* qatar/master: (21 commits) build: simplify commands for clean target swscale: split swscale.c in unscaled and generic conversion routines. swscale: cosmetics. swscale: integrate (literally) swscale_template.c in swscale.c. swscale: split out x86/swscale_template.c from swscale.c. swscale: enable hScale_altivec_real. swscale: split out ppc _template.c files from main swscale.c. swscale: remove indirections in ppc/swscale_template.c. swscale: split out unscaled altivec YUV converters in their own file. mpegvideoenc: fix multislice fate tests with threading disabled. mpegts: Wrap #ifdef DEBUG and av_hex_dump_log() combination in a macro. build: Simplify texi2html invocation through the --output option. Mark some variables with av_unused Replace avcodec_get_pix_fmt_name() by av_get_pix_fmt_name(). svq3: Check negative mb_type to fix potential crash. svq3: Move svq3-specific fields to their own context. rawdec: initialize return value to 0. Remove unused get_psnr() prototype rawdec: don't leak option strings. bktr: get default framerate from video standard. ... Merged-by: Michael Niedermayer <michaelni@gmx.at>pull/2/head
