[BZ #19633]
	Use specified locale for number formatting in strfmon_l.
	* locale/localeinfo.h (__nl_lookup, _nl_lookup_wstr)
	(__nl_lookup_word): New inline functions.
	* include/printf.h (__print_fp_l): Declare.
	* stdio-common/printf_fp.c (___printf_fp_l): Renamed from
	___printf_fp.  Add locale argument.  Replace _NL_CURRENT with
	_nl_lookup and _NL_CURRENT_WORD with _nl_lookup_word.
	(___printf_fp): New function.
	* stdlib/strfmon_l.c (__printf_fp): Remove declaration.
	(__vstrfmon_l): Call __printf_fp_l instead of printf_fp.
	* stdlib/tst-strfmon_l.c (do_test): New test.
	* stdlib/Makefile (tests): Add kt.
	(LOCALES): Build additional locales.
	(tst-strfmon_l.out): Require locales.
