	* sv/format_status_error_info: Add support for the format_status callback to gen_event Extend format_status for gen_server/gen_fsm termination error logging OTP-8630 sv/format_status_error_info When a gen_server, gen_fsm process, or gen_event terminates abnormally, sometimes the text representation of the process state can occupy many lines of the error log, depending on the definition of the state term. A mechanism to trim out parts of the state from the log has been added (using a format_status/2 callback). See the documentation.
2010-05-12	Add support for the format_status callback to gen_event	Steve Vinoski
	The gen_server and gen_fsm behaviors support the format_status callback to allow developers to specialize how callback module state appears within the return value of sys:get_status and within logged output resulting from abnormal process termination. This patch adds similar support to gen_event. Event handlers that export a format_status/2 function, which is an optional callback, and are registered with an event manager will now have their format_status callbacks invoked when sys:get_status is called on the event manager. The term returned from format_status for this case replaces the default handler state in the sys:get_status return value. This patch also extends gen_event to call an event handler's format_status function (if it exports one) should the handler terminate abnormally. The term returned from format_status is logged in place of the handler's state. This is intended to allow developers to control how much output is logged in the case of abnormal termination. The documentation is appropriately extended and new unit tests are added to cover the new gen_event format_status functionality.
