* qatar/master: yuv4mpeg: return proper error codes. Give all anonymously typedeffed structs in headers a name fate: Add parseutils test parseutils-test: Drop random colors from parsing test vf_pad/scale: use double precision for aspect ratios. build: error on variable-length arrays ppc: swscale: rework yuv2planeX_altivec() ppc: fmtconvert: kill VLA in float_to_int16_interleave_altivec() x86: dsputil: kill VLA in gmc_mmx() libspeexenc: Updated commentary to reflect recent changes libspeexenc: Add an option for enabling DTX doc/APIchanges: fill in missing dates and hashes. lavr: bump major to 1 and declare it stable. lavr: change the type of the data buffers to uint8_t**. lavc: deprecate the audio resampling API. Conflicts: cmdutils.h configure doc/APIchanges ffplay.c libavcodec/dwt.h libavcodec/libspeexenc.c libavfilter/vf_pad.c libavfilter/vf_scale.c libavformat/asf.h tests/fate/libavutil.mak tests/ref/fate/parseutils Merged-by: Michael Niedermayer <michaelni@gmx.at>
