[libvirt] [PATCH 17/23] Add a qemuMonitorGetObjectTypes() method for QMP qom-list-types command
From: "Daniel P. Berrange" <berrange(a)redhat.com>
Add a new qemuMonitorGetObjectTypes() method to support invocation
of the 'qom-list' JSON monitor command. No HMP equivalent
is required, since this will only be present for QEMU >= 1.2
Signed-off-by: Daniel P. Berrange <berrange(a)redhat.com>
