C sucks: define XEventClass in terms of unsigned int, not CARD32.

Apparently pulling in Xmd.h here breaks qt, since they both define an
INT32 type (and incompatible ones even, since Xmd's is unsigned long on
ILP32 because whoever wrote Xmd.h is a C novice).

(Based on inputproto commit b5cbe2d93f.
