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
Use the index stored in virStorageSource struct rather than
recalculating it. Currently we'd report proper numbers but that will
change with blockdev.

With -blockdev qemu will not report any useful "device" for the data
returned by 'query-block'. We need to start using the 'qdev' field to do
so in cases when "device" is empty or it does not match the entry name.
This patch adds data for the 'qdev' field into the returned data
structure.
Rather than totalling every entry from 'query-block' for stats provided
by qemuDomainBlocksStatsGather total only stats for known disks. This
will allow to return data for nodenames and qdevs in the same hash so
that we can use them with -blockdev.

Libvirt now tries to preserve all mounts under /dev in qemu namespaces.
