OCI8 2.0: Added a new oci_set_db_operation() user space function for the "DB Operation" tracing feature of Oracle DB 12c.

Currently this code is #ifdef'd out, since I can't consider the feature stable until an Oracle-side fix for Oracle bug 16695981 is available.  Having the code available in PHP OCI8 facilitates testing of any fix.
