* locale/localeinfo.h: Rewritten for new locale system, using locale data files and with <langinfo.h> interface. * locale/setlocale.c: Rewritten to use locale data files. * langinfo.h: New file. * locale/langinfo.h: New file. * locale/nl_langinfo.c: New file. * locale/loadlocale.c: New file. * locale/lc-ctype.c: New file. * locale/lc-messages.c: New file. * locale/lc-monetary.c: New file. * locale/lc-numeric.c: New file. * locale/lc-time.c: New file. * locale/categories.def: New file. * locale/Makefile (headers): Remove localeinfo.h. (distribute): New variable; put localeinfo.h here, and categories.def. (routines): Add loadlocale. (categories): New variable. (aux): Use that to get C-category and lc-category. * ctype/ctype.h (_IS*): Use independent bits for all but _ISalnum. * locale/C-ctype.c, locale/C-messages.c: New files. * locale/C-monetary.c, locale/C-numeric.c, locale/C-time.c: Default "C" locale data updated for new locale system. * locale/C-collate.c: File removed. * locale/C-ctype_ct.c: File removed. * locale/C-ctype_mb.c: File removed. * locale/C-response.c: File removed. * locale/localeconv.c: Use _NL_CURRENT macro to access locale data. * stdio/printf_fp.c, stdio/vfprintf.c, stdio/vfscanf.c, stdlib/strtod.c, time/asctime.c, time/strftime.c: Include ../locale/localeinfo.h and use _NL_CURRENT macro to access locale data. * time/localtime.c: Don't include <localeinfo.h>. * time/tzset.c: Don't use locale items for default TZ value or "GMT" string (use "UTC"). * stdio/vfprintf.c [USE_IN_LIBIO] (PAD): Only call the function if WIDTH>0; update DONE. * malloc/malloc.c (morecore): Fix last change to calculate by blocks instead of bytes.
