* 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.
