[libvirt] [PATCH 04/11] conf: Use getParseOpaque() in virDomainObjSetDefTransient

[Marc Hartmayer]

This allows the QEMU driver to use the originally used QEMU
capabilities for copying the domain. It avoids the usage of a possible
changed QEMU capability as virQEMUCapsCacheLookup might return a
different QEMU capability than used before (for example when during
the job the QEMU binary has been replaced virQEMUCapsCacheLookupCopy
will invalidate the originally used QEMU capability).

For other drivers @parseOpqaue will still be NULL, because
xmlopt->privateData.getParseOpaque is currently only implemented for
the QEMU driver.
