* 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.
