From 8edf2361f9c4bd745a1249db3f66dfc079dd2ca1 Mon Sep 17 00:00:00 2001

Subject: Cleaned up handling of interface patterns:

   o  Parsing of interface patterns moved to generic code,
      introduced this_ipatt which works similarly to this_iface.
   o  Interface patterns now support selection by both interface
      names and primary IP addresses.
   o  Proto `direct' updated.
   o  RIP updated as well, it also seems the memory corruption
      bug there is gone.
