Implement RFC 59.1 : GDAL/OGR utilities as a library

For GDAL v2.1 the source code of the utilities are moved to the core of GDAL: https://trac.osgeo.org/gdal/wiki/rfc59.1_utilities_as_a_library

MapWinGIS has implemented several GDAL Utilities, like gdalwarp and gdaltranslate by copying their code. This is no longer needed and MapWinGIS should move to the library version of the utilities.
