Preparing for X.org 7.4

Most of X.org 7.4 has already been released. We need to check on compatibility of xorg-server with MidnightBSD. There are many changes in the hardware detection logic in X.org 7.4.

An upgrade plan for mports must be determined and feasibility to include it in the next major MidnightBSD release. Some components might be upgradable now.

X.org 7.4 update

The basic components have already been placed in mports. There are still some compatibility issues with the mouse + keyboard (without editing some config files) and the video acceleration code src/sys/dev/drm needs to be updated to handle newer hardware.
