xorg server: major update 1.13.4 -> 1.14.3

- The 1.13 branch gets no updates since April,
  so I thought it's a good time to switch.
- Some xorg modules needed to be updated to build,
  but some don't have the update (probably all very obscure).
- Maybe it would be good to update the intel driver (or some others),
  I don't know.
