Subject: [PATCH 3/3] ospfd: Support show intra-area network type in 'show ip
ospf route' command
User can now use 'show ip ospf route detail' command to distinguish
intra-area stub network and transit network.
Transit network will be displayed as 'N T prefix ...'.
NOTICE: Json output format has been changed, intra-area stub networks
still has 'N' routeType, transit networks has 'N T' routeType. And
'adv' (means advertise router) change to 'advertisedRouter'.
