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.

It seems this allows not to #include <windows.h> in the public header files.

Adding two new driver types for each platform. Fl_..._System_Drivers exist once per application and provide an interface for to file and filename handling, timers, locking, multithreading, etc. .
The Fl_..._Window_Driver class is instantiated once for every window in the system and corresponds closely to (and actually inherits from) Fl_X. The difference now is, that there is one Fl_X/Fl_Window_Driver base class, and one platform version that derives from it.
