Subject: 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)
