This is part of a series of patches deprecating implicit conversions
of QAtomic<T> variables to T.
Use relaxed atomic loads and stores on the 'isDebugging' variable. The
old code used the implict conversions to and from int and therefore
loadAcquire/storeRelease. Here, the int is the only value, it's not
guarding the construction of any other data, so relaxed loads and
stores suffice.
A further optimization would be to make the initial value of
isDebugging 0, to send it into the BSS instead of the TEXT/DATA
segment, but seeing as this is just compiled in for the auto-tests,
this patch leaves that particular change for another round (or never).

CMake silently drops empty list items when passing ${someVar} to a
function unquoted. The versionless wrapper functions typically use
${ARGV} or ${ARGN} to pass through arguments from the caller to the
versioned implementation, but this doesn't preserve empty arguments.
For qt_add_dbus_adaptor() in particular, this was problematic because
that meant arguments after the empty arg effectively "moved left" and
were interpreted as the wrong arguments.
Use named arguments and pass through each one explicitly for the
qt_add_dbus_adaptor(). This takes advantage of the implementation of
the versioned function, which also checks each optional positional
argument explicitly. We can only do this because we know the upper
bound on the number of arguments, so it is possible to represent each
argument with its own variable. A more general solution that didn't
need to know the number of arguments would require the
cmake_language(EVAL) command, but that requires CMake 3.18 or later.

Using function instead of macro prevented the wrappers from being able
to pass back any variables set in the wrapped function. In some cases,
these variables were being explicitly passed back to the caller, but
that isn't needed if you just make each wrapper a macro. This also
makes things more future-proof because any newly introduced output
variables will work without having to update the wrappers.

This function returns the metatype corresponding to the metaobject, or
an invalid metatype for namespaces.
This works as follows: First we increment the metaobject revision for
new metaobjects. Metaobjects with older revisions are handled by doing a
lookup by name. That fallback is also used for dynamic metaobjects (from
QtDBUS and those created by QMetaObjectBuilder).
For new metaobjects, we store the metatype in its metatype array, behind
the property metatypes. This avoids any changes to the property and
method metatype extraction logic: For properties, the metatype access
does not change, as the new metatype is after their metatypes. For
method metatypes, we already have an indirection layer (using offsets),
so by adjusting those offsets by one, the same logic keeps working.
To distinguish between namespaces and dynamic metaobjects, namespaces
store the metatypeinterface pointer for void in the metatype array,
whereas dynamic metaobjects store a nullptr.
One nice additional benefit is that this simplifies the generator logic
in moc, as the metatype array is now never empty.
