VMs with hardcoded platform network devices are forced to use old
style '-net nic' command line config. Current we use qemu's vlan
option to hook this with the '-netdev' host side of things.
However since qemu 1.2 there is '-net nic,netdev=X' option for
explicitly referencing a netdev ID, which is more inline with
typical VM commandlines, so let's switch to that

Now that we have one place that sets up all disk-related objects to
qemuBlockStorageSourceAttachDataPtr we can easily reuse the data in the
command-line formatter by implementing a worker which will convert the
data.
A huge advantage is that it will be way easier to integrate this with
-blockdev later on.

In commit 8bebb2b735 I've refactored how the detach of disk with a
managed persistent reservations object is handled. After the commit if
any disk with a managed PR object would be removed libvirt would also
attempt to remove the shared 'pr-manager-helper' object potentially used
by other disks.
Thankfully this should not have practical impact as qemu should reject
deletion of the object if it was still used and the rest of the code is
correct.
Fix this by removing the disk from the definition earlier and checking
if the shared/managed pr-manager-helper object is still needed.
This basically splits the detach code for the managed PR object from the
unmanaged ones. The same separation will follow for the attachment code
as well as it greatly simplifies -blockdev support for this.

detach is semi-synchronous (old virDomainDetachDeviceFlags()) or
