* locale/lc-time.c (_nl_init_era_entries, _nl_get_era_entry,
_nl_select_era_entry): Moved to ... * time/era.c: ... here, new file. (_nl_init_era_entries, _nl_get_era_entry, _nl_select_era_entry): Add internal_function to definitions. Take an additional argument giving the `struct locale_data *' to use. * locale/lc-time.c (_get_alt_digit, _nl_get_walt_digit, _nl_parse_alt_digit): Moved to ... * time/alt_digit.c: ... here, new file. * time/lc-time-cleanup.c: New file. * locale/lc-time.c (_nl_postload_time, free_mem): Functions removed. * locale/localeinfo.h (_nl_postload_time): Remove decl. (_nl_cleanup_time): Declare it. (_nl_get_era_entry, _nl_select_era_entry): Update decls. (_get_alt_digit, _nl_get_walt_digit, _nl_parse_alt_digit): Likewise. * time/Makefile (aux): New variable: era, alt_digit, lc-time-cleanup. * time/strftime.c: Pass locale data to helper functions. * time/strptime.c: Likewise. * locale/localeinfo.h (struct locale_data): New member `private' * locale/loadlocale.c (_nl_intern_locale_data): Initialize it. (_nl_unload_locale): Call LOCALE->private.cleanup if it is set. * locale/C-collate.c: Update initializer. * locale/C-identification.c: Likewise. * locale/C-measurement.c: Likewise. * locale/C-telephone.c: Likewise. * locale/C-address.c: Likewise. * locale/C-name.c: Likewise. * locale/C-paper.c: Likewise. * locale/C-time.c: Likewise. * locale/C-numeric.c: Likewise. * locale/C-monetary.c: Likewise. * locale/C-messages.c : Likewise. * locale/C-ctype.c: Likewise. * time/strptime.c [USE_IN_EXTENDED_LOCALE_MODEL] (_NL_CURRENT_WORD): Redefine this too.
