printf() & friends return the number of characters written on success, negative value on error. monitor_printf(), monitor_vfprintf(), monitor_vprintf(), error_printf(), error_printf_unless_qmp(), error_vprintf(), and error_vprintf_unless_qmp() return void. Some of them carry a TODO comment asking for int instead. Improve them to return int like printf() does. This makes our use of monitor_printf() as fprintf_function slightly less dirty: the function cast no longer adds a return value that isn't there. It still changes a parameter's pointer type. That will be addressed in a future commit. monitor_vfprintf() always returns zero. Improve it to return the proper value.
