Add a private QBindableInterface and a public QBindable<T>
class, that will be the API interface for accessing bindings
for properties in QObject.
The QBindable class gives access to all aspects of
the property related to bindings. This includes setting
and retrieving bindings, installing observers and creating
a direct binding on this property.

These look rather weird, an explicit property.setBinding() call
is simply better in this case, and also more aligned with the API
we can offer in QObject.

Add an empty QUntypedPropertyData class. This allows making
a couple of places where the system is currently using a
void * more type safe.
Also add a QPropertyData<T> as an intermediate class between
QUntypedPropertyData and QProperty. This class will get used
in a future commit to simplify storing property data separately
from the possible binding data.
Also simplify the static observer handling a bit by always
passing it a pointer to the QUntypedPropertyData instead of
some other void * that could point to anything.

Rename QPropertyBase to QPropertyBindingData, as it contains the

Enable the arrow operator for all types that could have members, so

use the less convenient myStringProperty.value().size().
Also cleaned up the rvalue ref overloads to be

return by value, for more complex types we
return a const reference.

Generalize some methods taking a QProperty<T>,

This removes some duplication between QProperty and

data in a different place.

If one needed to listen to a signal just once, one had to
store the QMetaObject::Connection object returned by connect()
and use it to disconnect the slot after the first signal
activation.
This has led to a proliferation of using wrappers (and enough
TMP); they usually look like this:
1) create a shared_ptr<QMO::Connection>, allocating its payload;
2) create a lambda, capturing the shared_ptr by value;
3) in the lambda, disconnect the connection (through the shared_ptr),
and call the actual slot;
4) connect the signal to the lambda, storing the returned
QMO::Connection into the shared_ptr.
This is expensive, error prone for newcomers, and tricky to
support as a general facility inside one's projects.
We can do better, just support single shot connections right
in QObject.
[ChangeLog][QtCore][QObject] Added the Qt::SingleShotConnection
flag. When a connection is established with this flag set,
the slot is going to be activated at most once; when the signal
is emitted, the connection gets automatically broken by Qt.

The code here represents the minimal set of functionality needed to have
a practical sequential container. The functionality is not completely
orthogonal. In particular, the index based operations could be
implemented in terms of iterator-based operations.
