Nearly every part of the code that ever handles a full backend structure has historically done it using a pair of pointer variables, one pointing at a constant struct full of function pointers, and the other pointing to a 'void *' state object that's passed to each of those. While I'm modernising the rest of the code, this seems like a good time to turn that into the same more or less type-safe and less cumbersome system as I'm using for other parts of the code, such as Socket, Plug, BinaryPacketProtocol and so forth: the Backend structure contains a vtable pointer, and a system of macro wrappers handles dispatching through that vtable.
