[AGENT++] Response to wrong snmpEngineId

[Jochen Katz]

Hi Marcus,

if only the agent changes its id, the discovery mode on the agent does
not have to enabled, as the agent is authoritative. But if the agent
sends informs, you will need discovery.

Discovery is enabled by default...

The snmp++ code will give a report if discovery is disabled and a
timeout if enabled.

For the next release this will be changed to give reports in both cases.
Until then you can disable discovery in the agent and enable it only
during the time the agent sends pdus where it is not authoritative.
