zebra: justify some IPv6 ND RA timers wrt RFC
There was a regression introduced with the previous commit: "ipv6 nd home-agent-lifetime 1800000" appeared by default in every interface section of running-config, although this command is invalid in this context. Troubleshooting and bugfixing of the issue tracked out several bugs in router advertisement procedures, some of which are fixed in this commit. * zebra/interface.c * if_zebra_new_hook(): update to treat -1 as "uninitialized" * nd_dump_vty(): idem * zebra/rtadv.c * rtadv_send_packet(): update processing of "router lifetime" field, "home agent" option and "home agent lifetime" field to conform to RFC6275 better * ipv6_nd_ra_interval_msec(): update MaxRtrAdvInterval range check, make sure it never exceeds (initialized) AdvDefaultLifetime * ipv6_nd_ra_interval(): idem * ipv6_nd_ra_lifetime(): update AdvDefaultLifetime range check, make sure it never falls below MaxRtrAdvInterval * ipv6_nd_homeagent_lifetime(): update HomeAgentLifetime range check * no_ipv6_nd_ra_lifetime(): update to treat -1 as "uninitialized" * no_ipv6_nd_homeagent_lifetime(): idem * rtadv_config_write(): idem
