Re: [libvirt] [PATCH 0/4] test_driver: implement virDomainSaveImageGetXMLDesc and virDomainSaveImageDefineXML

While implementing virDomainSaveImageGetXMLDesc and virDomainSaveImageDefineXML for the test driver, I realized that there exists already code for saving and loading test images which can be reused. However, it needed to be extracted from testDomainSaveFlags and testDomainRestoreFlags into separate functions. The new functions are inspired by the corresponding QEMU driver code where e.g. qemuDomainSaveImageOpen serves as a helper used by other functions. This series of patches initially extracts the code mentioned above into separate functions and then provides the test driver with implementations for virDomainSaveImageGetXMLDesc and virDomainSaveImageDefineXML which make use of the newly introduced functions.
