ospfd: avoid exhausting memory with OSPF vertices (BZ#476)
This was found in scale testing at OSR; ospfd is adding the same link over and over again to the SPF tree. This fix prevents the resulting memory corruption from happening and adds a debug message to track occurence of this issue and/or confirm a proper fix. (This version was improved by Scott Feldman over the earlier RFC.) * ospfd/ospf_spf.c: (ospf_spf_add_parent) loop over existing vertices and refuse to add duplicates.
