[DGD] DGD 1.5.5

[bart at wotf.org]

With dgd supporting outbound tcp connections and this addition of udp,
'vanilla' dgd supports most things the network extensions seem to be used for.
I do use the ability to open arbitrary ports, and there are some slight
differences in behavior.

I suppose this also means being able to send udp datagrams from an udp user
object, but is it possible to initiate sending udp from dgd?

Often one can just have the client send an initial datagram, but for example
for sending things to the syslog service on *BSD (which doesn't support
rsyslog like syslog over tcp), dgd would serve as the client, and can't expect
the server to send an initial datagram.
