* locale/lc-time.c (_nl_init_era_entries, _nl_get_era_entry,

Browse Source 
_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.
