JSON args for -netdev were added as precursor for adding the 'dgram'
network backend type. Enable the detection and update test cases using
DO_TEST_CAPS_LATEST.
Enabling the capability also ensures that the -netdev argument is
validated against the QAPI schema of 'netdev_add' which was already
implemented but not enabled.
The parser supporting JSON was added by qemu commit f3eedcddba3 and
enabled when adding stream/dgram netdevs in commit 5166fe0ae46.

The qemuxml2argvtest pseries-feature parse failure tests uses a symlink
to the pseries-features.xml test domain and control which feature it is
supposed to fail by excluding it from the capabilities list. The
advantage of this approach is that the same XML can be used in multiple
tests.
One downside is that any new pseries capability must be declared in all
existent tests, otherwise all other tests can break if this new
capability happens to be validated early in qemu_validate.c. Any new
parse_error test must declare all other existent capabilities.
Another downside is the fact that we're testing fairly improbable
scenarios: all pseries capabilities being tested here were introduced by
the same QEMU version, 4.2.0, at least as far as libvirt is aware of.
This means that it's no possible to have a scenario where, for example,
ccf-assist is not present but cfpc is. And last, but not the least, it's
getting in the way of our effort to convert all pseries tests to not use
explicit capabilities.
Changing all these tests to use DO_TEST_PARSE_ERROR_NOCAPS() will allow
us to test exactly what we want to test, which is the parse error given
for each feature if the binary does not have support for it. The XML
being used for each test can be simplified to just declare a single
feature. In the end we'll end up with more XML lines, but less
complexity inside qemuxml2argvtest.c.

Eliminate most of the pseries tests that are using explicit qemu caps

The changes made are trivial: rename the .args/.err files to
ppc64-latest.(args/err) and do the required changes to match the newest
capabilities.
A notable expection were tests pseries-console-native,
pseries-serial-compat and pseries-serial+console-native. These are
aliases of the pseries-serial-native tests. In this case we needed to

QEMU offers two attributes for handling reset requests of an USB
host device: guest-reset and guest-resets-all. When combined they
act as follows:
1) guest-reset=false
The guest is not allowed to reset the physical USB device.
2) guest-reset=true,guest-resets-all=false
The guest is allowed to reset the device when it is not yet
initialized (aka no USB bus address assigned). Usually this results
in one guest reset being allowed. This is the default behavior.
3) guest-reset=true,guest-resets-all=true
The guest is allowed to reset the device as it pleases.
Now, there's a clear 1:1 mapping with our representation of
guestReset, so generating cmd line is trivial.

Some USB devices have a buggy firmware that either crashes on

Fortunately, QEMU offers a way to skip device reset either
completely, or if device is not initialized yet. Expose this

Currently, a firmware configuration such as
<os firmware='efi'>
<firmware>
<feature enabled='yes' name='enrolled-keys'/>
</firmware>
</os>
will correctly pick a firmware that implements the Secure Boot
feature and initialize the NVRAM file so that it contains the
keys necessary to enforce the signing requirements. However, the
lack of a
<loader secure='yes'/>
element makes it possible for pflash writes to happen outside
of SMM mode. This means that the authenticated UEFI variables
where the keys are stored could potentially be overwritten by
malicious code running in the guest, thus making it possible to
circumvent Secure Boot.
To prevent that from happening, automatically turn on the
loader.secure feature whenever a firmware that implements Secure
Boot is chosen by the firmware autoselection logic. This is
identical to the way we already automatically enable SMM in such
a scenario.
Note that, while this is technically a guest-visible change, it
will not affect migration of existings VMs and will not prevent
legitimate guest code from running.

Generally speaking, when firmware autoselection is in use we

two exceptions:
* we still want the path to the NVRAM file to be customizable;
* using <loader secure='yes'/> was how you would ask for a
firmware that implements the Secure Boot feature in the
original approach to firmware autoselection, so we want to
keep that working.
Anything else should result in a descriptive error.

For finding the best matching CPU model for a given set of features
while we don't know the CPU signature (i.e., when computing a baseline
CPU model) we've been using a "shortest list of features" heuristics.
This works well if new CPU models are supersets of older models, but
that's not always the case. As a result it may actually select a new CPU
model as a baseline while removing some features from it to make it
compatible with older models. This is in general worse than using an old
CPU model with a bunch of added features as a guest OS or apps may crash
when using features that were disabled.
On the other hand we don't want to end up with a very old model which
would guarantee no disabled features as it could stop a guest OS or apps
from using some features provided by the CPU because they would not
expect them on such an old CPU.
This patch changes the heuristics to something in between. Enabled and
disabled features are counted separately so that a CPU model requiring
some features to be disabled looks worse than a model with fewer
disabled features even if its complete list of features is longer. The
penalty given for each additional disabled feature gets bigger to make
longer list of disabled features look even worse.

Upcoming patches will remove support for qemu-2.12. Since tests of
'sev' use hacked data we need to use our capability dump of qemu-6.0 as
it has the required fields.

Originally when I started working on '-blockdev' support I added version
locked variants of all the relevant disk tests locked to qemu-2.12, but
blockdev was finally enabled with qemu-4.2.
This patch bumps the rest of the test cases with no functional changes
related to disks.

The 'device_id' property was added in qemu-4.0. Since upcoming patch
will be modernizing all disk test cases we specifically want to preserve
the instance of 'device_id' not being used with qemu-3.1 and earlier.
Change the 'disk-cache' and 'disk-shared' cases to have a qemu-3.1 and a
qemu-4.1 version for testing pre-'device_id' and pre-blockdev scenarios.
