[PATCH 2/4] qemu_domainjob: job funcitons moved out of `qemu_domain`

We move functions `qemuDomainObjPrivateXMLParseJob` and `qemuDomainObjPrivateXMLFormatJob` to `qemu_domainjob`. To make this happen, corresponding changes in their parameters were made, as well as they were exposed to be used in `qemu_domain` file.
