Catched on Ubuntu 12.04 with FFMPEG:
  codec:                     YES (ver 53.35.0)
  format:                    YES (ver 53.21.1)
  util:                      YES (ver 51.22.3)
  swscale:                   YES (ver 2.1.0)
  resample:                  NO
  gentoo-style:              YES

it is new'ed but never deleted. However it does not need to be global or
heap allocated in the first place.

Corrected typo and unused imports

OPENCV_IPP env var now allows to select IPP architecture level for IPP9+;
IPP initialization logic was unified across modules;

HAVE_IPP_ICV_ONLY will be undefined if OpenCV was linked against ICV packet from IPP9 or greater. ICV9+ packets will be aligned with IPP in OpenCV APIs
This will ease code management between IPP and ICV

IPP_VERSION_MAJOR * 100 + IPP_VERSION_MINOR*10 + IPP_VERSION_UPDATE
to manage changes between updates more easily.

IPP_DISABLE_BLOCK was added to ease tracking of disabled IPP functions;

Previously, there's no way to the user see the found corners, i've changed that.

In a cout, are write that: "average reprojection err = "
But it isn't a "reprojection error" at all, it is a mean of each EPIPOLAR error, wich occur when the product x' * F * x is not equal to zero.
(x and x' are the same points in the right and left scene)
(the RMS that explain the average absolute reprojection error is given by the return of the stereoCalibrate() function)

At least, i think it's interesting to initialize the camera matrices before.

Thank you all for this amazing code. Apologize my weak english.

Minor changes to IPP implementations;
