Jonas Ådahl 8e99996321 Introduce experimental Wayland backend
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.
