[Qemu-devel] [PATCH 14/15] monitor: Convert do_info_balloon() to QObject

[Luiz Capitulino <lcapitulino@redhat.com>]

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.
