	* glib/gregex.c:
	* glib/gregex.h: New functions: g_regex_ref(), g_regex_unref() which
	replaces g_regex_free(); g_match_info_get_regex(), g_match_info_get_string();
	g_regex_check_replacement().
	Made g_match_info_expand_references() accept NULL; changed GRegexEvalCallback
	to take only arguments which are likely to be actualy used.

	* docs/reference/glib/glib-sections.txt:
	* glib/glib.symbols: Added new functions.

	* tests/regex-test.c: Test them.
