cat, head, ptx, shuf, tac, tail, tee, tr, and uniq used freopen on stdout, and were potentially vulnerable. dircolors, du, and tsort only used it on stdin, which is unaffected by freopen_safer, but this covers all uses for consistency. * cfg.mk (sc_require_stdio_safer): New rule. * gl/modules/xfreopen (Depends-on): Add freopen-safer. * gl/lib/xfreopen.c (includes): Use stdio--.h. * src/ptx.c (includes): Likewise. * src/shuf.c (includes): Likewise. * src/uniq.c (includes): Likewise. * src/dircolors.c (includes): Likewise. * src/du.c (includes): Likewise. * src/tsort.c (includes): Likewise.
