Fix [9e31fd944934e269121fa78ff56b7b86f33e6db6|9e31fd9449]: X11/X.h and Windows.h have conflicting symbols.
*** POTENTIAL INCOMPATIBILITY *** on Windows only: gcc/clang/MSVC will generate new warnings in extensions when the "None" symbol is used incorrectly. Those warnings are all fixed in the core, that's what most of this commit is doing.
