[Qemu-devel] [PATCH 24/25] Monitor: Introduce do_info_balloon()

[Luiz Capitulino]

Today, the do_info() function takes care of handling asynchronous
calls. But what we really want is to move all the asynchronous
stuff behind the (future) QMP API.

The QMP API will be directly used by handlers, and won't be tied to
the human monitor common code (like do_info()) in any way.

This commit takes the first step towards this goal: it introduces
do_info_ballon(), which is a regular info handler, except that it
knows how to directly call an asynchronous QMP handler.
