[FFmpeg-cvslog] Merge commit 'ec36aa69448f20a78d8c4588265022e0b2272ab5'

[Geek.Song]

Sorry. I must clarify that "#define HAVE_AVX 1" is defined in my
config.h in previous version, but because some implementation code
have been EXCLUDED by "#define HAVE_AVX_EXTERNAL 0" in this merge, so
the Linker fail to pass, such as:
......
LD      libavutil/avutil.dll
Creating library file: libavutil/libavutil.dll.a
libavutil/x86/float_dsp_init.o:float_dsp_init.c:(.text+0x25):
undefined reference to `ff_vector_fmul_avx'
libavutil/x86/float_dsp_init.o:float_dsp_init.c:(.text+0x2c):
undefined reference to `ff_vector_fmac_scalar_avx'
collect2: ld returned 1 exit status
make: *** [libavutil/avutil.dll] Error 1
