In addition to the automatic changes, also do the following,
needed due to recent Gnulib changes.
* admin/merge-gnulib (AVOIDED_MODULES): Add btoc32,
c32_apply_type_test, c32_get_type_test, c32isalnum, c32rtomb,
c32tolower, c32toupper, localeinfo, mbrtoc32-regular.
Remove btowc, iswctype, mbrtowc, wcrtomb, wctype, wctype-h.
Also remove iswblank, iswdigit, iswxdigit, locale-h, raise,
stdarg-h, some of which perhaps could have been removed earlier.
* configure.ac (_REGEX_AVOID_UCHAR_H): New macro.
* 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.
