fixed difference between SSE2 and C branches of StereoBM; they should now produce absolutely the same results

This should allow many algorithms to take advantage of more parallelization
technologies.

This also fixes few clang build errors

Made all STL usages explicit to be able automatically find all usages of
particular class or function.

fixed parallel block matching stereo correspondence algorithm (ticket #997; thanks to jbieger for the patch)

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.

updated 3rd party libs: CLapack 3.1.1.1 => 3.2.1, zlib 1.2.3 => 1.2.5, libpng 1.2.x => 1.4.3, libtiff 3.7.x => 3.9.4. fixed many 64-bit related VS2010 warnings

fixed the output disparity at the extreme cases (minDisparity or minDisparity + numOfDisp - 1). Thanks to Patrick Mihelich for the report (trac #395)
