  SVN rev 196632 on 2009-08-28 21:14:04Z by rwatson
  
  Merge r196559 from head to stable/8:
  
    Add IFNET_HOLD reserved pointer value for the ifindex ifnet array,
    which allows an index to be reserved for an ifnet without making
    the ifnet available for management operations.  Use this in if_alloc()
    while the ifnet lock is released between initial index allocation and
    completion of ifnet initialization.
  
    Add ifindex_free() to centralize the implementation of releasing an
    ifindex value.  Use in if_free() and if_vmove(), as well as when
    releasing a held index in if_alloc().
