Subject: 2004-02-17 Paul Jakma <paul@dishone.st>

        * bgpd.h: (bgp_peer) add fd_local and fd_accept
          file descriptor's, fd becomes a pointer to one of these.
        * bgpd.c: (global) adjust for fact that fd is now a pointer.
          (peer_create_accept) removed.
        * bgp_route.c: (global) adjust for change of peer fd to pointer
        * bgp_packet.c: (bgp_collision_detect) adjust and remove the
          "replace with other peer" hack.
        * bgp_network.c: (bgp_accept) Remove the dummy peer hack.
          Update peer->fd_accept instead.
          (global) Adjust fd references - now a pointer.
        * bgp_fsm.c: (global) adjust peer fd to pointer.
          (bgp_connection_stop) new function, to stop connection.
          (global) adjust everything which closed peer fd to use
          bgp_connection_stop().
