the new code is sometime faster sometimes slower but the difference is significant (~20%) so its optional and enabled with arnd=1

this is certainly not the most beautifull but it should work without -fomit-frame-pointer and PIC and gcc-4 vomits when ebp is given in a constraint directly even with -fomi-frame-pointer so theres not that much choice ...
if anyone knows a simpler/cleaner solution, dont hesitate to suggest it ...

patch replaces '()' for the correct '(void)' in function
declarations/prototypes which have no parameters. The '()' syntax tell
thats there is a variable list of arguments, so that the compiler cannot
check this. The extra CFLAG '-Wstrict-declarations' shows those cases.

Comments about a similar patch applied to ffmpeg:

That in C++ these mean the same, but in ANSI C the semantics are
different; function() is an (obsolete) K&R C style forward declaration,
it basically means that the function can have any number and any types
of parameters, effectively completely preventing the compiler from doing
any sort of type checking. -- Erik Slagter

Defining functions with unspecified arguments is allowed but bad.
With arguments unspecified the compiler can't report an error/warning
if the function is called with incorrect arguments. -- Måns Rullgård

The vec_mstrgb24 and vec_mstbgr24 macros should be opposites and not perform
the same things.
