[OSPF] Revised OSPF HMAC SHA Authentication Draft

Hi,

We have updated the OSPF HMAC-SHA authentication draft with the comments
that we received on the list and offline.

The updated version has a short section which discusses backwards
compatibility, similarities and differences from using MD5 (which is
explained in Section 5 of 2328), etc.

Please let us know if there are further modifications desired.

Cheers,
Manav, Vishwas, et al.
