 We don't define HAVE_STDINT_H anywhere and it should be more safe using
 the system's definition of UINT32_MAX.

 This requires adaptations of arguments' types for the external
 references to MakeAtom() and CopyISOLatin1Lowered().

 These adaptations have been required in Xserver/include/dix.h,
 Xserver/include/dixfonts.c Xserver/dix/atom.c, Xserver/dix/dixutils.c,
 Xserver/os/oscolor.c.

hw/nxagent/NXdixfonts.c: Don't include <X11/fonts/fontstruct.h>. No symbol needed from that header file.

This makes the region code changes source compatible with existing
code, although none of them are used within the server source itself.

In NX, this patch is not really necessary, but it has been backported
with the previous patches for the sake of backporting the complete
mi/miregion.c -> dix/region.c change in X.Org.

v1: Keith Packard <keithp@keithp.com>
v2: Mike Gabriel <mike.gabriel@das-netzwerkteam.de> (backported to nx-libs)

This prepares the file to be moved from mi to dix. This patch
was done mechanically with the included scripts 'fix-miregion' run over
the entire X server and 'fix-miregion-private' run over
include/regionstr.h and mi/miregion.c.
