	* (general) fix some small compile errors, and mark several
          functions as static.
        * kernel_socket.c: (ifan_read) should be static.
          fix missing brackets.
          (ifm_read,ifam_read,rtm_read_mesg,kernel_read) Make static
          (ifam_read_mesg) make static. fix incorrect variable name.
          (rtm_read) make static. Fix call to rib_delete_ipv4 which
          should be rib_delete_ipv6.
          (routing_socket,kernel_init) should be static. Void argument
          should be specified as such, not left incomplete.
        * rt_netlink.c: rt.h should be included, contains prototypes of
          exported functions.
          (kernel_delete_ipv6_old) fix sign of index argument.
        * rt_socket.c: Exact same as previous. Also, make various
          functions static.
        * rtread_getmsg.c: Include zserv.h, which prototypes
          route_read. Make static.
        * rtread_sysctl.c: zserv.h and rt.h should be included.
          fix definition of route_read.
