[Peter Krempa]

v2:
 - fixed uninitialized value usage when reading image header

Peter Krempa (17):

  virsh: Introduce 'dom-fd-associate' for invoking
    virDomainFDAssociate()
  conf: storage_source: Introduce type for storing FDs associated for
    storage
  qemu: Implement qemuDomainFDAssociate
  qemuxml2argvtest: Add support for populating 'fds' in private data
  conf: Add 'fdgroup' attribute for 'file' disks
  qemu: domain: Introduce qemuDomainStartupCleanup
  conf: storage_source: Introduce virStorageSourceIsFD
  qemu: Prepare data for FD-passed disk image sources
  qemu: block: Add support for passing FDs of disk images
  secuirity: DAC: Don't relabel FD-passed virStorageSource images
  security: selinux: Handle security labelling of FD-passed images
  qemu: Prepare storage backing chain traversal code for FD passed
    images
  qemu: driver: Don't allow certain operations with FD-passed disks
  qemu: cgroup: Don't setup cgroups for FD-passed images
  qemu: Enable support for FD passed disk sources
  qemuxml2*test: Enable testing of disks with 'fdgroup'
