This reverts commit b741226d.

BUG: Fixing bug #983 (Split map was not correctly estimated when ImageRegion did not start at [0,0]). Added two tests for this case as well.

Following remarks from debian packagers, the ITCopyright.txt was mentioned in
several files but not available in the Copyright directory.  After contacting
the contributor Gregoire Mercier, he has suggested to harmonize the copyright for his
contributions.  Files with GET or IT copyright referenced now the
IMTCopyright.txt file (Institut Mines Telecom) which was added to the Copyright directory.

Moreover, Gregoire Mercier confirmed that he is not the author of 7 files which
are mentioning the GET or IT copyright:

Modules/Filtering/Projection/include/otbROIdataConversion.h
Modules/Filtering/Projection/include/otbROIdataConversion.txx
Modules/Segmentation/Conversion/test/otbVectorDataRasterizeFilter.cxx
Modules/Segmentation/Conversion/test/otbVectorDataToLabelImageFilterWithoutReader.cxx
Modules/Segmentation/Conversion/test/otbPolygonizationRasterizationTest.cxx
Modules/Segmentation/Conversion/test/otbVectorDataToLabelImageFilter.cxx
Modules/Segmentation/Conversion/test/otbOGRDataSourceToLabelImageFilter.cxx

Thus, the copyright was also modified for these 7 files (CNES Copyright).

Earlier one needs all otb modules to build examples. This single commit
activate an example and its related test if and only if all of its
dependent module is activated. The check for a module is done using
<Module>_LOADED cmake variable. With this change, activating
BUILD_EXAMPLES=ON works flawlessly irrespective of your build configuration.

TEST: Adding test for ImageToNoDataMaskFilter. Test is standalone and does not require ulages or baselines from OTB-Data

TEST: Adding test for ChangeNoDataFilter. Test is standalone and does not require ulages or baselines from OTB-Data

BUG: Fixing error in filter implementation: GenerateOutputInformation is called before BeforeThreadedGenerateData(), and this->GetFunctor()->m_Flags was therefore always empty
