  Modified files:
    sys/sys              mutex.h 
    sys/netinet          ip_input.c 
  Log:
  Rename NET_PICKUP_GIANT() to NET_LOCK_GIANT(), and NET_DROP_GIANT()
  to NET_UNLOCK_GIANT().  While they are used in similar ways, the
  semantics are quite different -- NET_LOCK_GIANT() and NET_UNLOCK_GIANT()
  directly wrap mutex lock and unlock operations, whereas drop/pickup
  special case the handling of Giant recursion.  Add a comment saying
  as much.
  
  Add NET_ASSERT_GIANT(), which conditionally asserts Giant based
  on the value of debug_mpsafenet.
