03828af3af qemu: Introduce virQEMUCapsProbeCPUDefinitionsTest
It is a tiny wrapper around virQEMUCapsProbeQMPCPUDefinitions which will
soon get private parameters and thus it cannot be exposed outside
qemu_capabilities.

Some callers of virQEMUCapsGetCPUDefinitions will need to filter the

e20a11eecf qemu: Copy CPU models in virQEMUCapsGetCPUDefinitions
Rather than returning a direct pointer the list stored in qemuCaps the
function now creates a new copy of the CPU models list.

The main purpose of this seemingly useless change is to update callers
to free the result returned by virQEMUCapsGetCPUDefinitions because the
internals of this function will change significantly in the following
patches.

67a4dcc151 qemu_monitor: use cpu def instead of char for expansion
When expanding a CPU model via query-cpu-model-expansion, any features
that were a part of the original model are discarded. For exmaple,
when expanding modelA with features f1, f2, a full expansion may reveal
feature f3, but the expanded model will not include f1 or f2.

Let's pass a virCPUDefPtr to the expansion function in preparation for
taking features into consideration.

600462834f Remove all Author(s): lines from source file headers
In many files there are header comments that contain an Author:
statement, supposedly reflecting who originally wrote the code.
In a large collaborative project like libvirt, any non-trivial
file will have been modified by a large number of different
contributors. IOW, the Author: comments are quickly out of date,
omitting people who have made significant contribitions.

In some places Author: lines have been added despite the person
merely being responsible for creating the file by moving existing
code out of another file. IOW, the Author: lines give an incorrect
record of authorship.

With this all in mind, the comments are useless as a means to identify
who to talk to about code in a particular file. Contributors will always
be better off using 'git log' and 'git blame' if they need to  find the
author of a particular bit of code.

This commit thus deletes all Author: comments from the source and adds
a rule to prevent them reappearing.

The Copyright headers are similarly misleading and inaccurate, however,
we cannot delete these as they have legal meaning, despite being largely
inaccurate. In addition only the copyright holder is permitted to change
their respective copyright statement.

9cf38263d0 Switch from yajl to Jansson
Yajl has not seen much activity upstream recently.
Switch to using Jansson >= 2.5.

All the platforms we target on https://libvirt.org/platforms.html
have a version >= 2.7 listed on the sites below:
https://repology.org/metapackage/jansson/versions
https://build.opensuse.org/package/show/devel:libraries:c_c++/libjansson

Additionally, Ubuntu 14.04 on Travis-CI has 2.5. Set the requirement
to 2.5 since we don't use anything from newer versions.

Implement virJSONValue{From,To}String using Jansson, delete the yajl
code (and the related virJSONParser structure) and report an error
if someone explicitly specifies --with-yajl.

Also adjust the test data to account for Jansson's different whitespace
usage for empty arrays and tune up the specfile to keep 'make rpm'
working when bisecting.

Some tests require JSON_MODELS to be parsed into qemuCaps and applied
when computing CPU models and such test cannot succeed if QEMU driver is

appropriate parts if building without QEMU.

On the other hand, CPU tests with JSON_MODELS should succeed even if
model definitions from QEMU are not parsed and applied. Let's explicitly
test this by repeating the tests without JSON_MODELS set.

This fixes the build with QEMU driver disabled, e.g., on some
architectures on RHEL/CentOS.

8e72c612fe cputest: Add query-cpu-definitions reply for Xeon-E7-4830
This CPU was incorrectly detected as SandyBridge before because the
number of additional <feature> elements was the same for both
SandyBridge and Westmere CPU models, but SandyBridge is newer (the CPU
signature does not help here because it doesn't match any signature
defined in cpu_map.xml). But since QEMU's version of SandyBridge CPU
model contains xsaveopt which needs to be disabled, Westmere becomes the
best CPU model when translating CPUID data to virCPUDef. Unfortunately,
this doesn't help with translating the data we got from QEMU and the CPU
model is still computed as SandyBridge in this case.
