[Qemu-devel] [PATCH 00/30] complete conversion to hotplug-handler API

[Igor Mammedov <imammedo@redhat.com>]

Series unifies different hotplug mechanisms to a recent
hotplug-handler API and does shallow conversion of
devices that still use legacy qdev hotplug to it dropping
not used after that legacy hotplug path [29/30].
It also relaces SCSI's own way to do hotplug/unplug with
hotplug-handler callbacks leaving it the only method
perform hotplug tasks.
And the last patch [30/30] allows to unplug of BUS-less
devices using hotplug-handler API.

Converted devices are covered with new hotplug
unit-tests, except of:
 s390x-*: I have no idea how or means to test it, but code
          is close to virtio, so it's converted using
          virtio template
 pvscsi: is broken, so no means to test it
