* coreutils.h: remove prototype of non-existing xgetoptfile_sort_uniq
and add boilerplate.
* networking/{ipaddr,ip,iplink,iproute,iptunnel}.c: touch includes
and use short boilerplate.
* libiproute/iproute.c: rename round to avoid clashes with older
SuSE gcc and use short boilerplate.
Another issue I found was with the iproute utility. While using another
program I found that it failed because the "ip route del" command was
not found. I looked at the full iproute implementation and this command
exists. The busybox version has the "ip route delete" command. I have
created a patch which makes the "ip route del" command an alias to the
"ip route delete" command.
- ip route flush
- different usage for telnetd in inetd mode
- changes for the default flags of the ip features
- if no /usr requested, udhcpc should use the script also without /usr.
