v2
- rebased on latest master changes
# Description
Add support for libvirt to query and cache an array of deprecated CPU features
(aka CPU properties) for the host-model. This data is queried via a full
query-cpu-model-expansion and cached in the QEMU capabilities file. This
model expansion will depend on the availability of the "deprecated-props" field
resulting from a query-cpu-model-expansion command. Currently, only s390x
supports this field.
The purpose of these patches is to make it easy for users to create guests with
a CPU model that will be compatible & migratable with future hardware.
An updated host CPU model with deprecated features paired with the policy
"disable"
may be visable via an update to the virsh domcapabilities command with the
--disable-deprecated-features flag. An example is shown below.
Note: other CPU model queries (e.g. baseline and comparison) currently do not
consider deprecated features, as their outputs do not consider feature policy.
If implementation is desired, it will require a discussion on how these
commands should report policies.
Examples:
virsh domcapabilities --disable-deprecated-features
e.g. output (trimmed):
<mode name='host-model' supported='yes'>
<model fallback='forbid'>z14.2-base</model>

New subject: [PATCH v2 1/5] qemuMonitorJSONGetCPUModelExpansion: refactor parsing functions
Refactor the CPU Model parsing functions within
qemuMonitorJSONGetCPUModelExpansion. The new functions,
qemuMonitorJSONParseCPUModelExpansionData and
qemuMonitorJSONParseCPUModelExpansion invoke the functions they
replace and leave room for a subsequent patch to handle parsing the
(optional) deprecated_props field resulting from the command.

New subject: [PATCH v2 2/5] qemu: parse deprecated-props from query-cpu-model-expansion response
query-cpu-model-expansion may report an array of deprecated properties.
This array is optional, and may not be supported for a particular
architecture or reported for a particular CPU model. If the output is
present, then capture it and store in a qemuMonitorCPUModelInfo struct
for later use.
The deprecated features will be retained in qemuCaps->kvm->hostCPU.info
and will be stored in the capabilities cache file under the <hostCPU>
element using the following format:
<deprecatedFeatures>
<property name='bpb'/>
<property name='csske'/>
<property name='cte'/>
<property name='te'/>
</deprecatedFeatures>
At this time the data is only queried, parsed, and cached. The data
will be utilized in a subsequent patch.

New subject: [PATCH v2 3/5] qemu_capabilities: query deprecated features for host-model
Add QEMU_CAPS_QUERY_CPU_MODEL_EXPANSION_DEPRECATED_PROPS for detecting
if query-cpu-model-expansion can report deprecated CPU model properties.
QEMU introduced this capability in 9.1 release. Add flag and deprecated
features to the capabilities test data for QEMU 9.1 and 9.2 replies/XML
since it can now be accounted for.
When probing for the host CPU, perform a full CPU model expansion to
retrieve the list of features deprecated across the entire architecture.
The list and count are stored in the host's CPU model info within the
QEMU capabilities. Other info resulting from this query (e.g. model
name, etc) is ignored.
The new capabilities flag is used to fence off the extra query for
architectures/QEMU binaries that do not report deprecated CPU model
features.

New subject: [PATCH v2 4/5] virsh: add --disable-deprecated-features flag to domcapabilities
Add a new flag, --disable-deprecated-features, to the domcapabilities
command. This will modify the output to show the 'host-model' CPU
with features flagged as deprecated paired with the 'disable' policy.
virsh domcapabilities --disable-deprecated-features

New subject: [PATCH v2 5/5] conf: add deprecated_features attribute
Add a new a attribute, deprecated_features='on|off' to the <cpu>
element. This is used to toggle features flagged as deprecated on the
CPU model on or off. When this attribute is paired with 'on',
deprecated features will not be filtered. When paired with 'off', any
CPU features that are flagged as deprecated will be listed under the
CPU model with the 'disable' policy.
Example:
<cpu mode='host-model' check='partial'
deprecated_features='off'/>
The absence of this attribute is equivalent to the 'on' option.
The deprecated features that will populate the domain XML are the same
features that result in the virsh domcapabilities command with the
--disable-deprecated-features argument present.
It is recommended to define a domain XML with this attribute set to
'off' to ensure migration to machines that may outright drop these
features in the future.
