9b0d44ef67 Do not attempt to use the unscaled yuv2rgb converter when height is odd because 
it will overflow the buffer by 1 line. This might have been exploitable.

7ad6469eae Convert asm keyword into __asm__. 
Neither the asm() nor the __asm__() keyword is not part of the C99
standard, but while GCC accepts the former in C89 syntax, it is not
accepted in C99 unless GNU extensions are turned on (with -fasm). The
latter form is accepted in any syntax as an extension (without
requiring further command-line options).

Sun Studio C99 compiler also does not accept asm() while accepting
__asm__(), albeit reporting warnings that it's not valid C99 synta.

b5c44b1ab6 Mark some symbols in swscale.c as constant. 
These are only used in swscale_template.c (and thus don't need to be
made extern), and can be declared as ASM constants.

d0b69b2855 Mark dither_2x2_{8,4} static to swscale.c 
These two tables are not used outside swscale.c even though they are
declared also in yuv2rgb.c.

b82ecd6258 The yuv->rgb tables are too small for cliping to be avoidable, 
thus revert the respective optimization. The table generator code
has to be rewritten anyway one day by some volunteer because its
not LGPL, fixing the GPL table generator thus seems like wasted time.
