  wayland: Don't let multiple threads dispatch wayland events at once wl_display_dispatch() will block if there are no events available, and while we try to avoid this by using SDL_IOReady() to verify there are events before calling it, there is a race condition between SDL_IOReady() and wl_display_dispatch() if multiple threads are involved. This is made more likely by the fact that SDL_GL_SwapWindow() calls wl_display_dispatch() if vsync is enabled, in order to wait for frame events. Therefore any program which pumps events on a different thread from SDL_GL_SwapWindow() could end up blocking in one or other of them until another event arrives. This change fixes this by wrapping wl_display_dispatch() in a new mutex, which ensures only one thread can compete for wayland events at a time, and hence the SDL_IOReady() check should successfully prevent either from blocking.
