Continue implementation of class Fl_Window_Driver according to Albrecht's plan.

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!".
