/*
 * The following event types are "SIT events". When a client
 * makes a SIT event listening request, the Event Mediator
 * uses the SIT to fulfill the request. 
 *
 * When the SIT completes the task that is needed to fulfill
 * a certain SIT event listening request, the SIT reports an
 * event to the Event Mediator. The event report contains
 * event data that the Event Mediator passes further to the
 * listeners of the SIT event.
 *
 * EGetProtocolVersionEvent
 *     Event specification: VPN policy ID
 *     Event data:          Status of the task
 *                          Protocol type enumeration
 *
 * EStartVpnConnEvent
 *     Event specification: VPN IAP ID
 *                          VPN network ID
 *                          Real IAP ID
 *                          Real network ID
 *                          VPN policy ID
 *                          VPN NIF name
 *     Event data:          Status of the task
 *                          IKE policy handle
 *                          IPSec policy handle
 *                          VPN internal address information
 *
 * ECloseVpnConnEvent
 *     Event specification: IKE policy handle
 *                          IPSec policy handle
 *     Event data:          Status of the task
 *
 * EStartRealIapConnEvent
 *     Event specification: Real IAP ID
 *                          Real network ID
 *     Event data:          Status of the task
 *
 * EObserveRealIapConnEvent
 *     Event specification: Real IAP ID
 *                          Real network ID
 *     Event data:          Status of the task
 *                          Real IAP connection event
 *
 * The following event types are SIT related event types that are
 * used by the SIT for fetching task related information from the
 * Event Mediator. These event types are meant only for internal
 * use between the SIT and the Event Mediator.
 *
 * ETaskArrivedEvent
 *     Event specification: -
 *     Event data:          Event type of the task request
 *                          that requires fulfilling
 *                          Event specification ID of the task
 *                          request that requires fulfilling
 *
 * EFetchTaskInfoEvent
 *     Event specification: Event type of the task request
 *                          that requires fulfilling
 *                          Event specification ID of the task
 *                          request that requires fulfilling
 *     Event data:          One of the event specifications
 *                          listed below (depends on the event
 *                          type)
