reverts CUDA related stuff of commit ff0167b9

Update code after solvePnP and solvePnPRansac InputOutputArray changes

optflow: RLOF fixes (python-binding, status flag, flat textures) (#2097)

* * Bugfix for python-binding related to issue #2094. Copying the prevPtsMat to prevPoints was broken, when using python-binding.

* * Connect the blurred image correctly to CROSS support region segmentation. This allows to compute more robust support region shapes. Commit refers to issue #2094.

* * Bugfix to avoid the unintended assertion on flat textures discussed in issue #2094.

* * Bugfix on SparseRLOFOpticalFlow status was wrongly to to 0 if forward backward error < threshold, which is wrong. Inequation has been corrected. Refers to in issue #2087.

* small documentation changes

* bugfix on assertions and small test changes

* fix rectifyPatch bug when patch orientation is not extracted

avoid broken min/max macros from tesseract headers

If the disparity maps have the depth CV_32F, they are wls-filtered
in `DisparityWLSFilterImpl::filter` but the result is not saved in the
OutputArray of the method. Now, the result is copied to that array.

Minor changes to the quality module to support Visual Studio 2013 (#2046)

* quality: revise syntax to support Visual C++ 2013

* quality: changes to standardize constness between Visual C++ 2013 and other compilers

Updated to use OpenCV ML, removed libsvm.  Updated model, tests and documentation.  Provided cpp samples for model training and evaluation.
