Add support for variadic extern functions, as it turns out that you can't just specialize them with declarations. I.e., int a_func(int, ...) is different from int a_func(int, int) even if you only ever call a_func(1,2), etc. This commit is in preperation for moving to correcty variadic extern functions for the c stdlib (like printf, snprintf)
