ospfd: Update Traffic Engineering support

These patches update original code to RFC3630 (OSPF-TE) and add support of
RFC5392 (Inter-AS v2) & RFC7471 (TE metric extensions) and partial support
of RFC6827 (ASON - GMPLS).

* ospfd/ospf_dump.[c,h]: Add new dump functions for Traffic Engineering
* ospfd/ospf_opaque.[c,h]: Add new TLV code points for RFC5392
* ospfd/ospf_packet.c: Update checking of OSPF_OPTION
* ospfd/ospf_vty.[c,h]: Update ospf_str2area_id
* ospfd/ospf_zebra.c: Add new function ospf_interface_link_params() to get
  Link Parameters information from the interface to populate Traffic
  Engineering metrics
* ospfd/ospfd.[c,h]: Update OSPF_OPTION flags (T -> MT and new DN)
* ospfd/ospf_te.[c,h]: Major modifications to update the code to new
  link parameters structure and new RFCs
