wireprototypes: move wire protocol response types to new module

We'll be introducing more types as part of wire protocol version 2.
These types are shared between the command handling code (in
wireproto.py) and the protocol/transport code in wireprotoserver.py.
So they need to go in a new module to prevent a cycle.

The types are aliased into the wireproto module, so API compatibility
is preserved.
