Something nice we'd like to detect for array-backed containers
is if the iterator passed is a Contiguous one; if the type is also
trivially copyable / Q_PRIMITIVE_TYPE, we could memcpy() the whole
range.
However, there's no trait in the Standard to detect contiguous
iterators (the best approximation would be detecting if the iterator
is actually a pointer). Also, it's probably not smart to do the work
now for QVector since QVector needs refactoring anyhow, and this work
will be lost.

Usually, when you load a plugin, you don't want to load just any plugin
that fulfills a given interface, but rather a specific one. When loading
dynamic plugins you can differentiate the plugins by file name. This
doesn't work in the static case, and file names are also separate from
the plugin metadata shipped inside the plugin files.
To solve this problem, different hacks have been developed in various
places. QML extension plugins add a special property "uri" via the -M
option of moc, QML debug plugins expect you to add a json file with
an array of "Keys", Qt Creator plugins have a "Name" in their json
files, etc.
By allowing the identifier for the plugin to be specified inline with
the metadata declaration we can make many of the above workarounds
obsolete and provide a clean way for users to find their plugins.

QMetaObject::newInstance returns a QObject, thus it's not possible to
create a new instance of a Q_GADGET using this function. Previously, we
returned a non-null QObject pointer for such scenarios, which then
leads to crashes when one tries to use it. Now, we check whether the
meta object inherits QObject's meta object, and error out early
otherwise.

QTimer::singleShot is optimized for zero timeouts when using the API
taking a string method name. This optimization was not used for the API
taking a PMF or functor. This patch adds it, making the various API
calls behave similarly from a performance point of view.
The approach taken here requires a QObject context object. If none is
available, e.g. a nullptr was passed explicitly, or the
QTimer::singleShot(O, Functor) API was used, the optimization could
not easily be applied. This is not only bad from a performance POV,
but also poses as a potential source for heisenbugs: Using the
different API versions of QTimer::singleShot would use different code
paths internally, which then would not ensure the expected slot call
order. This problem actually existed already when mixing the
string-based slot syntax with PMF/functors in the QTimer::singleShot
API.
This patch overcomes this hurdle and fixes all of the above: When we
encounter a 0ms single shot timer, and no QObject context object is
available, we fall back to the main thread, or create a temporary
QObject for any other thread. The updated and extended benchmark
shows that this is still a significant performance improvement
over using a timer:

just min / 2; and doubling that won't overflow (which is what the test
