987903826b Globally rename the header inclusion guard names. 
Consistently apply this rule: the guard name is obtained from the
filename by stripping the leading "lib", converting '/' and '.'  to
'_' and uppercasing the resulting name. Guard names in the root
directory have to be prefixed by "FFMPEG_".

2ccddc0211 Add explicit (int) cast to i386 optimized MUL* macros. 
Wrong result is returned when 16-bit value is passed as value.
Also fixes "Warning: using `%edx' instead of `%dx' due to `l' suffix".

dad6afb4cb stricter constraints of asm() blocks 
All these variables are used as left operands of a movd instruction,
which does accept only memory or register operands while the "g"
constraint also allows immediates. Use "rm" instead.
