[libvirt PATCH 3/4] remote: remove probing logic from virtproxyd dispatcher

[Daniel P. Berrangé]

Now that the remote driver itself can probe for listening sockets /
running daemons, virtproxyd doesn't need to probe URIs itself. Instead
it can just delegate to the remote driver.

- * drivers are in separate daemons. Thus when we get a NULL
- * URI we need to simulate probing that virConnectOpen would
- * previously do. We use the existence of the UNIX domain
- * socket as our hook for probing.
- *
- * This assumes no stale sockets left over from a now dead
- * daemon, but that's reasonable since libvirtd unlinks
- * sockets it creates on shutdown, or uses systemd activation
- *
- * We only try to probe for primary hypervisor drivers,
- * not the secondary drivers.
