The current qemu driver code for changing bandwidth on a NIC first asks
the network driver if the change is supported, then changes the
bandwidth on the VIF, and then tells the network driver to update the
bandwidth on the bridge.
This is potentially racing if a parallel API call causes the network
driver to allocate bandwidth on the bridge between the check and the
update phases.
Change the code to just try to apply the network bridge update
immediately and rollback at the end if something failed.

When (un)plugging an interface into a network, the 'plugged'
and 'unplugged' operations are invoked in the hook script.
The data provided to the script contains the network XML, the
domain XML and the domain interface XML. When we strictly split the
drivers up this will no longer be possible and thus breakage is
unavoidable. The hook scripts are not considered to be covered by the
API guarantee so this is OK.
To avoid existing scripts taking the wrong action, the existing
operations are changed to 'port-created' and 'port-deleted'
instead. These will receive the network XML and the network port
XML.

The domain conf actual network def stores a <class id='3'/> element
separately from the <bandwidth>. The class ID should really just be
an attribute on the <bandwidth> element. We can't change existing
XML, and this isn't visible to users since it is internal XML only.
When we expose the new network port XML to users though, we should
get the design right.

If libvirt receives DISCONNECTED event and prDaemonRunning is set
to false, and qemuDomainRemoveDiskDevice() is performing in the
meantime, then qemuDomainRemoveDiskDevice() will fail to remove
pr-helper object because prDaemonRunning is false. But removing
that check from qemuHotplugRemoveManagedPR() is not enough,
because after removing the object through monitor the
qemuProcessKillManagedPRDaemon() is called which contains the
same check. Thus the pr-helper process might be left behind.
