The flag was based on a version check which no longer made sense. Remove
the flag by replacing it's only use by an arch-check which is equivalent
at this point.

2a273072b6 qemucapabilitiestest: Hack/fix version in qemu-3.1 tests
The test dumps for x86_64 and ppc64 were generated from pre-release
qemu-3.0-rc1/rc2 and thus wouldn't pass our minimum version check.

As these are very old, fix the version info we use for our check to 3.1
without re-generating them and keep the version tag intact.

49a85978b7 qemu: capabilities: Retire QEMU_CAPS_QXL_MAX_OUTPUTS and QEMU_CAPS_VIRTIO_GPU_MAX_OUTPUTS
Both are supported by qemu-2.11 and later, so we don't have to check for
them explicitly.

Note that QXL is supported only on x86_64, thus on other arches only the
capability for 'virtio-gpu' is removed.

97475487f8 Revert "qemu: capablities: detect acpi-pci-hotplug-with-bridge-support"
This reverts commit 58ba0f6a3d.

Conflict:
  * src/qemu/qemu_capabilities.[ch]

    Because other new cap flags had been added since the original
    commit, reformatting was necessary to follow the "groups of
    five" pattern.

  * tests.qemucapabilitiesdata/caps_6.2.0.x86_64.xml

    This file was added after the original commit that we
    are reverting, so had to be manually edited to remove
    the two capabilities.

d65eb5dd8d Revert "qemu: capabilities: Remove QEMU_CAPS_PIIX4_ACPI_HOTPLUG_BRIDGE"
This reverts commit 618e8665db.

This is the first in a series of 10 commits that revert (in reverse
order) the changes to add the <acpi-hotplug-bridge state='on|off'/>
switch to libvirt domain XML, which unfortunately needs to be removed
due to QEMU developers discovering a flaw with the design of the QEMU
commandline switch used to implement the libvirt switch that will
likely result in a new and different method of selecting hotplug
modes. Because the libvirt switch has not been in any official
releases of libvirt, we are still able to remove it completely, rather
than deprecating it.

The original commits began with commit
58ba0f6a3d. The other original commit
IDs are documented in each revert commit.

618e8665db qemu: capabilities: Remove QEMU_CAPS_PIIX4_ACPI_HOTPLUG_BRIDGE
Commit 58ba0f6a3d added a capability which
is supported by all qemu versions we support. Remove it and the
associated dead code. Since the capability isn't present in any upstream
release we can delete it completely.

Specifically the commit itself states that it was introduced "around
(qemu) 2.1". The rest of the code handles properly that the feature is
used only on x86 with the i440fx machine so the capability is pointless.

58ba0f6a3d qemu: capablities: detect acpi-pci-hotplug-with-bridge-support
qemu added support for i440fx specific global boolean flag

PIIX4_PM.acpi-pci-hotplug-with-bridge-support

around version 2.1. This flag is enabled by default. When disabled, it
turns off acpi pci hotplug for cold plugged pci bridges in i440fx
machine types.

Very recently, in qemu version 6.1, the same global option was also
added for q35 machine types as well.

ICH9-LPC.acpi-pci-hotplug-with-bridge-support

This option turns on or off acpi based hotplug for cold plugged pcie
bridges like pcie root ports. This flag is also enabled by
default. Please refer to the following qemu changes:

c0e427d6eb5fef ("hw/acpi/ich9: Enable ACPI PCI hot-plug")
17858a16950860 ("hw/acpi/ich9: Set ACPI PCI hot-plug as default on Q35")

This patch adds the corresponding qemu capabilities in libvirt. For
i440fx, the capability is detected as
QEMU_CAPS_PIIX_ACPI_HOTPLUG_BRIDGE. For q35, the capability is
detected as QEMU_CAPS_ICH9_ACPI_HOTPLUG_BRIDGE.

Please note that the test specific qemu capabilities .replies files
has already been updated as a part of regular refreshing them when a
new qemu version is released. Hence, no updates to those files are
required.

qemu introduced these options in 2eb1cd0768 ("s390x: CPACF: Handle key

The problem is that they are exposed even for architectures which don't
actually in fact support those.

Make the two capabilities a bit more useful by assuming them only on
s390 and thus removing them from other arches.
