For Wayland, this is mostly the input protocol having changed, although there's also the SHM pool API, the cursor API, as well as fullscreen and ping. Also port to the new (months-old) xkbcommon API, as used by Weston 0.95. This involves having xkbcommon manage the state for us, where appropriate. Fans of multi-layout keyboards (or just caps lock) will no doubt appreciate these changes. Signed-off-by: Daniel Stone <daniel@fooishbar.org>
