	PR fortran/82173
	PR fortran/82168
	* decl.c (variable_decl): Check pdt template components for
	appearance of KIND/LEN components in the type parameter name
	list, that components corresponding to type parameters have
	either KIND or LEN attributes and that KIND or LEN components
	are scalar. Copy the initializer to the parameter value.
	(gfc_get_pdt_instance): Add a label 'error_return' and follow
	it with repeated code, while replacing this code with a jump.
	Check if a parameter appears as a component in the template.
	Make sure that the parameter expressions are integer. Validate
	KIND expressions.
	(gfc_match_decl_type_spec): Search for pdt_types in the parent
	namespace since they are instantiated in the template ns.
	* expr.c (gfc_extract_int): Use a KIND parameter if it
	appears as a component expression.
	(gfc_check_init_expr): Allow expressions with the pdt_kind
	attribute.
	*primary.c (gfc_match_actual_arglist): Make sure that the first
	keyword argument is recognised when 'pdt' is set.
