These are meant to replace the ad-hoc helpers qemuHotplugDiskSourceAttach... and the open-coded version in qemu_command.c for use in command line generation. The functions for preparing for attach of chains unfortunately need to be in qemu_command.c as they use function defined by that file and inclusion hierarchy. In this patch new functions are introduced and subsequent patches then refactor individual parts to use them.
