Gave rarpd back the ability to poke temporary entries into the arp
table; arptab.c is really a hacked up version of arp.c that only
supports adding temporary entries. (This stuff is nasty -- I wish I
knew what was so wrong with SIOCSARP/SIOCGARP/etc... that made the
BSD developers decide to take it out.) The idea here is that the
client issuing the rarp is expected to be in the middle of booting
and would therefore be unable to answer arp queries from other machines
on the wire. Having rarpd stuff a temporary entry for the booting
host into the local arp table helps keep arp requests from going unanswered.
Also added ether_print() and ether_ntoa() to the ether_addr.c module.
Eventually I'll get ether_aton() and ether_hostton() written and
then this file can be dropped straight into libc. (Assuming no one
objects, of course. :)
