Event Loop 2.0 API and Windows implementation (#638) * Rename EventsLoop and associated types to EventLoop * Rename WindowEvent::Refresh to WindowEvent::Redraw * Remove second thread from win32 backend * Update run_forever to hijack thread * Replace windows Mutex with parking_lot Mutex * Implement new ControlFlow and associated events * Add StartCause::Init support, timer example * Add ability to send custom user events * Fully invert windows control flow so win32 calls into winit's callback * Add request_redraw * Rename platform to platform_impl * Rename os to platform, add Ext trait postfixes * Add platform::desktop module with EventLoopExt::run_return * Re-organize into module structure * Improve documentation * Small changes to examples * Improve docs for run and run_return * Change instances of "events_loop" to "event_loop" * Rename MonitorId to MonitorHandle * Add CHANGELOG entry * Improve WaitUntil timer precision * When SendEvent is called during event closure, buffer events * Fix resize lag when waiting in some situations * Update send test and errors that broke some examples/APIs * Improve clarity/fix typos in docs * Fix unreachable panic after setting ControlFlow to Poll during some RedrawRequested events. * Fix crash when running in release mode * Remove crossbeam dependency and make drop events work again * Remove serde implementations from ControlFlow * Fix 1.24.1 build * Fix freeze when setting decorations * Replace &EventLoop in callback with &EventLoopWindowTarget * Document and implement Debug for EventLoopWindowTarget * Fix some deadlocks that could occur when changing window state * Fix thread executor not executing closure when called from non-loop thread * Fix buffered events not getting dispatched * Fix crash with runner refcell not getting dropped * Address review feedback * Fix CHANGELOG typo * Catch panics in user callback
