fgets() will read at most size-1 bytes into the buffer and add a
terminating null-char at the end. Therefore it is not necessary to pass
a reduced buffer size when calling it.
This change was generated using the following semantic patch:
@@
identifier buf, fp;
@@
- fgets(buf, sizeof(buf) - 1, fp)
+ fgets(buf, sizeof(buf), fp)

Use warn_unused_result to enforce checking return value of rtnl_send,
and fix where the errors are.

A new option -p is added to the arpd command that accepts
a time indicating the number of seconds
to wait between kernel arp table polling attempts.
The minimum value is .1 (100ms).
If not specified, polling defaults to 30 seconds.

A bunch of misc utils basically reimplement the daemon() function (the
whole fork/close/chdir/etc...). Rather than do that, use daemon() as
that will work under nommu Linux systems that lack fork().
