e831821cbc tests: qemu: Add helper code to lookup latest capability file
The helper iterates the directory with files for the capability test and
looks up the most recent one for the given architecture. This will allow
testing against the newest qemu capabilities so that we can catch
regressions in behaviour more easily.

7de761a67b tests: utils: Allow parsing test capability file without virCaps
virCaps was used only to propagate the host architecture, so the
function can be extracted in a way which does not require it.

d03de54e7e qemu: switch QEMU capabilities to use virFileCache
The switch contains considerable amount of changes:

  virQEMUCapsRememberCached() is removed because this is now handled
  by virFileCacheSave().

  virQEMUCapsInitCached() is removed because this is now handled by
  virFileCacheLoad().

  virQEMUCapsNewForBinary() is split into two functions,
  virQEMUCapsNewData() which creates new data if there is nothing
  cached and virQEMUCapsLoadFile() which loads the cached data.
  This is now handled by virFileCacheNewData().

  virQEMUCapsCacheValidate() is removed because this is now handled by
  virFileCacheValidate().

  virQEMUCapsCacheFree() is removed because it's no longer required.

  Add virCapsPtr into virQEMUCapsCachePriv because for each call of
  virFileCacheLookup*() we need to use current virCapsPtr.

8d04ea1661 tests/testutilsqemu: properly initialize qemu caps for tests
This removes the hacky extern global variable and modifies the
test code to properly create QEMU capabilities cache for QEMU
binaries used in our tests.

68c7011856 qemu: Store host-model CPU in qemu capabilities
Host capabilities provide libvirt's view of the host CPU, but for a
useful support for host-model CPUs we really need a hypervisor's view of
the CPU. And since the view can be differ with emulator, qemu
capabilities is the best place to store the host CPU model.

This patch just copies the CPU model from host capabilities, but this
will change in the future.

127e0b53ec testutilsqemu: Helpers for changing host CPU and arch
Changing a host architecture or a CPU is not as easy as assigning a new
value to the appropriate element in virCaps since there is a relation
between the CPU and host architecture (we don't really want to test
anything on an AArch64 host with core2duo CPU). This patch introduces
qemuTestSetHostArch and qemuTestSetHostCPU helpers which will make sure
the host architecture matches the host CPU.

63bc91eea0 tests: Prepare to have different usable GIC versions
Now that we choose the GIC version based on hardware features when
no <gic/> element has been provided, we need a way to fake the GIC
capabilities of the host.

Update the qemuxml2argv and qemuxml2xml tests to allow this.

f36c9f7b6c tests: clean up includes
After removing qemuBuildCommandLineCallbacks, testutilsqemu.h does not
need to include qemu_command.h.

Include just qemu_conf.h here and qemu_domain_address.h in files that
need it.

0da965c5e0 drop qemuBuildCommandLineCallbacks
Essentially revert commit 3a6204c which added these to allow the test
suite to pass without depending on the host system state.

Since commit 4b527c1 we already mock virSCSIDeviceGetSgName, so these
callbacks are useless.

f7dd335749 Implement infrastracture for mocking up QEMU capabilities cache
The main purpose of this patch is to introduce test mode to
virQEMUCapsCacheLookup(). This is done by adding a global variable, which
effectively overrides binary name. This variable is supposed to be set by
test suite.

The second addition is qemuTestCapsCacheInsert() function which allows the
test suite to actually populate the cache.

c563b50605 cpu: Add {Haswell,Broadwell}-noTSX CPU models
QEMU 2.3 adds these new models to cover Haswell and Broadwell CPUs with
updated microcode. Luckily, they also reverted former the machine type
specific changes to existing models. And since these changes were never
released, we don't need to hack around them in libvirt.

3a6204cbbd qemu: Add callback struct for qemuBuildCommandLine
Since 0d70656afd, it starts to access the sysfs files to build
the qemu command line (by virSCSIDeviceGetSgName, which is to find
out the scsi generic device name by adpater🚌target:unit), there
is no way to work around, qemu wants to see the scsi generic device
like "/dev/sg6" anyway.

And there might be other places which need to access sysfs files
when building qemu command line in future.

Instead of increasing the arguments of qemuBuildCommandLine, this
introduces a new callback for qemuBuildCommandLine, and thus tests
can register their own callbacks for sysfs test input files accessing.

* src/qemu/qemu_command.h: (New callback struct
                            qemuBuildCommandLineCallbacks;
                            extern buildCommandLineCallbacks)
* src/qemu/qemu_command.c: (wire up the callback struct)
* src/qemu/qemu_driver.c: (Use the new syntax of qemuBuildCommandLine)
* src/qemu/qemu_hotplug.c: Likewise
* src/qemu/qemu_process.c: Likewise
* tests/testutilsqemu.[ch]: (Helper testSCSIDeviceGetSgName;
                             callback struct testCallbacks;)

27cf98e2d1 virCaps: conf: start splitting out irrelevat data
The virCaps structure gathered a ton of irrelevant data over time that.
The original reason is that it was propagated to the XML parser
functions.

This patch aims to create a new data structure virDomainXMLConf that
will contain immutable data that are used by the XML parser. This will
allow two things we need:

1) Get rid of the stuff from virCaps

2) Allow us to add callbacks to check and add driver specific stuff
after domain XML is parsed.

This first attempt removes pointers to private data allocation functions
to this new structure and update all callers and function that require
them.
