The @tickpolicy member of the _virDomainTimerDef struct stores
values of the virDomainTimerTickpolicyType enum, or -1 for the
default value (when user provided no value in XML).
This is needlessly complicated. Introduce new value to the enum
which reflects the default state.

In the _virDomainTimerDef structure we have @present member which
is like virTristateBool, except it's an integer and has values
shifted by one. This is harder to read. Retype the member to
virTristateBool which we are familiar with.

The aim of virDomainChrSourceDefCopy() is to make a deep copy of
given virDomainChrSourceDef. However, some types were not copied
at all (VIR_DOMAIN_CHR_TYPE_SPICEVMC and
VIR_DOMAIN_CHR_TYPE_SPICEPORT) and some members weren't copied
either (@logfile, @logappend).
After this, there are still some members that are not copied
(seclabels and private data), but the sole caller
qemuProcessFindCharDevicePTYsMonitor() doesn't seem to care.
Therefore, just document this behavior so that future user is
aware.

Compiler isn't able to see that 'virDevMapperGetTargets' in cases e.g.
when the devmapper isn't available may not initialize the value in the
pointer passed as the second argument.
The usage 'qemuDomainSetupDisk' lead to an accidental infinite loop as
previous calls apparently doctored the stack to a point where
'g_slist_concat' would end up in an infinite loop trying to find the end
of the list.

With qemu versions prior to qemu-5.0 we'll format 'scsi=off' for

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 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.
