py3: provide (del|get|has|set)attr wrappers that accepts bytes
These functions will be imported automagically by our code transformer.
getattr() and setattr() are widely used in our code. We wouldn't probably
want to rewrite every single call of getattr/setattr. delattr() and hasattr()
aren't that important, but they are functions of the same kind.
