	* mi/mi-cmds.h (mi_no_values, mi_simple_values, mi_all_values): New
	declarations.
	* mi/mi-cmd-stack.c (mi_cmd_stack_list_locals): Use string
	constants instead of literals for MI command options.
	* mi/mi-cmd-var.c (mi_no_values, mi_simple_values, mi_all_values):
	New variables.
	(mi_parse_values_option, mi_print_value_p): New functions.
	(mi_cmd_var_list_children): Use mi_parse_values_option and
	mi_print_value_p.
	(mi_cmd_var_update): Support a PRINT_VALUES option.  Update calls
	to varobj_update_one.
	(varobj_update_one): Take a print_values argument.  Call
	mi_print_value_p.
	* varobj.c (varobj_get_gdb_type): New function.
	* varobj.h (varobj_get_gdb_type): New prototype.
