[AGENT++] GetBulk

how yould you calculate it? I think its not possible, because nobody
knows how long the oids and values of all possible agents are.

Both values are configured in config_snmp_pp.h. Increasing
MAX_SNMP_PACKET will increase stack usage (as some functions use local
arrays of that size (will be changed for next releases)) and increasing
PDU_MAX_VBS will increase the size of Pdu class (as it holds a
preallocated array of Vb objects).

After you have increased these defines, make tests to ensure that all
agents and managers you use can accept that large SNMP messages.
