[tcpdump-workers] tftp printing & RFC 1782 options

[Rob Braun]

The current tftp printing in tcpdump is rather minimalistic.
It prints out whether the packet is a read or write request,
and what the file being operated on is.  It currently does not
print out the mode or any of the tftp options.

Attached is a basic patch that will print out a few more fields
from the read and write request packets.
