458a3453da tests: qemuhotplug: Remove leftovers for non-event testing
DO_TEST_ATTACH and DO_TEST_ATTACH_EVENT now do the same thing so we can
remove the latter including the infrastructure.

eaaecd9f55 tests: qemuhotplug: Use DEVICE_DELETED event in all hotunplug tests
Currently all supported qemu versions now have support for the
DEVICE_DELETED event. This means that testing the old approach is a
waste of time.

Always add the QEMU_CAPS_DEVICE_DEL_EVENT capability in the hotplug test
and fix existing test cases.

The 'disk-virtio', 'disk-usb', 'disk-scsi', and 'disk-scsi-2' already
had variants that used the event, so the non-event variants will be
removed.

For all other cases the QMP_DEVICE_DELETED macro is used to add the
correct reply.

a1dce96236 qemu: Use the 'device_id' property of SCSI disks to avoid regressing
QEMU accidentally exposed the id of -drive (or same value as disk
serial, if provided) in one of the identifiers visible from the guest.

To avoid regression in case when -blockdev will be used we need to

85a8e364f3 qemu: caps: Introduce capability for 'device_id' property of 'scsi-disk'
The property allows to control the guest-visible content of the vendor
specific designator of the 'Device Identification' page of a SCSI
device's VPD (vital product data).

QEMU was leaking the id string of -drive as the value if the 'serial' of
the disk was not specified. Switching to -blockdev would impose an ABI
change.

1328a830ce qemu: command: Drop formatting of 'media=cdrom' from -drive
For SCSI, IDE, and AHCI cdroms the appropriate device types which select
the correct media are used. In qemu there's one other code path that
looks at -drive media=cdrom in the XEN pv code. Thankfully we don't
support it with qemu (see qemuBuildDiskDeviceStr). All other devices
ignore it as the comment states, thus we can drop that code.

The test fallout is expectedly only in the test added for uncommon cdrom
types.

e67b6dcf36 qemu: capabilities: Probe caps for 'ide-hd' instead of 'ide-drive'
Since commit a4cda054e7 we are using 'ide-hd' and 'ide-cd' instead of
'ide-drive'. We also should probe capabilities for 'ide-hd' instead of
'ide-drive'. It is safe to do as 'ide-drive' is the common denominator
of both 'ide-hd' and 'ide-cd' so all the properties were common.

For now the test data are modified by just changing the appropriate type
when probing for caps.

from the units used by QEMU for the corresponding parameters. For
example, libvirt defines migration bandwidth in MiB/s while QEMU expects
B/s. Let's add a unit field to qemuMigrationParamsTPMapItem for
automatic conversion when translating between libvirt's migration typed
parameters and QEMU's migration paramteres.

This patch is a preparation for future parameters as the existing
VIR_MIGRATE_PARAM_BANDWIDTH parameter is set using "migrate_set_speed"
