*	Darwin platform build fix (#10376)	David CARLIER	2020-09-09
\| \| \| \|	the event header seemingly being generic with libevent thus renaming it. openal and opengl are deprecated on newer mac os releases thus suppressing the build warnings.
*	Client eventmanager refactor (#7179)	Loïc Blot	2018-03-30
	* Drop EventManager from GameDef & do some client cleanups * EventManager is only used by Client. Don't expose it on Server & GameDef for nothing * Drop Client::event() in favor of direct calls to getEventManager * Cleanup some event put from new + put to put(new) * MtEvent: add Type(u8) enum * This will enhance event performance & ensure stricter type * Drop MtEvent::checkIs (unused) * clang-tidy reported fixes * Code style * Move event_manager.h to the client directory as it's only used by client Add EventManager unittests + switch to unordered_map as order is not important here Drop a unused function
