charset="utf-8" To control that creating new machine type doesn't affect the previous types (their compat_props) and to check complex compat_props inheritance we need qmp command to print machine type compatibility properties. This patch adds the ability to get list of all the compat_props of the corresponding supported machines for their comparison via new optional argument of "query-machines" command. Since information on compatibility properties can increase the command output by a factor of 40, add an argument to enable it, default off.
