        * filter.c: (access_list_remark_cmd) buffer_putstr doesnt need cast
          to u_char. (ipv6_access_list_remark_cmd) ditto.
          if.c: ditto
        * network.c: (readn/writen) pointer arg should be type u_char.
        * plist.c: needs to include stream.h, not declare stream functions
          internally.
          (various) Add static qualifier to internal functions.
          (prefix_list_type_str) extraneous breaks in switch statement.
          (ip_prefix_list_description_cmd) buffer_putstr doesnt need cast
        * stream.h: depends on plist.h and export stream_put_prefix
        * vty.c: (vty_<telnet option build functions>) should use
          unsigned char, telnet options are 0 -> 255.
        * zclient.c: various u_char<->char type cleanups.
        * zebra.h: Having to define CMSG_* can apply to more than just
          BSDI_NRL.
        * ripd.c: (rip_distribute_update_all) distribute list hook
          function pointer prototype requires struct prefix_list * arg.
          (rip_distribute_update_all_wrapper) update to pass required arg,
          NULL.
