This patch introduces a new backend that enables GLFW applications to run on Wayland. For now, only output is supported (windowed and fullscreen). Pointer cursor management, input devices, clipboard etc are not supported yet. There are some concepts that can not be supported, more specifically glfwSetWindowPos, glfwGetWindowPos and glfwSetCursorPos, as they are not supported by Wayland. This patch also changes the time and joystick implementations used by the X11 backend to be shared between the Wayland backend and the X11 backend.
