Reorganize classes Fl_System_Driver and Fl_Screen_Driver

These virtual members are moved from Fl_Screen_Driver to Fl_System_Driver
- wait(double)
- ready()

These virtual members are moved from Fl_System_Driver to Fl_Screen_Driver
- copy(const char *stuff, int len, int clipboard, const char *type)
- void paste(Fl_Widget &widget, int clipboard, const char *type)
- clipboard_contains(const char *type)
- clipboard_notify_change()

These members are moved from Fl_X11_Screen_Driver to Fl_X11_System_Driver
- poll_or_select_with_delay(double time_to_wait)
- poll_or_select()
and are made virtual in preparation for the introduction of class
Fl_Unix_System_Driver.
