'certificate' subelements. Another options would require us to stop

If a domain is configured to create a macvtap/macvlan but the
target link already exists, startup fails (as expected) with:
error: error creating macvtap interface test@eth0 (52:54:00:d9:0b:db): File exists
Okay, we could make that error message better, but that's not the
point. Since this error originated while generating cmd line
(the caller is qemuProcessStart(), transitively), the cleanup
after failed start is performed (qemuProcessStop()). Here,
virNetDevMacVLanDeleteWithVPortProfile() is called which removes
the macvtap interface we did not create (as it made us fail in
the first place).
Therefore, we need to track which macvtap/macvlan interface was
created successfully and remove only those.
You'll notice that only qemuProcessStop() has the new check. For
the (failed) hotplug case (qemuDomainAttachNetDevice()) this
function is already in place (the @iface_connected variable), or
not needed (qemuDomainRemoveNetDevice() - we're removing an
interface that was already attached to QEMU).

In virsh, we have this convenient domif-setlink command, which is

setting link state of given guest NIC. It does so by fetching
corresponding <interface/> XML snippet and either putting <link

attribute to desired value. The XML is then fed into the update
API.
There's, however, a small bug in detecting the pre-existence of
the element and its attribute. The code looks at "link"
attribute, while in fact, the attribute is called "state".
