Check if subscribers exist.

The rest of the arguments to this function specify additional parameters for checking for subscriptions to subsets of an event type. The arguments must in sets of:
and must end with AST_EVENT_IE_END.
If the ie_type specified is not AST_EVENT_IE_END, then it must be followed by a valid IE payload type. If the payload type specified is AST_EVENT_IE_PLTYPE_EXISTS, then the 3rd argument should not be provided. Otherwise, a payload must also be specified.
Example usage:
This example will check if there are any subscribers to MWI events for the mailbox defined in the "mailbox" variable.

The rest of the arguments to this function specify information elements to match for retrieving events from the cache. They are specified in the form:
and must end with AST_EVENT_IE_END.
If the ie_type specified is not AST_EVENT_IE_END, then it must be followed by a valid IE payload type. If the payload type specified is AST_EVENT_IE_PLTYPE_EXISTS, then the 3rd argument should not be provided. Otherwise, a payload must also be specified.
Example Usage:
This example will check for an MWI event in the cache that matches the specified mailbox. This would be the way to find out the last known state of a mailbox without having to poll the mailbox directly.

The rest of the arguments to this function specify information elements to add to the event. They are specified in the form:
and must end with AST_EVENT_IE_END.
If the ie_type specified is not AST_EVENT_IE_END, then it must be followed by a valid IE payload type. The payload type, EXISTS, should not be used here because it makes no sense to do so. So, a payload must also be specified after the IE payload type.
Example usage:
This creates a MWI event with 3 information elements, a mailbox which is a string, and the number of new and old messages, specified as integers.

The purpose of caching events is so that the core can retain the last known information for events that represent some sort of state. That way, when code needs to find out the current state, it can query the cache.
The event API already knows which events can be cached and how to cache them.

Example usage:
This creates a subscription to AST_EVENT_MWI events that contain an information element, AST_EVENT_IE_MAILBOX, with the same string value contained in peer->mailbox. Also, the event callback will be passed a pointer to the peer.
