av_malloc(0). ... Conflicts: doc/developer.texi libavcodec/Makefile libavcodec/get_bits.h libavcodec/mpegvideo.c libavformat/Makefile libavutil/log.c Merged-by: Michael Niedermayer <michaelni@gmx.at>
