Some QVariant's like QModelIndex cannot be streamed in a meaningful way:
QDataType::save() will return false for them. However, this leads to a
qWarning and Q_ASSERT in QVariant::operator<<().

To prevent this we're calling QDataType::save() manually beforehand. We
however throw away the result if it succeeds, and still call
QVariant::operator<<() to get the benefits of the QDataStream version
handling.

The alternatives would be to make QVariant::operator<<() not assert,
or blacklist all known types with problems manually. Both seem to
be difficult though ...

[ChangeLog][QtQml][Important Behavior Changes] When a JavaScript object/array
is passed to C++ through a QVariant, the engine no longer immediately converts
the object recursively into a QVariantMap or QVariantList but instead stores
a QJSValue in the QVariant. This prevents a loss of data when the JS object
contains non-primitive types such as function objects for example. Code that
expects the variant type to be exactly QVariant::Map or QVariant::List may
need to be adapted. Registered conversion functions however ensure that code
that merely calls toMap() or toList() continues to work.

The debug services generally behave in one of two ways when initializing:
Either they block the initializing thread until some configuration is
passed over the network or they just go on. By introducing a generalized
configurable debug service the various ways of waiting on initialization
are cleaned up. The API defined for it also allows for engine-specific
initialization.

The QQmlData hooks signalEmitted() and receivers() now receive the
index in the signal index range (i.e., excluding non-signal methods).
This was done to avoid Q(Meta)Object having to compute the class's
method offset; the signal offset should be sufficient for everyone.

This required adapting QQmlNotifier, QQmlBoundSignal,
QQmlPropertyCache and friends to use the signal index range whenever
a property's notify signal is involved in the internal connection
lists and property captures.

Using the signal index range also reduces the memory used for
NotifyList::notifies, since useless entries for non-signal methods
will no longer be created.

QMetaMethod::signature() has been renamed to methodSignature(), and
it now returns a QByteArray. Also, the new function
QMetaMethod::isValid() should be used to determine whether a method
is valid, instead of relying on signature() returning a 0 pointer.

Where it makes sense, the existing code that was using signature()
and parameterTypes() has been changed to use the new API
QMetaMethod::name(), parameterCount(), and parameterType(int).

Also, in the new meta-object revision (7), the QMetaObject stringdata
member is now of type QByteArrayData*. QFastMetaBuilder will be
ported to generate the new format, but for now it's sufficient to
reinterpret_cast the stringdata assignment to keep it compiling.
