[Qemu-devel] [PATCH 8/9] hmp: Add hmp_announce_self

["Dr. David Alan Gilbert (git)" <dgilbert@redhat.com>]

From: "Dr. David Alan Gilbert" <dgilbert@redhat.com>

Add an HMP command to trigger self annocements.
Unlike the QMP command (which takes a set of parameters), the HMP
command reuses the set of parameters used for migration.
