Co-occurrence Matrix computation using itkScalarImageToTexturesFilter has been replaced
using a different technique which reduces the computation time. This was used also in
ScalarImageToTexturesFilter class. Also number of iterations over the histogram
has been reduced to minimum and replaced with co-occurrence indexed list iteration
wherever possible. Maximum value of for grey level images was corrected to 255
in the Testing code.

KWSys modification need to avoid dl_close problem is done in the ITK package provided by OTB Team on Ubuntu and the modifcation is also done in the external ITK used by the OTB dashboard build on dora

TEST: duplicating a baseline file into input for RefineSensorModel and GenerateRPCSensorModel applications, so as to avoid dependency of tests to baseline changes

on win platform, ITK cannot configure internal FFTW and OSGeo4W one is not compatible

WIP: warn user during cmake configuration that USE_EXTERNAL_ITK and USE_EXTERNAL_LIBKML does not match (bug 879/896)
