In a recent change b932ed69: "virt-aa-helper: resolve yet to be created

cases where the file being last element of the path was the actual link.
In the case of the last element being the symlink realpath can (and shall)
be called on the full path that was passed.
Examples would be zfs/lvm block devices like:
<disk type='block' device='disk'>
<driver name='qemu' type='raw'/>
<source dev='/dev/mapper/testlvm-testvol1'/>
<target dev='vdd' bus='virtio'/>
</disk>
With the target being:
/dev/mapper/testlvm-testvol1 -> ../dm-0
That currently is rendered as
"/dev/mapper/testlvm-testvol1" rwk,
but instead should be (and is with the fix):
"/dev/dm-0" rwk,

Commit b4c2ac8d56 made a false assumption that IOMMU support necessary
for an mdev device to be assigned to a VM. Unlike direct PCI assignment,
IOMMU support is not needed for mediated devices, as the physical parent
device provides the isolation, therefore, simply checking for VFIO
presence is enough to successfully start a VM.
Luckily, this issue is not serious, since as of yet, libvirt mandates
mdevs to be pre-created prior to a domain's launch - if it is,
everything does work smoothly even with IOMMU disabled, because the
parent device will ensure the iommu groups we try to access exist.
However, if there are *no* IOMMU groups yet, thus no mdev exists yet, one
would see the following error:
"unsupported configuration: Mediated host device assignment requires VFIO
support"
The error msg above is simply wrong and doesn't even reflect the IOMMU
reality, so after applying this patch one would rather see the following
error in such case instead:
"device not found: mediated device '<UUID>' not found"

What one currently gets is:
failed to read '/sys/bus/mdev/devices/<UUID>/mdev_type/device_api': No
such file or directory
This indicates that something is missing within the device's sysfs tree
which likely might be not be the case here because the device simply
doesn't exist yet. So, when creating our internal mdev obj, let's check
whether the device exists first prior to trying to verify the
user-provided model within domain XML.

Reloading of the nwfilter driver is stuck waiting for a write lock, which
already has a reader (from qemuDomainCreateXML) in the critical section.
Since the reload occurs in the context of the main event loop thread,
libvirtd becomes deadlocked. The deadlock can be avoided by offloading
the reload work to a thread.

The bhyve driver crashes in bhyveBuildNetArgStr() when
network interface model is not defined. As it has to be provided
explicitly, add a check to report an error if it's missing.

Clang 6.0.0 complains when initializing structure with { NULL }:

This time around it's not enough to just pick the latest commit,
because with aed87bb2aa6ed83b49574eb982e3bdd4c36acf17 keycodemapdb
renamed the 'rfb' keycode to 'qnum' and we need to accept the new
name while maintaining backwards compatibility.

When validating a device XML config we check if user provided
alias is unique. We do this by maintaining a hash table of device
aliases as we iterated over all devices defined for the domain.
However, it may happen that what appears as two devices in domain
XML is in fact just one interface in hypervisor. We can assume
libvirt generated aliases to be unique and thus really check user
provided ones only.

For some weird reason this function is getting live and
persistent def for domain but then accesses vm->def and
vm->newDef directly. This is rather unsafe as we can be
accessing NULL pointer.
