Applet proposal - gratuitous ARP daemon

I've written a small gratuitous ARP daemon that could be modified to become
a busybox applet and contributed if there's any interest.

It periodically scans the list of network interfaces and sends out
gratuitous ARP packets on each interface that has
a non-zero MAC address, non-zero IP address and is in the running state. The
frequency defaults to once per minute, but is configurable via a command
line option.

It is useful for wireless clients that don't necessarily generate much
traffic themselves and need to announce their presence to
forgetful Access Points, etc.
