dc231a1d38 qemuxml2argvtest: Remove qemu-4.0 versions of cpu feature test cases
The cpu feature formatting doesn't change between the versions thus we
can just keep the '-latest' versions.

Prior to qemu-3.2 we'd have to disable the 'pconfig' feature explicitly
which is no longer needed with new qemu. Remove the version locked to
qemu-3.1 as the 'latest' case sufficiently handles what we want to test.

de2a338dce conf: Validate firmware configuration more thoroughly
Generally speaking, when firmware autoselection is in use we
don't want any information to be provided manually. There are
two exceptions:

  * we still want the path to the NVRAM file to be customizable;

  * using <loader secure='yes'/> was how you would ask for a
    firmware that implements the Secure Boot feature in the
    original approach to firmware autoselection, so we want to
    keep that working.

Anything else should result in a descriptive error.

161b31f958 conf: Reject enrolled-keys=yes with secure-boot=no
This combination doesn't make sense and so the firmware
autoselection logic will not be able to find a suitable firmware,
but it's more user-friendly to report a detailed error upfront.

Note that this check would ideally happen in the validate phase,
but if we moved it there we would no longer be able to
automatically enable secure-boot when enrolled-keys=yes. Since
the combination never resulted in a working configuration, the
chances of this causing real-world VMs to disappear are
extremely low.

a678430492 testutilsqemu: introduce ARG_CAPS_HOST_CPU_MODEL
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".

from the binary itself (which also links with
