... and use a variant of the QString::multiArg() trick to pass the
variable number of arguments into an out-of-line function.
The idea of this patch is to make the lowly asyncCall() and call()
functions the principal interface for DBus calls again.
Currently, it is more efficient to build up a QList<QVariant> and pass
that to the *WithArgumentList() methods. With more efficient, I mean
that the equivalent calls with QList expand to less client code,
probably because of the need to construct eight QVariant instances,
destroy them again, and then take the hit for a function call with so
many arguments, which can all but be efficient.
Consequently, when porting the NM bearer plugin to use call() instead
of callWithArgumentList(), text size increased by ~3KiB on my machine.
So, looking for a way to avoid the overhead of so many default
arguments, while at the same time allowing to pass even more arguments
than the predefined eight, I considered the QString::arg() method, but
discarded it because it does not scale to arbitrarily
(ie. SEP-limited) many arguments.
Variadic templates scale to SEP-limited many arguments, but they are
templates and deduce the exact type, so constraining the template to
only QVariants would have broken all users of the API which pass
non-QVariants and expect an implicit con- version to resolve the call.
So I decided to make a virtue of necessity, accept all argument types
and convert them to QVariant when constructing the
QString::multiArg()-inspired QVariant array.
To bring this patch to its consequential end would require to pass the
arguments as arrays instead of QLists, but to get a feeling of how
much impact this new API has, I backed the new implementation by
converting the array to a QList and calling the *WithArgumentList()
methods.
The result is, if I may say so, satisfying. Said bearer plugin drops
from +3KiB (baseline: callWithArgumentList()) to -5KiB (2.0% and 3.2%,
resp.); the (unmodified) connman bearer plugin, which already used
call(), dropped by almost 6KiB (2.5%).
While GCC can deal with the zero-sized array in a nullary call to the
variadic templates, MSVC cannot, so an extra overload provides an
alternative for zero arguments.
[ChangeLog][QtDBus][QDBusAbstractInterface] The call() and asyncCall()
methods now accept more than eight QVariant arguments.

The current code fetches currentOwner in the constructor, then sets up
a connection between a service watcher and _q_serviceOwnerChanged() in
initOwnerTracking(). But an owner change notification could arrive
after we fetch the current owner and before the connection is made.
In this case the owner change notification will be lost, and the
interface will keep reporting being invalid permanently.
The fix is to delay initializing currentOwner until after the connection
is made.

Normally, disconnectNotify() is called at the end of QObject::disconnect
and all the locks have been dropped. That is not the case for the
QObject destructor, so we need to deal with the fact that it there may
be some locks held.
I didn't catch this issue during testing because it depends on the
pointer addresses of the object being destroyed and that of the
QDBusAbstractInterface sender object, as we use one global, non-
recursive mutex pool. For the same reason, this patch is not testable.
The fix is simple: we don't need to remove the relay rules immediately.
It's ok for them to happen later, since the worst case scenario is that
we'll receive a few more signals than we have objects to deliver them
to. If that happens, we'll do a little more work than we have to. But in
the normal case, the amount of work is the same and we get the benefit
of returning more quickly from the destructor. What's more, if the
QDBusAbstractInterface object also gets destroyed, the events are
deleted and QDBusConnectionPrivate will clean everything up.

The meta-call convention for reading properties differs between Qml and QDBus.
QML expects only to provide a pointer to the return value in args[0]. That is
also how the metacall was originally introduced in Qt 4. QDBus also expects
that the caller allocates a QVariant and provides a pointer to it in a[2], in
addition to a[1] being a pointer to an int that is used to report where the
return value can be found (in where a[0] points to or the variant in a[1]) -
this is useful to report errors when reading the property by clearing the
variant.
For performance reasons, QML avoids the creation of a QVariant when reading
properties. As however QDBus expects it, a crash occurs.
This patch changes the QDBus metacall implementation to not rely on the caller
to provide a QVariant.

There has been a latent bug forever in QtDBus that would make a signal
disconnect actually disconnect too much. The reason is that
disconnectNotify() is called every time a signal is disconnected from
a receiver, but that doesn't mean it was the last connection.
This test checks whether disconnecting from voidSignal() to our test
receiver will also disconnect from exitLoop(). If it does, we'll get a
timeout. I could have implemented it with two receivers, but in the
buggy case, it would always fail first in the timeout verification.

The QMetaMethod::signature() method returns a const char pointer.
Changing the return type to QByteArray can lead to silent bugs due to
the implicit conversion to char *. Even though it's a source-
incompatible change, it's therefore better to introduce a new
