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.

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.

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.
