Renato Westphal 75aa7aa135 isisd: add abiliy to compute the reverse shortest path tree 
RFC 7490 says:
 "The reverse SPF computes the cost from each remote node to root. This
  is achieved by running the normal SPF algorithm but using the link
  cost in the direction from the next hop back towards root in place of
  the link cost in the direction away from root towards the next hop".

Support for reverse SPF will be necessary later as it's one of the
algorithms used to compute R-LFA/TI-LFA repair paths.
