Update from Gnulib by running admin/merge-gnulib

Browse source 
* admin/merge-gnulib (GNULIB_MODULES): Add stringeq.
With current Gnulib it is already present as in indirect dependency;
listing it here because Emacs now depends on it directly.
* lib-src/ebrowse.c, lib-src/etags.c:
(streq): Remove, as Gnulib defines this now.
* lib/fseterr.c, lib/fseterr.h, lib/issymlink.c, lib/issymlink.h:
* lib/issymlinkat.c, lib/stdio-consolesafe.c, lib/string.c:
* m4/fseterr.m4, m4/gettext_h.m4, m4/stringeq.m4:
New files from Gnulib.
* src/conf_post.h (tzfree) [__ANDROID_API__ >= 35]: Remove.
