largefiles: test interaction between largefiles and vanilla clients and servers

This reintroduces tests for the case described by issue3066, among others:
- vanilla clients and servers should still be able to talk to largefiles
  clients and servers about vanilla repos
- vanilla clients should not attempt to clone largefiles repos over http and
  should report a useful error message (issue3066; this appears to work
  correctly)
- vanilla clients should not attempt to clone largefiles repos over ssh, again
  with a useful error message
- largefiles clients should not attempt to push largefile changes to vanilla
  servers
