[Qemu-commits] [COMMIT cc1d9c7] monitor: Convert do_info_balloon() to QObject

[Anthony Liguori]

From: Luiz Capitulino <address@hidden>

On success return a QInt with the balloon's value.

This also introduces monitor_print_balloon() to print the
balloon information in the user protocol.

Please, note that errors are not being converted yet.
