    afs: provide cache eviction statistics
    
    In order to identify cache managers that need larger cache partitions,
    provide new statistics on cache evictions:
    
    - internal run & sleep times for the CacheTruncateDaemon housekeeper
    - a cumulative count of evicted blocks since cache manager
      initialization
    - a count of evicted blocks for the current 1 hour recording interval
    - a table of counts of evicted blocks for each of the previous (up to)
      24 hours
    
    All blocks are of size 1KiB by OpenAFS convention.
    
    The statistics are available via a new collection (3) for the existing
    xstat_cm_test utility:
    
    $ xstat_cm_test localhost -onceonly -collID 3
    
    Starting up the xstat_cm service, no debugging, one-shot operation
