A function may almost always have static storage duration, but that
does not necessarily mean that we can store and load pointers to them
without memory ordering. Play it safe and use store-release and
load-acquire for them (which combines to ordered for the fetchAndSet
call in qInstall*Handler(), as we don't know what the caller will do
with the returned function pointer).
Also change the initial value of the atomic pointer to nullptr.
Nullptr already signified the default handler in qInstall*Handler(),
so the API doesn't change. But by using nullptr to mean default, we
place these variables in the BSS segment instead of TEXT, save dynamic
init, or at least a relocation, and we dodge the smelly comparison of
function pointers, using comparison against nullptr instead.
Also, as a drive-by, put the call to ungrapMessageHandler() in a
scope-guard. Both the message handler, as well as the Qt code calling
it (toLocal8Bit()!), may throw, and that would stop all further
logging.
The code still has one problem: When a logging action is underway, and
another thread exchanges the message handler, we might still execute
code in the old handler. This is probably not a problem in practice,
since no-one will use a dynamically-compiled function for logging
(right? :), but should probably be documented or fixed. This patch
does not address this issue, though.

... 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.

it might be arranged that directory listings will be generated in

the existing behavior, but the user can override the guessing by

expected, a vector would still be preferable over the per-element

Because std::vector doesn't have pop_front(), I took the liberty of
making the dequeue code easier to read by using find_if with an
aptly-named lambda.
