sshpeer: make "instance" a function The API is that peer modules must provide an "instance" symbol that is callable to return a peer. Making "instance" a function instead of an alias to "sshpeer" makes it easier to monkeypatch the "sshpeer" type. It will also make it possible to turn instance() into a factory function of sorts that returns different types based on connection properties.
