Log message:
	Wrap up the context functions in functions prefixed with Uucontext__
	in particular so that systems that have the functions in some versions
	but not others do not have a name clash when we provide them.
	In particular, Darwin got the functions in 10.5.
	Wrapping a vararg function for which there is no version that takes
	a va_list (counterexample: sprintf/vsprintf) is problematic and
	we have a hardcoded limit (makecontext).
	
	And of course rename our implementations for systems without (Darwin <10.5, OpenBSD).
