* debug.h (struct debug_write_fns): Remove ellipsis_type. Add int

	* debug.h (struct debug_write_fns): Remove ellipsis_type.  Add int
	and boolean parameters to function_type.  Add boolean parameter to
	method_type.
	(debug_make_ellipsis_type): Don't declare.
	(debug_make_function_type): Add debug_type * and boolean
	parameters.  Change all callers.
	(debug_make_method_type): Add boolean parameter.  Change all
	callers.
	(debug_get_parameter_types): Add boolean * parameter.  Change all
	callers.
	(debug_get_target_type): Declare.
	* debug.c (struct debug_function_type): Add fields arg_types and
	varargs.
	(struct debug_method_type): Add field varargs.
	(debug_ellipsis_type, ELLIPSIS_P): Remove.
	(debug_make_ellipsis_type): Remove.
	(debug_make_function_type): Add arg_types and varargs parameters.
	(debug_make_method_type): Add varargs parameter.
	(debug_get_parameter_types): Add pvarargs parameter.
	(debug_get_target_type): New function.
	(debug_write_type): In case DEBUG_KIND_FUNCTION, push argument
	types and pass count to function_type.  In DEBUG_KIND_METHOD, use
	a signed int for the count, don't call ellipsis_type, and pass
	varargs to method_type.
	* stabs.c (struct stab_demangle_info): Add varargs field.
	(stab_demangle_argtypes): Add pvarargs parameter.  Change all
	callers.
	(stab_demangle_args): Likewise.
	(stab_demangle_type): In case 'F', pick up argument types.
	* prdbg.c (pr_ellipsis_type): Remove.
	(pr_function_type): Add argcount and varargs parameters.
	(pr_method_type): Add varargs parameter.
	* ieee.c (ieee_ellipsis_type): Remove.
	(ieee_function_type): Add argcount and varargs parameters.
	(ieee_method_type): Add varargs parameter.  Remove most of
	function body, and just call ieee_function_type.
