* commit '6860b4081d046558c44b1b42f22022ea341a2a73': x86: include x86inc.asm in x86util.asm cng: Reindent some incorrectly indented lines cngdec: Allow flushing the decoder cngdec: Make the dbov variable have the right unit cngdec: Fix the memset size to cover the full array cngdec: Update the LPC coefficients after averaging the reflection coefficients configure: fix print_config() with broke awks Conflicts: libavcodec/x86/ac3dsp.asm libavcodec/x86/dct32.asm libavcodec/x86/deinterlace.asm libavcodec/x86/dsputil.asm libavcodec/x86/dsputilenc.asm libavcodec/x86/fft.asm libavcodec/x86/fmtconvert.asm libavcodec/x86/h264_chromamc.asm libavcodec/x86/h264_deblock.asm libavcodec/x86/h264_deblock_10bit.asm libavcodec/x86/h264_idct.asm libavcodec/x86/h264_idct_10bit.asm libavcodec/x86/h264_intrapred.asm libavcodec/x86/h264_intrapred_10bit.asm libavcodec/x86/h264_weight.asm libavcodec/x86/vc1dsp.asm libavcodec/x86/vp3dsp.asm libavcodec/x86/vp56dsp.asm libavcodec/x86/vp8dsp.asm Merged-by: Michael Niedermayer <michaelni@gmx.at>
