e.g. <opencv2/core/core.hpp> become <opencv2/core.hpp>

Also renamed <opencv2/core/opengl_interop.hpp> to <opencv2/core/opengl.hpp>

Only the code.

added test for solvePnP
changed test for solvePnPRansac
fixed bug with mutex solvePnPRansac

replaced "const InputArray&" => "InputArray"; made InputArray and OutputArray references. added "None()" constant (no array()).

updated OpenCV version to 2.2.9; added missing cv::convertPointsHomogeneous for backward compatibility; fixed bug #952

a big patch; use special proxy types (Input/OutputArray, Input/OutputArrayOfArrays) for passing in vectors, matrices etc.

replaced alloca() (a.k.a. cvStackAlloc) with AutoBuffer or vector() everywhere. cvStackAlloc() is still defined, but we do not need alloca() anymore to compile and run OpenCV (fixes #889 and may be some others)

reworked nearly all of the OpenCV tests (except for opencv_gpu tests) - they now use the Google Test engine.

moved estimateAffine3D declaration from imgproc to calib3d, where it is really implemented (ticket #705)
