cv::Complex, cv::Point_ and cv::Point3_ are moved.

This partly reverts commit 6ca61827.

HAVE_CONFIG_H -> HAVE_CVCONFIG_H

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

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

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.)
