In the past, the MTU of libvirt virtual network bridge devices was
implicitly set by setting the MTU of the "dummy tap device" (which was
being added in order to force a particular MAC address from the
bridge). But the dummy tap device was removed in commit ee6c936fbb
(libvirt-6.8.0), and so the mtu setting in the network is ignored.
The solution is, of course, to explicitly set the bridge device MTU
when it is created.
Note that any guest interface with a larger MTU that is attached will
cause the bridge to (temporarily) assume the larger MTU, but it will
revert to the bridge's own MTU when that device is deleted (this is
not due to anything libvirt does; it's just how Linux host bridges
work).

managed='no' on an <interface> allows an unprivileged libvirt to use a
pre-created tap/macvtap device that libvirt has permission to
open/read/write, but no permission to modify (i.e. set the MTU or MAC
address). But when the XML had an <mtu size='blah'/> setting (which
was put there in order to tell the *guest* OS what MTU to set for the
emulated device at the other end of the tap) we were attempting to set
the MTU of the tap device on the host, paying no attention to the
setting of 'managed'. That would of course end in failure.
This patch only sets the MTU if managed='no' is *not* set (so, if it
is 'yes', or just not set at all).
Note that MTU of the tap is also set when connecting the tap to a
bridge device, but managed='no' is only allowed for <interface
type='ethernet'>, which would never attach to a bridge anyway, so we
don't need the check there.

'rules' syntax replaces the only/except syntax with which it is
mutually exclusive. In some cases the 'rules' syntax is more readable
than the 'only/except' equivalent, in some cases it is not.
The idea behind this conversion is to introduce an explicit env variable
controlling the 'allow_failure' attribute which would then be attached
to a broken build job which would in turn result in a soft failure.
Such behaviour is not possible to achieve with the older 'only/except'
syntax.

'extends' is slightly more readable and definitely more flexible in

The main reason for this patch though is that the next patch converts

So far we assumed that any vhostuser interface is plugged into an
OVS bridge and thus 'ovs-vsctl' exists. But this is not always
true. In testing scenarios it is possible to create a vhostuser
interface with this tool dpdk-testpmd (part of dpdk RPM) which
creates/connects to UNIX socket needed for vhostuser. Of course,
since there is no OVS then there is no interface name in which
case virNetDevOpenvswitchGetVhostuserIfname() should return 0.
The rest of APIs that assume OVS are not 'fixed' because we still
want them to fail (e.g. getting statistics, plugging interface
into an OVS bridge, unplugging it from an OVS bridge, ...).
The only API that is fixed is
virNetDevOpenvswitchGetVhostuserIfname() because it is called
explicitly when starting a guest (and callers are okay if no name
was found).
The other way to fix this bug seems to be to simply require
'ovs-vsctl' on spec file level, but that is too heavy gun given
that vhostuser is used by a small set of our users (assumption
made on requirements for vhostuser). Also, this way would drag in
yet another dependency for all users (even those who want minimal
libvirt).

The bridge reattach functionality in this function should be called
for interface types other than just type='network', so make it
callable for any type - it just becomes a NOP for types where no
action is needed.
In the case of <interface type='network'> we need to create a port in
the network driver, and for both type='network and type='bridge' we
need to reattach the bridge device (note that
virDomainNetGetActualBridgeName() gets the bridge name from the
appropriate (and different!) location for either type of interface).
All other interfaces currently require no action.
modifying callers of this function to actually call it for all
interface types is in the next patch. For now the behavior should be
identical pre and post-patch.
(NB: the conn argument can now legitimately be NULL, so we need to
change the ATTRIBUTE_NONNULL() directive for the function's
declaration - I noticed when making this change that argument 3 (the
NetDefPtr) could never be NULL, so I added ATTRIBUTE_NONNULL(3) while
removing ATTRIBUTE_NONNULL(1) (conn)).

dnsmasq usually prints out a version string like this:
Dnsmasq version 2.82 [...]
but a user reported that the build of dnsmasq included with pihole has
a version string like this:
Dnsmasq version pi-hole-2.81 [...]
We parse the dnsmasq version number to figure out if the dnsmasq
binary supports certain features. Since we expect the version number
(and it must be only numbers!) to start on the first non-space after
the string "Dnsmasq version", we fail to parse this format of the
version string.
Rather than spending a bunch of time trying to get pihole to change
that, we can just make our parsing more permissive - after searching
for "Dnsmasq version", we'll skip ahead to the first decimal digit,
rather than just the first non-space.
(NB: The features we're checking for purely by looking at version
number have been in all releases of dnsmasq since at least 2012, so we
could actually just remove the reading of the version number
completely. However it's possible (although *highly* unlikely)
that some new feature would be added to dnsmasq in the future and we
would need to add that code back.)
