events: Rework event subsystem (add_event, send_event) to be more versatile.
add_event_ex is added that takes an extra user_data pointer. This pointer is passed to the callback (add_event and add_event_ex have slightly different callbacks types). All callbacks also get the event id passed. Events added with add_event_ex must be removed with remove_event_ex because the user_data pointer must match in addition to the callback pointer. On the other add_event is simplified to omit the oneshort parameter which was almost always false (still there with add_event_ex). As a side effect the ata_idle_notify callbacks are changed as well, they do not take a data parameter anymore which was always NULL anyway. This commit also adds some documentation to events.h Change-Id: I13e29a0f88ef908f175b376d83550f9e0231f772
