Re: [libvirt] [PATCH 3/8] driver: introduce a driver method for probing default URIs

Currently the virDrvConnectOpen method is supposed to handle both opening an explicit URI and auto-probing a driver if no URI is given. Introduce a dedicated virDrvConnectURIProbe method to enable the probing functionality to be split from the driver opening functionality. It is still possible for NULL to be passed to the virDrvConnectOpen method after this change, because the remote driver needs special handling to enable probing of the URI against a remote libvirtd daemon.
