The function modifies the context but did not care to restore it back.
If a <seclabel> was used on a disk, the <privateData> would not be
parsed.
Use VIR_XPATH_NODE_AUTORESTORE and add a test case to validate that
everything works.

This caused the live XML to report the 'bridge' type instead of the
'network' type, which is a behavioural regression.
It also breaks 'virsh domif-setlink', 'virsh update-device' and
'virsh domiftune'
This reverts commit 518026e159.

Ports allocated on virtual networks with type=nat|route|open all get
given an actual type of 'network'.
Only ports in networks with type=bridge use an actual type of 'bridge'.
This distinction makes little sense since the virtualization drivers
will treat both actual types in exactly the same way, as they're all
just bridge devices a VM needs to be connected to.
This doesn't affect user visible XML since the "actual" device XML
is internal only, but we need code to convert the data upgrades.

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.

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.

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.

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.

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.
