Enabling event handler passthrough mode for a thread

To enable event handler passthrough mode for a thread, set the SRV_T_FULLPASSTHRU thread property to CS_TRUE in the Open Server connection handler.

Once event handler passthrough mode is enabled, Open Server invokes the full-passthrough handler each time a network read from the connection completes.

No events of type SRV_LANGUAGE, SRV_RPC, SRV_BULK, SRV_CURSOR, SRV_MSG, SRV_OPTION, or SRV_DYNAMIC are raised for the thread.

SRV_ATTENTION events, however, are raised. The Open Server application must install a SRV_ATTENTION handler to correctly handle cancel requests.
