monitor: Drop broken, unused asynchronous command interface
with bisection. Unfortunately, the bisection was extremely painful, because between a

Which tells me that it's not individual capabilities that are
broken by qemu 65207c59, but the entire libvirt capability retrieval. Apparently libvirt
is one user of that async monitor interface. (The message on commit 65207c59 itself
mentions "qmp_capabilities".)
Libvirt doesn't use async capabilities, so much as Markus accidentally
broke the QMP protocol by completely ditching support for the "id"
member that libvirt uses on every synchronous QMP command. Several
threads already exist on the matter:
