[Qemu-devel] [PATCHv5 0/3] DEVICE_DELETED event |

libvirt has a long-standing bug: when removing the device,
it can request removal but does not know when the
removal completes. Add an event so we can fix this in a robust way.
First patch only adds the event for devices with ID, second path adds it
for all devices and adds a path fields. Split this way for ease of
backport (stable downstreams without QOM would want to only take the
first patch), and also because the 2nd/3rd patches might turn out to be
more controversial - if they really turn
out such I'd like just the 1st one to get applied while we discuss 2 and
3.

Changes from v4:
- Add extra triggers and extra fields as requested by Markus
Changes from v3:
- Document that we only emit events for devices with
and ID, as suggested by Markus
Changes from v2:
- move event toward the end of device_unparent,
so that parents are reported after their children,
as suggested by Paolo
Changes from v1:
- move to device_unparent
- address comments by Andreas and Eric
