877f76ad33 swscale: Fix use of uninitialized values
(bug probably introduced from a marge of libav)

3c194f390f Replace "vector const" by "const vector" otherwise gcc 4.6.0 fails.
Given that this compiles fine with the Apple compiler that is probably
a gcc bug, but "const vector" is nicer anyway.

eb5a3ab7b0 swscale: fix compilation of bfin due to missing pixdesc.h header
This is required after sws_format_name() was replaced by
av_get_pix_fmt(), which is declared in libavutil/pixdesc.h.

    swscale: Remove unused variables in x86 code.

    libswscale/x86/swscale_template.c:2072: warning: unused variable ‘canMMX2BeUsed’
    libswscale/x86/swscale_template.c:2145: warning: unused variable ‘canMMX2BeUsed’

    swscale: delay allocation of formatConvBuffer().

    That means it won't be allocated when not needed. Alongside
    this, it fixes valgrind/fate-detected memory leaks.

78046dadc3 rgb2rgb: remove duplicate mmx/mmx2/3dnow/sse2 functions.
Many functions have such a prefix, but do not actually use any
instructions or features from that set, thus giving the false
impression that swscale is highly optimized for a particular
system, whereas in reality it is not.
