The libvirt created linux bridge has a configurable value "delay",
the default value is "0", but it will not take effect. That's because
kernel has a minimum value for linux bridge. Add some explanation
about it in the document.

This patch makes it possible to manually specify which VFIO variant
driver to use for PCI hostdev device assignment, so that, e.g. you
could force use of a VFIO "variant" driver, with e.g.
<driver model='mlx5_vfio_pci'/>
or alternately to force use of the generic vfio-pci driver with
<driver model='vfio-pci'/>
when libvirt would have normally (after applying a subsequent patch)
found a "better match" for a device in the active kernel's
modules.alias file. (The main potential use of this manual override
would probably be to work around a bug in a new VFIO variant driver by
temporarily not using that driver).

The long-deprecated use of <driver name='vfio|xen|kvm'/> in domain xml
for <hostdev> devices was only ever necessary during the period when
libvirt (and the Linux kernel) supported both VFIO and "legacy KVM"
styles of hostdev device assignment for QEMU. This became pointless
many years ago when legacy KVM device assignment was removed from the
kernel, and support for that style of device assignment was completely
disabled in the libvirt source in 2019 (commit
v5.6.0-316-g2e7225ea8c).
Nevertheless, there were instances of <driver name='vfio'/> in the
unit test data that were then (unnecessarily) propagated to several
more tests over the years. This patch cleans out those unnecessary
explicit settings of driver name='vfio' in all QEMU unit test data,
proving that the attribute is no longer (externally) needed. (A later
patch which adds a 2nd attribute to the <driver> element will include
a test case that explicitly exercises the driver name attribute).

This patch adds new elements <title> and <description> to the Network XML.
- The <title> attribute holds a short title defined by the user and
cannot contain newlines.
- The <description> attribute holds any documentation that the user
wants to store.
- Schema definitions of <title> and <description> have been moved from
domaincommon.rng to basictypes.rng for use by network and future objects.
- Added Network XML parser logic for the above.
