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

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

Added print of IPP info in test log files

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.)
