	[BZ #5443]
	* intl/dcigettext.c (__dcigettext): Get reader lock for locale data
	before looking for translation.
	* locale/duplocale.c: Transform __libc_setlocale_lock into rwlock.
	* locale/freelocale.c: Likewise.
	* locale/newlocale.c: Likewise.
	* locale/setlocale.c: Likewise.
	Based partially on a patch by ryo@np.css.fujitsu.com.
