Every time we work with file-backed memory we construct the paths from the
driver config.  Not only does is that slow, it is also wrong.  If the
configuration changes while a domain with file-backed memory is running, once
the daemon is restarted and the domain is being stopped, we construct the wrong
path to clean up.  And it also makes it more difficult to change that in the
future, for example the patch series which led me to write this patch series:

    https://lists.libvirt.org/archives/list/devel@lists.libvirt.org/message/I6VOQL453JKGKTWVERW5RSBILCKRBEEU/

The patches are maybe split way too much, so feel free to suggest squashing some
together, I'm not opposed to that.

Martin Kletzander (8):
  qemu: Move domain-related functions to qemu_domain
  qemu_domain.h: Change indentation for new functions
  qemu: Change parameters of qemuGetMemoryBackingDomainPath()
  qemu_domain: Add memoryBackingDir to qemuDomainObjPrivate
  qemu_domain: Add qemuDomainSetPrivateMemPath()
  qemu_domain: Set memoryBackingDir in private data upon start
  qemu: Use per-domain private memoryBackingDir for new memory backends
  qemu_domain: Remove unused qemuGetMemoryBackingDomainPath()
