These are allegedly necessary to keep the output consistent,
but now that we're using a privileged config for the driver we
get the desired behavior out of the box, and as a bonus the
paths match what you would actually see on a regular host.

The qemuBuildMachineCommandLine() function is needlessly long.
Separate out parts that generate memory related arguments into
qemuAppendDomainMemoryMachineParams(). Unfortunately, expected
outputs for some qemuxml2argvdata cases needed to be updated
because the order in which arguments are generated is changed.
But there's no functional change.

By using the auto-generated NVRAM path in test data files, we won't see
bugs where a user specified path gets accidentally overwritten by a
post-parse callback, or VM startup. For example, this caused us to miss

qemu: Don't regenerate NVRAM path if parsed from domain XML

When -device is configured via JSON a bug [1] is triggered in qemu were
the DEVICE_DELETED event for the removal of the device frontend is no
longer delivered to libvirt. Without the DEVICE_DELETED event we don't
remove the corresponding entries in the VM XML.
Until qemu will be fixed we must stop using the JSON syntax for -device.
This patch removes the detection of the capability. The capability is
used only during startup of a fresh VM so we don't need to consider any
compaitibility steps for existing VMs.
For users who wish to use 'libvirt-7.9' and 'libvirt-7.10' with
'qemu-6.2' there are two possible workarounds:
- filter out the 'device.json' qemu capability '/etc/libvirt/qemu.conf':
capability_filters = [ "device.json" ]
- filter out the 'device.json' qemu capability via qemu namespace XML:
<domain type='kvm' xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'>
[...]
<qemu:capabilities>
<qemu:del capability='device.json'/>
</qemu:capabilities>
</domain>
We must never again use the same capability name as we are now
instructing users to filter it as a workaround so once qemu is fixed
we'll need to pick a new capability value for it.

We currently use -machine accel=XXX which is just a syntax sugar
for -accel XXX. The former doesn't allow specifying arguments for
accelerator, because all arguments passed to -machine are
treated as arguments of machine itself.
The -accel argument was introduced in QEMU commit
v2.9.0-rc0~70^2~19 and since our minimum required version is
newer (2.11.0) we can safely assume its existence and use it
without any capability.

Internally format the PCI controller properties into JSON, but convert
it back to a string so that we for now change just the SCSI controller.
The change in tests is expected as the 'port' field for various PCI
controllers is expected to be a number and thus can't be represented as
a hexadecimal value in JSON.
QEMU expects the following types:
'pci-bridge'
chassis_nr=<uint8> - (default: 0)
'pxb-pcie':
bus_nr=<uint8> - (default: 0)
'pcie-root-port'
port=<uint8> - (default: 0)
chassis=<uint8> - (default: 0)
hotplug=<bool> - (default: true)

virCommandToString has the possibility to return an already wrapped
string with better format than what we get from the test wrapper script.
The main advantage is that arguments for an option are always on the
same line which makes it more easy to see what changed in a diff and
prevents re-wrapping of the line if a wrapping point moves over the
threshold.
Additionally the used output is the same we have in the VM log file when
a VM is starting.

The preferred syntax for boolean options is to set the value "on" or
"off". QEMU 7.1.0 will deprecate the short format we currently use.
The long format has been supported with -chardev since at least 1.5.3,

The previous approac of just purging the alias combined with the fact
that we filled in fake machine types in the test data meant that if a
test case used an alias machine type such as 'pc' or 'q35' it would not
properly resolve to the actual data returned by qemu.
This started to be a problem since the CPU driver now looks at the
default CPU reported with the machine type.
This patch replaces the original approach of just removing the alias by
replacing it with a copy of the machine type data which the type would
alias to. This means that we are using the real data while we don't
modify the test output after every qemu upgrade.
Additionally this change will allow us to drop adding the fake machine
types later.
The test fallout is from actually excercising the CPU driver with
actual data.

Now that all pieces are in place (hopefully) let's enable -blockdev.
We base the capability on presence of the fix for 'auto-read-only' on
files so that blockdev works properly, mandate that qemu supports
explicit SCSI id strings to avoid ABI regression and that the fix for
'savevm' is present so that internal snapshots work.

Use the latest virt-manager to regenerate the files.
The command line is once again along the lines of
$ virt-install \
--name guest --os-variant fedora29 \
--vcpus 4 --memory 4096 --disk size=5 \
--graphics (none|vnc) \
--print-xml
with some minor tweaks performed afterwards.
This removes a number of inconsistencies between the files,
and makes it so the only differences are actually relevant
either to the architecture and machine type at hand, or to
having graphics rather than being headless.
