Subject: [PATCH] wayland: Add support for the Wayland winsys

* Adds EGL_WL_bind_wayland_display extension
* Adds wayland-egl library
* Adds wl_dispmanx_buffer protocol extension

TODO: Check that platform_get_dimensions() returning swapchain_count == 1 is correct

TODO: Remove the requirement of passing a valid DispmanX element handle to
the SwapBuffers and CreateSurface RPC calls. This will remove the need to open
a DispmanX display from the clients.

TODO: wl_dispmanx_server_buffer should probably be defined in a
private header that can be included from EGL and vc_* instead of in
vc_vchi_dispmanx.h

 Whilst 64-bit userspace is not officially supported, some of the libraries will work for it. To cross compile, install gcc-aarch64-linux-gnu and g++-aarch64-linux-gnu first. For both native and cross compiles, add the option ```--aarch64``` to the buildme command.
 
 Note that this repository does not contain the source for the edidparser and vcdbg binaries due to licensing restrictions.
+
+To build support for the Wayland winsys in EGL, execute the buildme script like this:
+
+$ BUILD_WAYLAND=1 ./buildme.
