Merge from Gnulib; use ‘open’ for O_CLOEXEC
This incorporates: 2017-08-15 renameat: ensure declaration in <stdio.h> on NetBSD 2017-08-15 extensions: enable NetBSD specific extensions 2017-08-14 open: support O_CLOEXEC 2017-08-13 reallocarray: new module * admin/merge-gnulib (AVOIDED_MODULES): Remove ‘open’, since it now supports O_CLOEXEC and this simplifies Emacs. * build-aux/config.guess, lib/fcntl.in.h, lib/stdio.in.h: * lib/stdlib.in.h, m4/extensions.m4, m4/stdlib_h.m4: Copy from Gnulib. * lib/cloexec.c, lib/cloexec.h, lib/open.c: * m4/mode_t.m4, m4/open-cloexec.m4, m4/open.m4: New files, copied from Gnulib. * lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate. * lib-src/etags.c (O_CLOEXEC) [WINDOWSNT]: Remove, as Gnulib does this for us. * src/filelock.c (create_lock_file): * src/sysdep.c (emacs_open, emacs_pipe): Don’t worry about O_CLOEXEC == 0, as Gnulib no longer sets it to 0.
