rewritten several functions from calib3d: findhomography, findfundamentalmat, findessentialmat, estimateaffine3d, computecorrespondepilines, convert points{to/from}homogeneous to C++.

Changed RANSAC Homography estimation for speed. Each minimal set is checked for consistency before actually fit a candidate homography.

fixed 8-point case in findFundamentalMat (ticket #1262). findFundamentalMat needs to be rewritten actually (as well as findHomography)

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.

switched from 8-point kernel to 7-point kernel in the fundamental matrix estimator (fixes some corner cases; see ticket #434)

added more helper macros to the function declarations, to assist the Python wrapper generator. Fixed memleak in Mat::operator()(Range,Range) and the related functions (Mat::row, Mat::col etc.)
