release: OpenCV 3.4.16

* Fix gst error handling

* Use the return value instead of the error, which gives no guarantee of being NULL in case of error
* Test err pointer before accessing it
* Remove unreachable code

* videoio(gstreamer): restore check in writer code

-##### Issue submission checklist
-
- - [ ] I report the issue, it's not a question
-   <!--
-   OpenCV team works with answers.opencv.org, Stack Overflow and other communities
-   to discuss problems. Tickets with question without real issue statement will be
-   closed.
-   -->
- - [ ] I checked the problem with documentation, FAQ, open issues,
-       answers.opencv.org, Stack Overflow, etc and have not found solution
-   <!--
-   Places to check:
-   * OpenCV documentation: https://docs.opencv.org
-   * FAQ page: https://github.com/opencv/opencv/wiki/FAQ
-   * OpenCV forum: https://answers.opencv.org
-   * OpenCV issue tracker: https://github.com/opencv/opencv/issues?q=is%3Aissue
-   * Stack Overflow branch: https://stackoverflow.com/questions/tagged/opencv
-   -->
- - [ ] I updated to latest OpenCV version and the issue is still there
-   <!--
-   master branch for OpenCV 4.x and 3.4 branch for OpenCV 3.x releases.
-   OpenCV team supports only latest release for each branch.
-   The ticket is closed, if the problem is not reproduced with modern version.
-   -->
- - [ ] There is reproducer code and related data files: videos, images, onnx, etc
-   <!--
-   The best reproducer -- test case for OpenCV that we can add to the library.
-   Recommendations for media files and binary files:
-   * Try to reproduce the issue with images and videos in opencv_extra repository
-     to reduce attachment size
-   * Use PNG for images, if you report some CV related bug, but not image reader
-     issue
-   * Attach the image as archive to the ticket, if you report some reader issue.
-     Image hosting services compress images and it breaks the repro code.
-   * Provide ONNX file for some public model or ONNX file with with random weights,
-     if you report ONNX parsing or handling issue. Architecture details diagram
-     from netron tool can be very useful too. See https://lutzroeder.github.io/netron/
