- Fixed default duration -1 -> 0.
- Fixed a test because after pause() positionChanged is always emitted.

This follows what was done in d28c9f6a for Qt Quick Controls 2.
The latest import version (e.g. 2.11 in Qt 5.11) will automatically be
registered whenever the Qt version is bumped.

This avoids needing to wait until a new type is added (or a new
revision is added to an existing type) before being able to use the
newest Qt Quick version.

When requesting a OGL Core profile via QSurfaceFormat::setDefaultFormat (e.g. to use Qt3D advanced features),
it is no longer possible to render QML Video items. This is because the requested shaders should be _core versions.
This patch adds the core shaders so QtMultimedia stops whining, and bind textures with the proper
format, since GL_LUMINANCE and GL_LUMINANCE_ALPHA are no longer valid in OGL 4.

Added an ability to define custom pipeline.
Since new pipeline is used, playbin features will not work.

In case if there is a need to render to QML VideoOutput element.
I.e. if a pipeline is "videotestsrc ! qtvideosink" then QGstVideoRendererSink
will be used as a sink and rendering will be done by one of QSGVideoNode's.

In this case there is a need to create a pipeline after video surface is ready.

Also added an ability to override default video sink and define custom one instead.
QGstreamerVideoRendererInterface::setVideoSink() provides functionality to override default one.

CameraBin creates default (application/ogg, video/x-theora) video profile
or sets custom defined one, but ONLY on GST_STATE_CHANGE_NULL_TO_READY.

If the camera is already loaded then it is not possible to change the video profile.

Since a video profile was never defined, video/x-theora was always used to record video.

Moved setting video profile before it gets to READY.
It fixes an issue with ignoring CameraBinRecorder::applySettings().
This also changes previous behavior when video/x-theora was always used.

To apply custom video settings it requires to use QMediaRecorder::setVideoSettings
before the camera enters the READY state.
