Issuing the token sends the hub its new peer, and the hub applies it on
its own time; a bus dialled before then timed out naming the bus. The
first tunnel now waits for a handshake with the hub, and says so in the
tunnel's words when there is none (novox/hq ADR 0169).
nox-mesh-host key makes the tunnel key, or reads the one made, and
prints its public half for the token to be issued for. enrol with a
token that carries a tunnel takes that key, refuses another, writes
mesh0 with the hub as its one peer and starts it, then reaches the bus
over it (novox/hq ADR 0169). Tokens without a tunnel enrol as before.
