["Môshe Van der Sterre" <moshevds@xxxxxxxxx>]

Here is the dissector I mentioned before.

Most opcodes are not yet implemented, but the dissector is in a
usefull state already.
We need it for a tshark running 24/7:
tshark -i eth0 -R gdsdb.prepare.statement
So we will be able to monitor an external application using the database.

As far as I know this dissector conforms to the usual way things are
done with wireshark. But I like to hear about anything I missed, or
should have done another way.

This dissector currently has all the features the current
(packet-ib.c) dissector has, so replacing it right away should not be
a problem.

I hope to implement the other opcodes soon, most of the work is
already done. But I have still to look at ways to generate (correct)
packages for some (those not or ralely used by the current firebird
package). Extensive testing with invalid packages is also on the todo
list.
