Avoid the need for the drivers to explicitly check for a NULL path by

Now that the legacy Xen driver has been dropped, we no longer need to

Ensuring that we don't call the virDrvConnectOpen method with a NULL URI

Declare what URI schemes a driver supports in its virConnectDriver
struct. This allows us to skip trying to open the driver entirely
if the URI scheme doesn't match.
Signed-off-by: NDaniel P. Berrangé <berrange@redhat.com>

Add a localOnly flag to the virConnectDriver struct which allows a
driver to indicate whether it is local-only, or permits remote
connections. Stateful drivers running inside libvirtd are generally
local only. This allows us to remote the check for uri->server != NULL
from most drivers.
Signed-off-by: NDaniel P. Berrangé <berrange@redhat.com>

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.
Signed-off-by: NDaniel P. Berrangé <berrange@redhat.com>

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.

Up until now we have only formatted non-default GIC versions on
the command line, in order to maintain compatibility with older
QEMU versions that didn't implement the gic-version option to
begin with; however, doing so is entirely unnecessary for newer
QEMU versions, where the option is available. Moreover, having
the GIC version formatted on the command line at all times
ensures that QEMU changing its own defaults doesn't affect the
ABI of libvirt guests.

A few test cases are removed to avoid extra churn. It doesn't
matter for coverage, as those scenarios are already covered by
other parts of the test suite.

This patch is better viewed with 'git show -w'.
