XNextEvent will block for input while holding the global Xlib mutex. This will cause a deadlock in even the most trivial multi-threaded application because OpenGL functions will need to hold the Xlib mutex too. Add EventsLoop::poll_one_event and EventsLoop::wait_for_input to provide thread-safe functions to poll and wait events from the X11 event queue using unix select(2) and XCheckIfEvent. This is a somewhat ugly workaround to an ugly problem. Fixes rust-windowing#779
