	PR c++/19076
	PR c++/6628
	* cp-tree.h (cp_apply_type_quals_to_decl): Declared.
	* decl.c (grokdeclarator): Pedwarn about qualifying a function
	type.
	Add qualifiers when declaring a typedef of a function type.
	Member function pointers pick up the qualifiers of the typedef
	used to declare them.
        Don't complain about creating cv-qualified function types.
	Complain about qualified function typedefs that are used to
	declare non-static member functions or free functions.
	Use cp_apply_type_quals_to_decl.
	(start_preparsed_function): Use cp_apply_type_quals_to_decl.
	(grokclassfn): Use cp_apply_type_quals_to_decl.
	* error.c (dump_type_suffix): Print qualifiers for function
	types.
	* pt.c (tsubst_decl): Use cp_apply_type_quals_to_decl.
	(tsubst): When substituting a function type into a member
	pointer type, pass along the qualifiers.
	(unify): Unify member pointers to member function pointers.
	* tree.c (cp_build_qualified_type_real): Function types may be
	qualified. This includes restrict qualifiers.
	* typeck.c (cp_apply_type_quals_to_decl): New function to replace
	use of c_apply_type_quals_to_decl. Drops qualifiers that are being
	added to function types.
