[AGENT++] Whether OID had been defined the depth by RFC?

[qinyd at tom.com]

Hi Frank and all list members:

SNMP++ :
#define MAX_OID_LEN      128 /* max subid's in an oid */

But some ExtensionDLL cannot support length 128.

In function ExtensionDLL::get_next_request,
the OID which be treated with the predecessor() was so long,that the MasterAgent would be coredump 
when called the function query(SNMP_PDU_GETNEXT, ...)

Any suggestions would be greatly appreciated.
