ENH: new CMake variable (OTB_USE_JPEG2000_TESTING) to activate jpeg2000 tests even when the JPEG2000ImageIO is disabled

No more use of ITK filters itkScalarImageToCooccurrenceMatrixFilter and itkHistogramToTexturesFilter.
Integration of patch for pixelVarianceSquared from ITKPendingPatches/itkHistogramToTexturesFilter.hxx
Neigbhorhood window size updated for given Radius value and not creating MaskImage
Change InputImageMaximum to 255 in Testing Code and also updated
the default value of m_InputImageMaximum in ScalarImageToTexturesFilter
Changed tolerance value to 0.00001 from no tolerance

the makeOutput is overloaded but not with the same prototype

the prototype of the function is not compatible with the original function into itk:ProcessObject

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)

TEST: Adding a new test to cover the optional binsizey and binstepy of the HomologousPointsExtraction application

ENH: Adding binsizey and binstepy parameters to allow for anisotropic behaviour of the geobins mode of HomologousPointsExtraction application
