[libvirt] [PATCHv5 00/28] Refactor changing of domain disk source

[Peter Krempa]

v4 wasn't reviewed, but recent patches caused pretty serious conflicts
thus I'm posting a rebased version.

Note that one of the patches was already pushed as a part of a different series.

This series is also a preparation for fixing issue with libvirt
not setting correct permissions on gluster volumes.

Peter Krempa (28):
  storage: Implement virStorageFileCreate for local and gluster files
  qemu: Don't propagate whole disk definition into qemuDomainGetImageIds
  qemu: Add helper to initialize storage file backend with correct
    uid/gid
  storage: file: Tolerate NULL src when uninitializing the backend
  conf: Don't output seclabels for backingStore elements
  storage: Move readonly and shared flags to disk source from disk def
  util: storagefile: Add deep copy for struct virStorageSource
  util: storage: Add function to transfer config parts to new chain
    element
  util: storage: Copy parent's disk metadata to backing chain elements
  util: cgroup: Add helper to convert device mode to string
  qemu: cgroup: Add functions to set cgroup image stuff on individual
    imgs
  qemu: cgroup: Setup only the top level disk image for read-write
    access
  locking: Add APIs to lock individual image files
  security: Introduce APIs to label single images
  security: selinux: Implement per-image seclabel restore
  security: selinux: Implement per-image seclabel set
  security: DAC: Implement per-image seclabel restore
  security: DAC: Implement per-image seclabel set
  security: AppArmor: Implement per-image seclabel restore
  security: AppArmor: Implement per-image seclabel set
  util: storage: Make virStorageFileChainLookup more network storage
    aware
  util: storage: Return complete parent info from
    virStorageFileChainLookup
  qemu: blockcopy: Use the mirror disk source to label the files
  qemu: block: Properly track disk source while pivotting to new image
  qemu: snapshot: Improve approach to deal with snapshot metadata
  qemu: Refactor qemuDomainPrepareDiskChainElement
  qemu: snapshot: Refactor image labelling of new snapshot files
  qemu: snapshot: Use storage driver to pre-create snapshot file
