Add a new PangoLanguage type to represent language tags; these can

Sat Jun  9 17:36:09 2001  Owen Taylor  <otaylor@redhat.com>

	* pango/pango-types.h pango/pango-utils.c: Add a new PangoLanguage
	type to represent language tags; these can efficiently be compared
	and don't need to be copied. Also add pango_language_matches()
	to match a language tag against a pattern.

	* pango/pango-item.[ch] pango/pango-layout.c: Move extra_attrs
	from PangoItem to PangoAnalysis. Add a language tag field to
	PangoAnalysis. (#55894)

	* pango/pango-attributes.[ch] (pango_attr_iterator_get_font): Return
	the language tag as well.

	* pango/pango-attributes.[ch]: Rename PangoAttrLang to PangoAttrLanguage,
	and make it hold a PangoLanguage.

	* pango/pango-context.[ch]: Rename pango_context_{get,set}_lang() to
	pango_context_{get,set}_language().

	* **.[ch]: Adapt to PangoLanguage and s/lang/language/ changes.

	* modules/basic/basic-x.c modules/basic/tables-big.i: Add support
	for ordering character sets differently for different language
	tags.

	* pango/itemize.c: Remove old, unused file.

	* pango/pango-context.c (pango_itemize): Reduce number of mallocs
	by allocating one array of PangoAnalysis instead of many arrays.
