Historically we have used a bare xen:/// URI for connecting to the legacy Xen driver. The new libxl Xen driver follows the new practice of allowing '/system' as a path, as well as bare '/' for compat with the old Xen driver. This documents xen:///system as the preferred format for Xen, leaving xen:/// as an undocumented feature just for back-compat. Signed-off-by: Daniel P.

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.
