[libvirt] [v4 4/5] virsh: Add vshSuspendTargetCompleter

[Tomas Meszaros]

vshSuspendTargetCompleter returns targets available for suspend.

This completer can be used for the command option completion
(for dompmsuspend, etc.).

 virsh # dompmsuspend --target <TAB>
  mem      disk    hybrid
 virsh # dompmsuspend --target h<TAB>
 virsh # dompmsuspend --target hybrid

---
v2
* label cleanup renamed to error
* vshSuspendTargetCompleter added to opts_dom_pm_suspend

v3
* removed useless if
* used virStringFreeList() instead of iteration

v4
* rewritten using virStringSplit()
