There is very little overlap in the machine types available
on different architectures, so broadly speaking checking the
machine type is usually enough; regardless, it's better to
check the architecture as well.

Make sure related functions, eg. all qemuDomainIs*(), are
close together instead of being sprinkled throughout both
the header and implementation file, and also that all
qemuDomainMachine*() functions are declared first since
we're going to make a bunch of them static later on.

QEMU plans to deprecate 'query-events' as it's non-extensible. Events
are also described by 'query-qmp-schema' so we can use that one instead.

This patch adds detection of events to
virQEMUCapsProbeQMPSchemaCapabilities using the same structure declaring
them for the old approach (virQEMUCapsEvents). This is possible as the
name is the same in the QMP schema and our detector supports that
trivially.

For any complex queries virQEMUCapsQMPSchemaQueries can be used in the
future.

For now we still call 'query-events' and discard the result so that it's
obvious that the tests pass. This will be cleaned up later.

Signed-off-by: NPeter Krempa <pkrempa@redhat.com>

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.

Avoid regressions by disallowing the BLOCKDEV capability.
Signed-off-by: NPeter Krempa <pkrempa@redhat.com>

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
always specify it ourselves.
Signed-off-by: NPeter Krempa <pkrempa@redhat.com>

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.

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.
