2020-03-15	Unify event loop functions as puglUpdate()	David Robillard
	The previous separation between polling and dispatching was a lie, especially on MacOS where it is impossible to only poll for events without dispatching anything. Providing such an API is misleading, and problematic in various other ways. So, merge them into a single puglUpdate() function which can do the right thing on all platforms. This also adds the behaviour of actually processing all events in the given time interval, which is almost always what clients actually want to do when using a positive timeout (naively doing this before caused terrible input lag).
2020-03-15	Add type and flags to world	David Robillard
	Unfortunately this is an API break, but there's no reasonable way to deprecate the old function and this is required for things to work correctly. The type will be used in following commits to tick the main loop and dispatch events correctly for either case.
