Commit f1d5516ab583 introduces a test in some iotests to check if
the machine is a s390-ccw-virtio and to select virtio-*-ccw rather
than virtio-*-pci.
We don't need that because QEMU already provides aliases to use the correct
virtio interface according to the machine type.
This patch removes all virtio-*-pci and virtio-*-ccw to use virtio-*
instead and remove get_virtio_scsi_device().
This also enables virtio-mmio devices (virtio-*-device)

There are many existing qcow2 images that specify a backing file but
no format. This has been the source of CVEs in the past, but has
become more prominent of a problem now that libvirt has switched to
-blockdev. With older -drive, at least the probing was always done by
qemu (so the only risk of a changed format between successive boots of
a guest was if qemu was upgraded and probed differently). But with
newer -blockdev, libvirt must specify a format; if libvirt guesses raw
where the image was formatted, this results in data corruption visible
to the guest; conversely, if libvirt guesses qcow2 where qemu was
using raw, this can result in potential security holes, so modern
libvirt instead refuses to use images without explicit backing format.
The change in libvirt to reject images without explicit backing format
has pointed out that a number of tools have been far too reliant on
probing in the past. It's time to set a better example in our own
iotests of properly setting this parameter.
iotest calls to create, rebase, and convert are all impacted to some
degree. It's a bit annoying that we are inconsistent on command line
- while all of those accept -o backing_file=...,backing_fmt=..., the
shortcuts are different: create and rebase have -b and -F, while
convert has -B but no -F. (amend has no shortcuts, but the previous
patch just deprecated the use of amend to change backing chains).

Most of our Python unittest-style tests only support the file protocol.
You can run them with any other protocol, but the test will simply
ignore your choice and use file anyway.
We should let them signal that they require the file protocol so they
are skipped when you want to test some other protocol.

In Python 3, several functions now return iterators instead of lists.
This includes range(), items(), map(), and filter(). This means that if
we really want a list, we have to wrap those instances with list(). But
then again, the two instances where this is the case for map() and
filter(), there are shorter expressions which work without either
function.
On the other hand, sometimes we do just want an iterator, in which case
we have sometimes used xrange() and iteritems() which no longer exist in
Python 3. Just change these calls to be range() and items(), works in
both Python 2 and 3, and is really what we want in 3 (which is what
matters). But because it is so simple to do (and to find and remove
once we completely switch to Python 3), make range() be an alias for
xrange() in the two affected tests (044 and 163).
In one instance, we only wanted the first instance of the result of a
filter() call. Instead of using next(filter()) which would work only in
Python 3, or list(filter())[0] which would work everywhere but is a bit
weird, this instance is changed to use a generator expression with a
next() wrapped around, which works both in 2.7 and 3.

Now that iotest 093 test proves that the throttling configuration
survives a blockdev-remove-medium/blockdev-insert-medium pair, the
original reason for declaring these commands experimental is gone
(see commit 6e0abc251dd4f8eba1f53656dfede12e5840e83b).

The default cpu model on s390x does not provide zPCI, which is
not yet wired up on tcg. Moreover, virtio-ccw is the standard
on s390x, so use the -ccw instead of the -pci versions of virtio
devices on s390x.

BlockdevRef is an alternate of BlockdevOptions (inline definition) and
str (reference to an existing block device by name). BlockdevRef
value "" is special: "no block device should be referenced." It's
actually interpreted that way in just one place: optional member
@backing of COW formats. Semantics:
* Present means "use this block device" as backing storage
* Absent means "default to the one stored in the image"
* Except "" means "don't use backing storage at all"
The first two are perfectly normal: when the parameter is absent, it
defaults to an implied value, but the value's meaning is the same.
The third one overloads the parameter with a second meaning. The
overloading is *implicit*, i.e. it's not visible in the types. Works
here, because "" is not a value block device ID.
Pressing argument values the schema accepts, but are semantically
invalid, into service to mean "do something else entirely" is not
general, as suitable invalid values need not exist. I also find it
ugly.
To clean this up, we could add a separate flag argument to suppress
@backing, or add a distinct value to @backing. This commit implements
the latter: add JSON null to the values of @backing, deprecate "".
Because we're so close to the 2.10 freeze, implement it in the
stupidest way possible: have qmp_blockdev_add() rewrite null to ""
before anything else can see the null. Works, because BlockdevRef
occurs only within arguments of blockdev-add. The proper way to do it
would be rewriting "" to null, preferably in a cleaner way, but that
requires fixing up code to work with null. Add a TODO comment for
that.

Or, rather, force the open of a backing image if one was specified
for creation. Using a similar -unsafe option as rebase, allow qemu-img
to ignore the backing file validation if possible.
It may not always be possible, as in the existing case when a filesize
for the new image was not specified.
This is accomplished by shifting around the conditionals in
bdrv_img_create, such that a backing file is always opened unless we
provide BDRV_O_NO_BACKING. qemu-img is adjusted to pass this new flag
when -u is provided to create.
Sorry for the heinous looking diffstat, but it's mostly whitespace.

The supported blockdev-add is not compatible to its experimental
predecessors; bump all Since: tags to 2.9.

x-blockdev-change need a bit more work, so leave them alone for now.

Now that QAPI supports boxed types, we can have unions at the top level
of a command, so let's put our real options directly there for
blockdev-add instead of having a single "options" dict that contains the
real arguments.
blockdev-add is still experimental and we already made substantial
changes to the API recently, so we're free to make changes like this
one, too.

We want to remove the 'id' option for blockdev-add. This removes one
user of the option and makes it use only node names.
Some test cases that used to work with an unattached BlockBackend are
removed, either because they don't make sense with an attached device or
because the equivalent test case with an attached device already exists.

While in the long term we want throttling to be its own block filter
BDS, in the short term we want it to be part of the BB instead of a BDS;
even in the long term we may want legacy throttling to be automatically
tied to the BB.
blockdev-insert-medium and blockdev-remove-medium do not retain
throttling information in the BB (deliberately so). Therefore, using
them means tying this information to a BDS, which would break the model
described above. (The same applies to other flags such as
detect_zeroes.) We probably want to move this information to the BB or
its own filter BDS before blockdev-{insert,remove}-medium can be
considered completely stable.
Therefore, mark these functions experimental for the time being.
