When libvirtd is restarted, it checks that each guest tap device is
still attached to the bridge device that the configuration info says
it should be connected to. If not, the tap will be disconnected from
[wherever it is] and connected to [wherever it should be].
The previous code that did this did not account for:
1) the IFLA_MASTER attribute in a netdev's ifinfo will be set to
"ovs-system" for any tap device connected to an OVS bridge, *not*
to the name of the bridge it is attached to.
2) virNetDevRemovePort() only works for devices that are attached to a
standard Linux host bridge. If a device is currently attached to an
OVS bridge, then virNetDevOpenvswitchRemovePort() must be called
instead.
This patch remedies those problems, and adds a couple of information
log messages to aid in debugging any future problem.

This function retrieves the name of the OVS bridge that the given
netdev is attached to. This separate function is necessary because OVS
set the IFLA_MASTER attribute to "ovs-system" for all netdevs that are
attached to an OVS bridge, so the standard method of retrieving the
master can't be used.

Once we called qemuDomainObjEnterRemote to talk to the destination
daemon during a peer to peer migration, the vm lock is released and we
only hold an async job. If the source domain dies at this point the
monitor EOF callback is allowed to do its job and (among other things)
clear all private data irrelevant for stopped domain. Thus when we call
qemuDomainObjExitRemote, the domain may already be gone and we should
avoid touching runtime private data (such as current job info).
In other words after acquiring the lock in qemuDomainObjExitRemote, we
need to check the domain is still alive. Unless we're doing offline
migration.

Starting with QEMU 2.9, encryption convert processing requires
a multi-step process in order to generate an encrypted image from
some non encrypted raw image.
Processing requires to first create an encrypted image using the
sizing parameters from the input source and second to use the
--image-opts, -n, and --target-image-opts options along with inline
driver options to describe the input and output files, generating
two commands such as:
$ qemu-img create -f luks \
--object secret,id=demo.img_encrypt0,file=/path/to/secretFile \
-o key-secret=demo.img_encrypt0 \
demo.img 500K
Formatting 'demo.img', fmt=luks size=512000 key-secret=demo.img_encrypt0
$ qemu-img convert --image-opts -n --target-image-opts \
--object secret,id=demo.img_encrypt0,file=/path/to/secretFile \
driver=raw,file.filename=sparse.img \
driver=luks,file.filename=demo.img,key-secret=demo.img_encrypt0
$
This patch handles the convert processing by running the processing
in a do..while loop essentially reusing the existing create logic and
arguments to create the target vol from the inputvol and then converting
the inputvol using new arguments.
This then allows the following virsh command to work properly:
virsh vol-create-from default encrypt1-luks.xml data.img --inputpool default
where encrypt1-luks.xml would provided the path and secret for
the new image, while data.img would be the source image.

Currently the nwfilter driver does not keep any record of what filter
bindings it has active. This means that when it needs to recreate

drivers. This introduces a hash table recording the virNWFilterBinding
