Ensure that received packets are at least as long as the rwho packet

header before trying to process them. Without this sanity check,
rwhod can attempt to byte-swap all of memory when a short packet
is received, and so dies with a SIGBUS.

While I'm here, change two other syslog messages to be more
informative: use dotted quad rather than hex notation for IP
addresses, and include the source IP in the 'bad from port' message.
