Use real properties for QSensor::bufferSize & co

The #ifdef Q_DOC hack is not really needed and was
confusing.

In addition, expose those properties to the QML API.

As a result, the backends can now listen to the
bufferSizeChanged() signal to update the buffering
while the sensor is running. This has been implemented
for the BlackBerry platform.
