When trying to attach vhost-user-blk device to virtual machine using
qemu < 4.2 libvirt would mistakenly add a scsi=off parameter, which is
not supported by qemu.

With qemu versions prior to qemu-5.0 we'll format 'scsi=off' for
virtio-blk disks, but also for vhost-user-blk. This is a bug as it's not
supported.
Add a test case to show that wrong configuration is generated by adding
running 'disk-vhostuser' test case on capabilities from qemu-4.2.
For this to be possible it's required to enable shared memory via NUMA
configuration as old QEMU's don't allow configuration of the default
memory backend. This is achieved by adding a copy of the
'disk-vhostuser' XML with NUMA enabled.

An update to meson 0.61.1 meant that it started showing warnings due to the fact
that the default for run_command's 'check' parameter is going to change. It
unveiled the fact that we were even missing that parameter in some calls where
we expected different outcome. To make sure the behaviour does not change
specify the parameter explicitly. In places where we check for the return code
the parameter should be 'false' so that meson does not fail. In all other cases
the parameter should be set to 'true' to make sure possible failure also stops
meson.
The warning in meson was added in https://github.com/mesonbuild/meson/pull/9304

The lookups in esx_vi work a bit differently that we are used to. The filters
(travelsalSpec and selectSet) choose how to look up the objects, but given a
root object the lookup lists all the objects of a requested type inside it as
well as the root object itself. We then go through the results and find the one
which has the same name as was requested. However in a case with nested folders
of a same name this could break when the first returned object in the list is
the parent folder as we'd select it only based on the name. To avoid this also
add a check that the candidate we are trying to pick is not exactly the same
object (reference) as the root object.

Turns out, the commit did more harm than good. It changed
semantics on some public APIs. For instance, while
qemuDomainGetInfo() previously did not returned an error it does
now. While the calls to virProcessGetStatInfo() is guarded with
virDomainObjIsActive() it doesn't necessarily mean that QEMU's
PID is still alive. QEMU might be gone but we just haven't
realized it (e.g. because the eof handler thread is waiting for a
