Port to new Wayland and xkbcommon APIs

Browse Source 
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.
