wireprotoserver: add version to SSH protocol names (API)
We recently introduced version 2 of the SSH protocol. Like we
did for the peer, we will need to differentiate version 1 and 2
of the server. So, we add version components to the advertised
name of the protocol handler.
Nothing in core looks for the old value. But an extension may.
.. api::
SSH protocol handler now advertises its name internally as
"ssh-v1" instead of "ssh."
