original commit: https://github.com/opencv/opencv/commit/5bf73457431b7d2cb87ac8c107865388dbf66642

Add LOGOS (Local geometric support for high-outlier spatial verification) features matching strategy.

Cudaarithm python bindings for merge and split are inconsistent with the format of existing cuda python functions.  Split does not return its output and merg's documentation is incorrect.

Harmonise bibtex formatting. Sort entries alphabetically by the last name of the first paper author.

* ximgproc(test): createSuperpixelSLIC smoke test

* ximgproc: don't use 'operator+()' with empty cv::Mat

[moved from opencv] Merge pull request opencv/opencv#16150 from alalek:cmake_avoid_deprecated_link_private

Patch cv::cudacodec::createVideoReader() memory leak until cudacodec can be updated to miirror NVidia example code.

backport commit 13f76375

backport commit 8c092493

Fix cudacodec::VideoReader::nextFrame python bindings

* Signla to python bindings generator that nextFrame's OutputArray is a GpuMat.
Also remove duplicate test in cudacodec

* cudacodec: drop CV_GPU, wrap GpuMat only

* Make it explicit that frame in nextFrame is GpuMat and cannot be multiple types as implied by OutputArray

VLA is part of C99, but still not part of C++ standard
Replace float variable-length-arrays with unique_ptr arrays (which are
part of C++14)

not needed since we require OGRE 1.11.5 via CMake
