http://jira.cubrid.org/browse/APIS-977

Purpose

• to eliminate user confusion, 2-way expression is unified with the oracle_compat_number_behavior system parameter.
• in order for the broker to deliver the value of the system parameters including oracle_compat_number_behavior to the client, the broker extends the broker info that the client receives using the RESERVED field.
• Change the CAS Protocol version from PROTOCOL_V11 to PROTOCOL_V12 to express the extension of the above protocol
