* re-write cm_Analyze to make better use of the known volume
  status.  VL_Server queries cannot result in CM_ERROR_ALLOFFLINE
  messages.

* renamed cm_CheckBusyVolumes to cm_CheckOfflineVolumes.
  busy volumes will be reset to srv_non_busy by the function
  but there is no mechanism for querying the busy state other
  than by attempting to access the resource.

* cm_Analyze will query the state of an offline volume before
  deciding whether or not to retry when all volume instances
  are offline.
