    Fix some minor races in hosts lacking mkostemp. · e0fdb694
    Paul Eggert authored
    Gnulib's emulation of mkostemp doesn't have races that Emacs's does.
    * configure.ac (mkostemp): Remove check for this function;
    gnulib does the check now.
    (mkstemp): Remove check for this no-longer-used function.
    * lib/mkostemp.c, lib/secure_getenv.c, lib/tempname.c, lib/tempname.h:
    * m4/mkostemp.m4, m4/secure_getenv.m4, m4/tempname.m4:
    New files, copied from Gnulib.
    * lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate.
    * admin/merge-gnulib (GNULIB_MODULES): Add mkostemp.
    * lib-src/movemail.c (main):
    * lib-src/update-game-score.c (write_scores):
    Use mkostemp (which now works on all platforms, due to changes
    in the portability layer) rather than mktemp (which has a race)
    or mkstemp (which we no longer bother with).
    * src/callproc.c (create_temp_file):
    * src/filelock.c (create_lock_file):
    Assume mkostemp, since it's now provided by Gnulib.
