Update.
* posix/tst-fnmatch.input: Add test case for FNM_PERIOD handling with
FNM_EXTMATCH.
* posix/fnmatch_loop.c: Optimize handling of ?() and @().
* posix/fnmatch.c: Define STRLEN and STRCAT appropriately.
* posix/Versions [libc] (GLIBC_2.2.3): Add fnmatch.
* posix/fnmatch.c: Define with new default version GLIBC_2.2.3 to
avoid running binaries with libc versions without FNM_EXTMATCH support.
* include/wchar.h: Add prototype for __wcscat.
* wcsmbs/wcscat.c: Define __wcscat and make wcscat weak alias.
