[SNMP4J] SNMPv1 skip counter64 data

[Vivi Zhang]

Frank:

According to RFC 2089:
o On an SNMPv1 GETNEXT request, we skip the object instance and
         fetch the next object instance that follows the one with a
         syntax of Counter64.

According to snmp4j CHANGES.txt
SNMP v1.8:

* Added: Counter64 skipping for SNMPv1 GETNEXT request
  processing.

I would expect the fix is in SNMP4J 1.9.3C, but seems it is not.

The version I ma using : SNMP4J is version 1.9.3c, and SNMP4JAgent is 
version 1.2.1d.

To verify the issue:
The command I used :
java -cp SNMP4J.jar org.snmp4j.tools.console.SnmpRequest -c v1public -v 
1 -t 3000 -Otd 192.168.41.21 1.3.6.1.2.1.31

Tracing by WireShark, seems SNMP4j does not skip count64 mib data.
