One more platform-dependent type is necessary: struct dirent
Create a new header file, FL/platform_types.h, to define all
types whose definition is platform-dependent.
This file is for C because it is included by scandir_XXX.c

There was one obvious warning in src/fl_read_image.cxx, but others
have to do with incomplete code and platform specific definitions.
I'm not entirely happy with these changes. Temporary changes have been
marked with 'FIXME' and should be removed later if possible.

struct stat is considered a platform-specific type.
The Unix, Mac OS, and WIN32 platforms define it with #include <sys/stat.h>
Other platforms may do that their own way.

Files fl_read_image_mac.cxx and fl_read_image_win32.cxx are no longer used;
their content is now in Fl_XXX_Screen_Driver.cxx

This file contained nearly only platform-specific code.

for coherence with the Fl::screen_driver() function.

All functions of fl_utf.c keep their C API in fl_utf8.cxx

File fl_utf8.h defines the xchar type with a platform-dependent value (wchar_t or unsigned short).
But it is used exclusively by WIN32 code (0 use in cross-platform code, 0 use in APPLE
or in USE_X11 code).
Thus, we can just get rid of this type and replace it by wchar_t where it is used.

File src/Fl_win32.cxx is now compiled instead of included in Fl.cxx.

These methods are intended to be used instead of pWindow->method()
for better code readability and easier porting of methods from
Fl_Window to Fl_Window_Driver.
New methods: x(), y(), y(), h(), shown(), parent(), border(),
visible(), and visible_r().
We should add more such methods if appropriate.

This removes a bunch of
friend class Fl_XXX_Window_Driver;
declarations from Fl_Window.H, and therefore allows
to add a new window driver without modifying the platform-independent code.
The Fl_PicoXXX_Window_Driver classes have been modified but not tested ==> test needed.
File Fl_X11_Window_Driver.cxx contained this:
// DO NOT call this if the window is not mapped!
static int can_xdbe()
{ ... }
The new code does call can_xdbe() before any window is mapped,
and does work. Since can_xdbe() asks the X server whether it supports
the Xdbe extension, I don't see why this should not work without a
mapped window. This point should be clarified by the author of
"DO NOT call this if the window is not mapped!".

Still unclear whether the implementation of the flush() functions follows the plan.
The Fl_Printer class is fully rewritten under the driver model.
