3b5181b731 qemu: domain: Regenerate alias for the TLS x509 credential object
When restarting libvirt would previously lose the alias of the x509
certificate object. Upon unplug we would then not delete the
corresponding objects.

Restore the alias if we know it should be there.

Luckily for disks we don't support encrypted TLS environment, so there's
no need to regenerate the 'secret' alias for decryption.

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.

7c6b00b8fe qemu: domain: Regenerate auth/enc secret aliases when restoring status XML
Previously we did not store the aliases but rather re-generated them
when unplug was necessary. This is very cumbersome since the knowledge
when and which alias to use needs to be stored in the hotplug code as
well.

While this patch will not strictly improve this situation since there
still will be two places containing this code it at least will allow to
remove the mess from the disk-unplug code and will prevent introducing
more mess when adding blockdev support.

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.
