Summary: [python bindings] SNMPv3 segfault. Wrong initializer used!

Initial Comment:
The  "netsnmp_create_session_v3" function  (inside client_intf.c) doesn't intialize the *session pointer properly. This causes a segmentation fault on GET/WALK operations.

Tested with:

- NET-SNMP: 5.5 (tar.gz) , SVN version (revision 17933)
- OS version: Ubuntu /  Kernel  2.6.24-23-generic #1 SMP Wed Apr 1 21:47:28 UTC 2009 i686 GNU/Linux

Example:

import netsnmp

var =  netsnmp.Varbind('.1.3.6.1.2.1.1.1.0)
t   =  netsnmp.snmpget(var 
                       ,DestHost=HOST
                       ,Community=COMMUNITY
                       ,Version=3
                       ,UseNumeric=1
                       ,Timeout=int(0.5 * SNMP_ONE_SECOND)
                       ,Retries=RETRIES

                       ,SecLevel='authNoPriv'
                       ,SecName='foo'
                       ,AuthProto='MD5'
                         ,AuthPass='00112233445566778899aabbccddeeff '
                       )
