* conf: Add support for keeping TPM emulator state
Currently, swtpm TPM state file is removed when a transient domain is
powered off or undefined. Add per-TPM emulator option ``persistent_state``
for keeping TPM state.

an usage name which would not pass the XML validation. Relax the requirement
to make such XMLs valid.
* virnetdevopenvswitch: Various improvements
The code that handles ``<interface type='vhostuser'/>`` was given various
improvements. So far, libvirt assumed vhostuser interfaces are handled
exclusively by OpenVSwitch and refused to start a guest if it was not so.
Now a guest can be started successfully even if the interface is created by
some other tool (e.g. ``dpdk-testpmd``). Also, the code that detects the
interface name was adapted to new versions of OpenVSwitch and thus can
detect name more reliably.
* qemu: Report guest disks informations in ``virDomainGetGuestInfo``
Libvirt is now able to report disks and filesystems from the guest's
perspective (using guest agent). And with sufficiently new guest agent
(5.3.0 or newer) the API also handles disks on CCW bus.

libvirt version to 7.0.0 will not be affected by this change.
* qemu: Don't cache NUMA caps
``virsh capabilities`` contains ``<topology/>`` section which reports NUMA
topology among with amount of free hugepages per each NUMA node. However,
these amounts were not updated between calls.
* networkGetDHCPLeases: Handle leases with infinite expiry time
Since libvirt-6.3.0 it is possible to configure expiry time for DHCP
leases. If the expiry time was infinite then ``virsh net-dhcp-leases``
and NSS plugins refused to work.
* qemu: Don't prealloc mem for real NVDIMMs
If a real life NVDIMM is assigned to a guest via ``<memory model='nvdimm'/>``
then QEMU is no longer instructed to preallocate memory
for it. This prevents unnecessary wear on the NVDIMM.
* network: Introduce mutex for bridge name generation
When new libvirt network is defined or created and the input XML does not
contain any bridge name, libvirt generates one. However, it might have
happened that the same name would be generated for different networks if
two or more networks were defined/created at once.
