Antti Kokko bbfccc7135 Update copyright headers
Qt copyrights are now in The Qt Company, so we could update the source
code headers accordingly. In the same go we should also fix the links to
point to qt.io.

\brief The QMediaControl class provides a base interface for media service controls.
Media controls provide an interface to individual features provided by a
media service. Most services implement a principal control which exposes
the core functionality of the service and a number of optional controls which
expose any additional functionality.
A pointer to a control implemented by a media service can be obtained using
the \l {QMediaService::requestControl()} member of QMediaService. If the
service doesn't implement a control it will instead return a null pointer.
\snippet multimedia-snippets/media.cpp Request control
Alternatively if the IId of the control has been declared using
Q_MEDIA_DECLARE_CONTROL the template version of
QMediaService::requestControl() can be used to request the service without
explicitly passing the IId or using qobject_cast().
\snippet multimedia-snippets/media.cpp Request control templated
Most application code will not interface directly with a media service's
controls, instead the QMediaObject which owns the service acts as an
intermediary between one or more controls and the application.

/*!
\macro Q_MEDIA_DECLARE_CONTROL(Class, IId)
\relates QMediaControl
The Q_MEDIA_DECLARE_CONTROL macro declares an \a IId for a \a Class that
inherits from QMediaControl.
Declaring an IId for a QMediaControl allows an instance of that control to
be requested from QMediaService::requestControl() without explicitly
passing the IId.
