Attached is a modified arping.c

Changes..

Replace xerror() with error_msg();exit(); it was marginally cheaper when
error_msg was already being used.

Moved global variables that are only used in one function into that
function.

Removed some headers that didnt need to be #include'd, also used some c
headers instead of linux/ headers.

Removed the set_signal function as its only called twice, didnt appear
to be wirth a function declaration.

I think send_pack could be incorporated into catcher, and recv_pack into
arping_main, that should allow some more globals to be moved.

Maybe there is some common code between arping and other network applets
that can be shared.
