truckman 4d196a467d Use strlcpy() instead of strncpy() when copying ifname to ensure
that it is NUL terminated.  Additional NUL padding is not required
for short names.

Use sizeof(destination) in a few places instead of IFNAMSIZ.

Cast afp->af_ridreq and afp->af_addreq  to make the intent of
the code more obvious.
