cleanups before extracting a set. Should'nt do anything for an install, as the filesystem shouldn't contain files that need to be removed. cleanup_dist() is called before extract_file() for each set (the set name is passed as parameter). It will open a file /dist/<set name>_obsolete if it exists. This file should contain a list of files (absolutes pathnames) that needs to be removed. cleanup_dist() will lstat() each file to determine if it's there and if it's a directory or not. It will then unlink() entries that are not directories and then rmdir() directories. If a directory is not empty (it should now if the list of files is correct) it will be renamed to <directory.old> and the user will be warned. Other changes: - move prototype of target_prefix() in defs.h, don't maintain a copy of it in each file. - in install.c, after MSG_disksetupdone, do a wclear(stdscr) (display was clobbered after it). - kill MSG_openmsgbuf, it's not used anywhere - after MSG_disksetupdone in upgrade, don't call MENU_ok, do it the same way as in install. - add wclear(stdscr);/wrefresh(stdscr); before calling MENU_distset (another display problem ...) - While I'm there, move ask_verbose_dist() before MENU_distmedium. This way, if all go well the user can go away one ftp starts and come back once sets are extracted.
