bgpd: fix bgp_node locking issues
* bgpd: Connected table locks were being locked but not unlocked, such that eventually a lock would exceed 2^31 and become negative, thus triggering an assert later on. * bgp_main.c: (bgp_exit) delete connected elements along with ifp's. * bgp_nexthop.c: (bgp_nexthop_lookup{,_ipv6}) add missing unlocks (bgp_multiaccess_check_v4) ditto (bgp_connected_{add,delete}) Use a distinct memtype for bgp_connected_ref. (bgp_scan_finish) reset the nexthop cache to clean it up when bgpd exits * bgp_route.c: fix missing bgp_node unlocks * lib/memtype.c: (memory_list_bgp) add MTYPE_BGP_CONN * testing: has been tested for almost 2 months now.
