hnbgw: Bring all parts together
We now have the RUA and SUA parts interconnected by the
context ID mapper, and should be able to pass messages back and forward
between both sides.
Unfortunately this touches a bit of everything, but the structures are
all still very much in flux. Hopefully they will start to stabilize at
some point soon...
