Mangling with #defines is not nice, as we may end removing
the macro names, preventing several macros from being properly
documented.

Also, on defines, we have something like:

	#define foo(a1, a2, a3, ...)			 \
		/* some real implementation */

The prototype part (first line on this example) won't contain
any macros, so no need to apply any regexes on it.

With that, move the apply_transforms() logic to ensure that
it will be called only on functions.
