Windows' native headers using some our RT_* define's names for other things.
Since the naming isn't very nice anyways, introducing some new ones
(X11_RESTYPE_NONE, X11_RESTYPE_FONT, X11_RESTYPE_CURSOR) and define the old
ones as an alias to them, in case some out-of-tree code still uses them.

With thins change, we don't need to be so extremely careful about include
ordering and have explicit #undef's in order to prevent name clashes on
Win32 targets.
