+ for term-driver configuration, ensure that the driver pointer is initialized in setupterm so that terminfo/termcap programs work. + amend fix for Debian #542031 to ensure that wattrset() returns only OK or ERR, rather than the attribute value (report by Miroslav Lichvar). + reorder WINDOWLIST to put WINDOW data after SCREEN pointer, making _nc_screen_of() compatible between normal/wide libraries again (patch by Miroslav Lichvar) + review/fix include-dependencies in modules files (report by Miroslav Lichvar).
