[Qemu-devel] [PATCH 05/11] QMP: advertise asynchronous messages

[Luiz Capitulino <lcapitulino@redhat.com>]

With feature negotiation support asynchronous messages are
going to behave like any protocol capability, that is, it
is disabled by default, it can be negotiated and has to be
advertised.

TODO: update spec.
