[snmp] Stack as Agent (was: deadlock when destroying a context)

Sounds like a good idea!
If you're willing to provide this piece of code, we'll certainly look at
it and add it to the stack if we're happy with it.

The problem is that the stack has no architecture that helps you to
gather the response data. (The main reason is that we don't want to build in MIB knowledge (or a MIB parser)).
Therefor it isn't easy to come up with a good (or extensive) example.

The best examples are in 
examplevX/ReceiveTrap.requestPduReceived()
(where X = (2c or 3))

This example 
- tests for an incoming GetRequest(sysContact0) 
- responds with my name and email address 

Let me know what example you'd like to have and I'll see what I can do.

Unfortunately I'm not up to speed with Sun's 1.5 JVM MIB (sorry). 
Allegedly the source code is available? So maybe we could wrap some code
around it. 
However, I'm not sure I've got time in the near future to have a look.
Don't let that prevent you to send us your thoughts. Feedback, ideas and
suggestions are always welcome!
