* intl/tst-gettext3.c: New file.

	* intl/tst-gettext3.sh: New file.
	* intl/Makefile (distribute): Add tst-gettext3.sh.
	(test-srcs): Add tst-gettext3.
	(tests): Depend on tst-gettext3.out.
	(tst-gettext3.out): New rule.
	(CFLAGS-tst-gettext3.c): New variable.

	Fix bug exposed by tst-gettext3.
	* intl/gettextP.h (struct converted_domain): New type.
	(struct loaded_domain): Remove the conv, conv_tab fields. Add
	conversions, nconversions fields.
	(_nl_init_domain_conv): Remove declaration.
	(_nl_free_domain_conv): Remove declaration.
	(_nl_find_msg): Add convert argument.
	* intl/dcigettext.c (DCIGETTEXT): Call _nl_find_msg with convert=1.
	(_nl_find_msg): Add convert argument. When a conversion to a different
	charset is needed, create a new converted_domain element, instead of
	throwing away the old converted translations.
	(get_output_charset): New function.
	* intl/loadmsgcat.c (_nl_init_domain_conv): Remove function.
	(_nl_free_domain_conv): Remove function.
	(_nl_load_domain): Initialize the conversions array to empty. Use
	_nl_find_msg instead of _nl_init_domain_conv to retrieve the header
	entry.
	(_nl_unload_domain): Free the conversions array and its contents.

	* intl/gettextP.h (struct loaded_domain): Remove codeset_cntr field.
	(struct binding): Likewise.
	* intl/bindtextdom.c (set_binding_values): Drop codeset_cntr
	modifications.
