Rather than creating stubs for every command that just return QERR_UNSUPPORTED, use 'if' conditions in the QAPI schema to fully exclude generation of the stats and fsinfo commands on platforms that can't support them. The command will be rejected at QMP dispatch time instead, avoiding reimplementing rejection by blocking the stub commands. This changes the error message for affected commands from {"class": "CommandNotFound", "desc": "Command FOO has been disabled"} to {"class": "CommandNotFound", "desc": "The command FOO has not been foun= d"} This has the additional benefit that the QGA protocol reference now documents what conditions enable use of the command.
