When processing remote NDIS control message packets, the USB Net
device emulator checks to see if the USB configuration descriptor
object is of RNDIS type(2). But it does not check if it is null,
which leads to a null dereference error. Add check to avoid it.

IDE is only implemented by very few architectures (mostly PC). The
test doesn't actually need a block device attached to the
BlockBackend, so just drop it and adjust the reference output
accordingly.

The relative ordering of "device_del" return value and the
"DEVICE_DELETED" QMP event depends on the architecture being
tested. On x86 unplugging virtio disks is asynchronous
(=qdev_unplug()= → =hotplug_handler_unplug_request()=) while on s390x
it is synchronous (=qdev_unplug()= → =hotplug_handler_unplug()=). This
leads to the actual output on s390x consistently differing from the
reference output (that was probably produced on x86).
The easiest way to address this is to filter out QMP events in
067. The DEVICE_DELETED event is already getting explicitly tested by
the Python-based test case 139, so the test coverage should be
unaffected. Make use of the recently introduced _filter_qmp_events()
to remove QMP events from the test case output and adjust the
reference output accordingly.
The tr / sed / tr trick used for filtering was suggested by Max Reitz
<mreitz@redhat.com>.

There's no need to keep throttle_conflicting(), throttle_is_valid()

When testing the ranges of valid values, set_cfg_value() creates
sometimes invalid throttling configurations by setting bucket.max
while leaving bucket.avg uninitialized.
While this doesn't break the current tests, it will as soon as
we unify all functions that check the validity of the throttling
configuration.
This patch ensures that the value of bucket.avg is valid when setting
bucket.max.

a way to set any options except the format eg

The BDRV_O_INACTIVE flag should only be set for images explicitly opened
by the user. snapshot=on needs to create a new qcow2 image and write
some metadata to it. This is not a problem because it can't come from
the source, so there's no reason to mark it as BDRV_O_INACTIVE, even
though it is opened while waiting for the migration to complete.
This fixes an assertion failure when -incoming and snapshot=on are
combined.

The new feature for qcow2: storing bitmaps.
This patch adds new header extension to qcow2 - Bitmaps Extension. It
provides an ability to store virtual disk related bitmaps in a qcow2
image. For now there is only one type of such bitmaps: Dirty Tracking
Bitmap, which just tracks virtual disk changes from some moment.
Note: Only bitmaps, relative to the virtual disk, stored in qcow2 file,
should be stored in this qcow2 file. The size of each bitmap
(considering its granularity) is equal to virtual disk size.

This patch allows the instantiation of the vfio-amd-xgbe device
from the QEMU command line (-device vfio-amd-xgbe,host="<device>").
The guest is exposed with a device tree node that combines the description
of both XGBE and PHY (representation supported from 4.2 onwards kernel):
Documentation/devicetree/bindings/net/amd-xgbe.txt.
There are 5 register regions, 6 interrupts including 4 optional
edge-sensitive per-channel interrupts.
Some property values are inherited from host device tree. Host device tree
must feature a combined XGBE/PHY representation (>= 4.2 host kernel).
2 clock nodes (dma and ptp) also are created. It is checked those clocks
are fixed on host side.
AMD XGBE node creation function has a dependency on vfio Linux header and
more generally node creation function for VFIO platform devices only make
sense with CONFIG_LINUX so let's protect this code with #ifdef CONFIG_LINUX.

Some passthrough'ed devices depend on clock nodes. Those need to be
generated in the guest device tree. This patch introduces some helpers
to build a clock node from information retrieved in the host device tree.
- copy_properties_from_host copies properties from a host device tree
node to a guest device tree node
- fdt_build_clock_node builds a guest clock node and checks the host
fellow clock is a fixed one.
fdt_build_clock_node will become static as soon as it gets used. A
dummy pre-declaration is needed for compilation of this patch.

Current qemu_fdt_getprop exits if the property is not found. It is
sometimes needed to read an optional property, in which case we do
not wish to exit but simply returns a null value.
This patch converts qemu_fdt_getprop to accept an Error **, and existing
users are converted to pass &error_fatal. This preserves the existing
behaviour. Then to use the API with your optional semantic a null
parameter can be conveyed.
