d451575bb1 qemu: domain: Add field for storing node name for copy-on-read
The copy-on-read feature is expressed by adding a new node layer in
qemu when using -blockdev. Since we will keep these per-disk (as opposed
to per storage source) we need to store the appropriate node names in
the disk definition.

716c46178a qemu: Add field to store QOM path of a disk in private data
When using -blockdev you need to use the qom path to refer to the disk
fronends. Add means for storing the path and getting it after restart.

e436881b02 qemu: domain: Add infrastructure to generate block node names
Node names for block objects in qemu need to be unique for an instance
of the qemu process. Add a counter to generate objects sequentially and
store it in the status XML so that we can restore it.

The helpers added allow to create new node names and reset the counter
after the VM process terminates.

1f1aa21cb9 qemu: domain: Store and restore TLS object alias of a disk
Libvirt uses the stored alias to detach the TLS x509 object on disk
unplug. As the alias was not stored, the object would not be detached
if unplugging disks after libvirtd restart.

931144858f qemu: Figure out nodeset bitmap size correctly
The current private XML parsing code relies on the assumption
that NUMA node IDs start from 0 and are densely allocated,
neither of which is necessarily the case.

Change it so that the bitmap size is dynamically calculated by
looking at NUMA node IDs instead, which ensures all nodes will
be able to fit and thus the bitmap will be parsed successfully.

Update one of the test cases so that it would fail with the
previous approach, but passes with the new one.
