3eb151ddfd virNWFilterBindingDefParse: Properly use virXMLParse
Fetch the XPath context and validate the node by using virXMLParse's
features.

This allows to completely remove virNWFilterBindingDefParseNode as
all callers now properly validate the root element name and have a XPath
context handy.

thing, except for one XPath query.

Factor out the common code into a helper and bring it up to modern

0c5378bc07 util: xml: Expose all arguments of virXMLParseHelper in virXMLParse macro
The generic helper also has helper code to validate the root element and
create an XPath context. Many places in the code duplicate code for
doing these operations.

Extend the helper to provide all arguments and fix all callers.

In many cases this patch refactors the passing of the 'validate'
field into a separate variable to avoid quirky looking arguments.

92f7aafced qemu: tpm: Remove TPM state after successful migration
This patch 'fixes' the behavior of the persistent_state TPM domain XML
attribute that intends to preserve the state of the TPM but should not
keep the state around on all the hosts a VM has been migrated to. It
removes the TPM state directory structure from the source host upon
successful migration when non-shared storage is used. Similarly, it
removes it from the destination host upon migration failure when
non-shared storage is used.

a2fe32a71b virpcivpd: reduce errors in log due to invalid VPD
Sadly some devices provide invalid VPD data even with fully updated
firmware. Former hardning like 600f580d "PCI VPD: Skip fields with
invalid values" have already helped for those to some extent.
But if one happens to have such a device installed in the system,
despite all other things working properly the log potentially
flooded with messages like:
  internal error: The keyword is not comprised only of uppercase ASCII
  letters or digits
  internal error: A field data length violates the resource length boundary.

The user can't do anything about it to change that, they will be there on
any libvirt restart and potentially distract from other more important
issues.

Since the vpd decoding is implemented rather resilient (if parsing fails
all goes on fine, the respective device just has no VPD data populated
eventually) we can lower those from virReportError(VIR_ERR_INTERNAL_ERROR
to just VIR_INFO. If needed for debugging people can set the level
accordingly, but otherwise we would no more fill the logs with errors
without a strong reason.

virt-aa-helper: allow common riscv64 loader paths
Riscv64 usually uses u-boot as external -kernel and a loader from
the open implementation of RISC-V SBI. The paths for those binaries
as packaged in Debian and Ubuntu are in paths which are usually
forbidden to be added by the user under /usr/lib...

People used to start riscv64 guests only manually via qemu cmdline,
but trying to encapsulate that via libvirt now causes failures when
starting the guest due to the apparmor isolation not allowing that:
   virt-aa-helper: error: skipped restricted file
   virt-aa-helper: error: invalid VM definition

Explicitly allow the sub-paths used by u-boot-qemu and opensbi
under /usr/lib/ as readonly rules.

41eb0f446c rpc: fix memory leak in virNetServerClientNew and virNetServerProgramDispatchCall
In virNetServerProgramDispatchCall, The arg is passed as a void*
and used to point to a certain struct depended on the dispatcher,
so I think it's the memory of the struct's member that leaks and
this memory shuld be freed by xdr_free.

In virNetServerClientNew, client->rx is assigned by invoking
virNetServerClientNew, but isn't freed if client->privateData's
initialization failed, which leads to a memory leak. Thanks to
Liang Peng's suggestion, put virNetMessageFree(client->rx) into
virNetServerClientDispose() to release the memory.
