Those are fairly trivial to reimplement, but any non-trivial user of sd-bus is likely to need them. So let's expose them to save everyone the trouble. I'm keeping the internal functions and making the public ones thin wrappers, because for the internal uses we don't need the additional asserts, and also we can't expose _pure_ annotation easily, and dropping it would likely make the compiled code a bit less efficient.
