-	Consolidate XChar2b macros for the X, W32, and NS
-	Suggested by Jan Djärv in:
-	https://lists.gnu.org/archive/html/emacs-devel/2014-07/msg00203.html
-	* w32gui.h (STORE_XCHAR2B, XCHAR2B_BYTE1, XCHAR2B_BYTE2): Move the
-	fallback definitions to dispextern.h.
-	* nsgui.h (STORE_XCHAR2B, XCHAR2B_BYTE1, XCHAR2B_BYTE2): Likewise.
-	Share the same definition with W32.
-	* xterm.h (STORE_XCHAR2B, XCHAR2B_BYTE1, XCHAR2B_BYTE2): Move to ...
-	* dispextern.h (STORE_XCHAR2B, XCHAR2B_BYTE1, XCHAR2B_BYTE2):
-	... here for the consistency with W32 and NS.
