In a recent commit of v8.5.0-85-g430ab88ab1 I've made domaincaps
XML report supported TPM versions. This was done by calling
virTPMSwtpmSetupCapsGet(). But this function isn't mocked and
thus domaincapstest calls the real implementation, which tries to
execute swtpm_setup binary. This fails, because
virFindFileInPath() is mocked in such way that it returns NULL
for anything else than qemu-*.
Anyway, while the real binary is not executed after all, we
should mock the function which tries to execute it so that
predictable result is returned.

When loading a latest caps for an arch for the first time the following
occurs in testQemuInfoInitArgs():
- the caps file is located. It's not in the cache since it's the first time
it's being read;
- the cachecaps are retrieved using qemuTestParseCapabilitiesArch() and
stored in the capscache;
- FLAG_REAL_CAPS is set and regular flow continues.
Loading the same latest caps for the second time the caps are loaded from the
cache, skipping qemuTestParseCapabilitiesArch(). By skipping this function it
means that it also skips virQEMUCapsLoadCache() and, more relevant to
our case, virQEMUCapsInitHostCPUModel(). This function will use the
current arch and cpuModel settings to write the qemuCaps that are being
stored in the cache. And we're also setting FLAG_REAL_CAPS, meaning that
we won't be updating the qemucaps host model via testUpdateQEMUCaps() as
well.
This has side-effects such as:
- the first time the latest caps for an arch is loaded determines the
cpuModel it'll use during the current qemuxml2argvtest run. For
example, when running all tests, the first time the latest ppc64 caps
are read is on "disk-floppy-pseries" test. Since the current host arch
at this point is x86_64, the cpuModel that will be set for this
capability is "core2duo";
- every other latest arch test will use the same hostCPU as the first
one set since we read it from the cache after the first run.
qemuTestSetHostCPU() makes no difference because we won't update the
host model due to FLAG_REAL_CAPS being set. Using the previous example,
every other latest ppc64 test that will be run will be using the
"core2duo" cpuModel.
Using fake capabilities (e.g. using DO_TEST()) prevents FLAG_REAL_CAPS to
be set, meaning that the cpuModel will be updated using the current
settings the test is being ran due to testUpdateQEMUCaps().
Note that not all latest caps arch tests care about the cpuModel being
set to an unexpected default cpuModel. But some tests will care, e.g.
"pseries-cpu-compat-power9", and changing it from DO_TEST() to
DO_TEST_CAPS_ARCH_LATEST() will make it fail every time the
"disk-floppy-pseries" is being ran first.
One way of fixing it is to rethink all the existing logic, for example
not setting FLAG_REAL_CAPS for latest arch tests. Another way is
presented here. ARGS_CAPS_HOST_CPU_MODEL is a new testQemuInfo arg that
allow us to set any specific host CPU model we want when running latest
arch caps tests. This new arg can then be used when converting existing
DO_TEST() testcases to DO_TEST_CAPS_ARCH_LATEST() that requires a
specific host CPU setting to be successful, which we're going to do in
the next patch with "pseries-cpu-compat-power9".

Add the ability to configure a qemu-vdagent in guest domains. This
device is similar to the spice vdagent channel except that qemu handles
the spice-vdagent protocol messages itself rather than routing them over
a spice protocol channel.
The qemu-vdagent device has two notable configuration options which
determine whether qemu will handle particular vdagent features:
'clipboard' and 'mouse'.
The 'clipboard' option allows qemu to synchronize its internal clipboard
manager with the guest clipboard, which enables client<->guest clipboard
synchronization for non-spice guests such as vnc.
The 'mouse' option allows absolute mouse positioning to be sent over the
vdagent channel rather than using a usb or virtio tablet device.
Sample configuration:
<channel type='qemu-vdagent'>
<target type='virtio' name='com.redhat.spice.0'/>
<source>
<clipboard copypaste='yes'/>
<mouse mode='client'/>
</source>

Until now we did 2 weird things when inserting the qemuCaps used for
individual test cases into the capability cache:
1) we inserted the same caps for all emulators
2) we always (expensively) copied them
Now when real capabilities are used we don't touch them at all just
simply inser them. This allows us one big optimization, by trading a
copy for just a virObjectRef as we can borrow the caps object to the
cache.
For fake caps we still copy them as we insert the fake machine types
into them, but second big optimization is to insert the capabilities
only for the architecture they belong to.
Additionally this commit also ensures that all other entries in the
cache for the binary are poisoned by empty caps so that it's obvious
that the test is doing the right thing.
Apart from this making actually more sense this shaves off more than 40%
of runtime from qemuxml2argvtest.
