Turns out that it's not enough to pass the qemu:///embed root to
virQEMUDriverConfigNew(), you also have to make sure the same
string is copied into the virQEMUDriver structure yourself, and
not doing so in our case resulted in the cleanup never happening
and in distcheck failing because of that.
On the other hand, actually setting config->embeddedRoot would
result in different paths being generated for each test run, which
would obviously break qemuxml2argvtest, so that's not an option
either.
This reverts commit d98cc1968e.

Now that the QEMU driver natively supports storing all its runtime
data inside an arbitrary directory, we can avoid having multiple
copies of the same logic in the test suite.

With NVMe disks, one can start a blockjob with a NVMe disk
that is not visible in domain XML (at least right away). Usually,
it's fairly easy to override this limitation of
qemuDomainGetMemLockLimitBytes() - for instance for hostdevs we
temporarily add the device to domain def, let the function
calculate the limit and then remove the device. But it's not so
easy with virStorageSourcePtr - in some cases they don't
necessarily are attached to a disk. And even if they are it's
done later in the process and frankly, I find it too complicated
to be able to use the simple trick we use with hostdevs.

Move QEMU caps validation of qemuBuildHostdevCommandLine() to
qemuDomainDeviceDefValidateHostdev() and qemuDomainMdevDefValidate(),
allowing them to be validated at domain define time.
Tests were adapted to consider the new caps being needed in
this earlier stage.

As part of a goal to eliminate the need to use virCapsPtr for anything
other than the virConnectGetCapabilies() API impl, cache the host arch
against the QEMU driver struct and use that field directly.
In the tests we move virArchFromHost() globally in testutils.c so that
every test runs with a fixed default architecture reported.

Some of our tests try to validate domain XMLs they are working
with (not intentionally, simply because they call top level
domain XML parse function). Anyway, this implies that we build
domain capabilities also - see
virQEMUDriverGetDomainCapabilities(). And since some domain XMLs
are type of 'kvm' the control gets through
virQEMUCapsFillDomainCaps() and virHostCPUGetKVMMaxVCPUs() to
opening /dev/kvm which may be missing on the machine we're
running 'make check'.
Previously, we did not see this issue, because it was masked. If
building domain capabilities failed for whatever reason, we
ignored the failure. Only v5.9.0-207-gc69e6edea3 uncovered the
problem (it changed reval from 0 to -1 if
virQEMUDriverGetDomainCapabilities() fails). Since the referenced
commit is correct, we need to mock access to /dev/kvm in our
tests.

In preparation libtool "-module" flag removal, add lib prefix to all
mock shared objects.
While at it, introduce VIR_TEST_MOCK macros that makes path out of mock
name to be used with VIR_TEST_PRELOAD or VIR_TEST_MAIN_PRELOAD. That,
hopefully, improves readability, reduces line length and allows to
tailor VIR_TEST_MOCK for specific platform if it has shared library
suffix different from ".so".

This code snippet has clearly been cargo-culted, and all its
instances can be safely dropped seeing as 1) a much better
way to handle the scenario in C programs would be to pass the
value via the preprocessor, and 2) the value is actually not
used anywhere after being defined.

All of the ones being removed are pulled in by internal.h. The only
exception is sanlock which expects the application to include <stdint.h>
before sanlock's headers, because sanlock prototypes use fixed width
int, but they don't include stdint.h themselves, so we have to leave
that one in place.

Move the qemuCaps checks over to qemuDomainControllerDefValidatePCI.
This requires two test updates in order to set the correct capability
bit for an xml2xml test as well as setting up the similar capability
for the pseries memlocktest.
virDomainDef is not an instance of virObject thus
virObjectUnref() is not the correct function to be called.

All the pieces are now in place, so we can finally start
using isolation groups to achieve our initial goal, which is
separating hostdevs from emulated PCI devices while keeping
hostdevs that belong to the same host IOMMU group together.
