[PATCH 23/25] xf86Priv.h: Add some noreturn attributes suggested by gcc

[Alan Coopersmith]

Both functions call exit() at the end and have no other return path.
Also correct comment/heading to reflect commit 6450f6ca7ee0 moving
DoShowOptions into xf86Configure.c.

This overlaps with, but does not logically conflict with, Daniel's
[PATCH 21/31] XFree86: _X_UNEXPORT, so whoever lands second will have to merge.
