copywin() couldn't seem to decide whether it should work in window or screen coordinates - and managed to do neither. Change copywin() to use window relative coords (as ncurses and solaris do), and change overwrite() and overlay() to use the modified interface. It is now possible to use overwrite() to save part of curscr while a temporary window is drawn. Fixes PR/26506
