This reverts commit 618e8665db2e4c1a8e9a227045b99b48f6110c06.
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
58ba0f6a3d7342fba29edbbf2bb9cb5497c870e5. The other original commit
IDs are documented in each revert commit.

target-i386: Register aliases for feature names with underscores
Libvirt names use underscores so we conditionally tranlate the
names when talking to new QEMU. Since the min QEMU was raised to
version 2.11.0, all QEMU versions we talk to expect hypens, so
the translation can be done unconditionally.

Starting with QEMU-6.2 started accepting a JSON object as argument for
'-device' which will also become the only syntax considered stable by
qemu in the future.
Since libvirt was recently converted to generate the properties via JSON
to begin wit we can start using it on the commandline as well, by simply
enabling the QEMU_CAPS_DEVICE_JSON capability, which we do by probing
for the 'json-cli' feature flag of 'device_add'.
Normally a change which changes a commandline output should be happening
only after the impacted real-caps test files are forked in the version
preceding the change, but in this case it's not necessary as the logic
for generating the device properties stays identical and we just change
the output format (avoid conversion). Additionally we still have a lot
of tests validating the conversion to the old commandline options.

Commit 58ba0f6a3d7342fba29edbbf2bb9cb5497c870e5 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.

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.

The capability name piix4-acpi-root-hotplug-en is not conventional and
appreared to be confusing to some. "en" suffix is also incorrect as the
capability in qemu is used to both enable and disable hotplug on the pci root
bus on the i440fx. Hence, rename it to piix4.acpi-root-pci-hotplug so that it
is clearer, less confusing and more accurate.
