	Enable symbolic colors and color expressions in style
	properties. Fixes bug #346751.

	* gtk/gtkrc.c (rc_parse_token_or_compound): add GtkRcStyle
	parameter and replace symbolic colors by color constants.

	(gtk_rc_parse_assignment): likewise. Also support parsing of
	expressions of the form identifier(compound).

	(gtk_rc_parse_style): pass the GtkRcStyle to
	gtk_rc_parse_assignment().

	(gtk_rc_parse_statement): pass NULL since we don't have a
	GtkRcStyle here.
