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.

Historically we have used a bare lxc:/// URI for connecting to LXC. This
is different from our practice with QEMU, UML, Parallels, Libxl, BHyve
and VirtualBox drivers, which all use a path of '/system' or '/session'
or both.
By making LXC allow '/system', we have fully standardized on the use of
either '/system' or '/session' for all the stateful drivers that run
inside libvirtd.
Support for lxc:/// is of course maintained for back-compat.

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.

Both pcie-to-pci-bridge and dmi-to-pci-bridge can be used to
create a traditional PCI topology in a pure PCIe guest such as
those using the x86_64/q35 or aarch64/virt machine type;
however, the former should be preferred, as it doesn't need to
obey limitation of real hardware and is completely
architecture-agnostic.

Using the 'require' value for the 'policy' attribute indicates
that the guest will have the feature so the host CPU does not
need to support it if the hypervisor can emulate it.
E.g. 'x2apic' is emulated by QEMU even if the host does not support it:
