    ip: add selector_is_address(selector, address)
    
    as in:
      sa = selector_from_address()
      selector_eq(selector, &sa)
    subnetisaddr() doesn't check ports and is clueless about protools.

    ip: ip_range cleanups
    
    - sprinkle range_is_unset()
    
    - replace iprange_bits(lo,hi) with range_significant_bits(range)
    
      Fixes: ??? this really should use ip_range rather than a pair of
      ip_address values
    
    - update tests
