This adds the basic config bits needed for OpenBSD.

Patch from Pascal Stumpf <Pascal.Stumpf@cubes.de>

Most is just copied from the existing imake installation in
/usr/X11R6.  Additionally:

* Allow overriding CDESharedRev, X11ProjectRoot and ProjectRoot
* Add a new define to be able to override MINCLUDESRC too

(this allows me to build CDE without symlinking any include directories)
