This is vodz' latest patch. Sorry it took so long...

    1) ping cleanup (compile fix from this patch already applied).
    2) traceroute call not spare ntohl() now (and reduce size);
    3) Fix for functions not declared static in insmod, ash, vi and mount.
    4) a more simple API cmdedit :))
    5) adds "stopped jobs" warning to ash on Ctrl-D and fixes "ignoreeof" option
    6) reduce exporting library function index->strchr (traceroute), bzero->memset (syslogd)
