qdev: 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.

qmp: fix handling of boolean values in qmp-shell

qmp-shell converts only integer arguments and the rest
is assumed to be strings which are faithfully sent as
quoted strings by json. But QEMU refuses to accept qmp
command with boolean argument whose value is escaped
as string.

Fix it by special-casing true/false keywords and store
value as corresponding boolean.

virtio-scsi: don't use pointer for configuration.

The configuration field must not be a pointer as it will be used for virtio-scsi
properties. So *conf is replaced by conf.

Instead of ignoring any errors that occur when adding properties
