x11: give error messages if Xorg only supports DRI2 and mesa only DRI3

Browse source 
By default mesa now only supports DRI3.

If Xorg is not activating DRI3, it will show an almost empty screen, which is not working.
No error message is given.
This e.g. happens at  Debian package
xserver-xorg-video-intel at the i915 gallium driver.

This commit generates error messages to explain the problem.
