Move VTK_(MAJOR|MINOR|BUILD)_VERSION out of "CMakeLists.txt" into dedicated file "CMake/vtkVersion.cmake". Move the preprocessor macros from "vtkConfigure.h" to new configured header "vtkVersionMacros.h". This avoids rebuilding everything when the version number changes. Include the new header from the old location to provide the macros for compatibility unless VTK_LEGACY_REMOVE is ON. Define the BUILD version to be a date during development and the patch level for releases (or during preparation of one as we are currently). The CMake package version file (VTKConfigVersion.cmake) already does this so make the C++-presented version consistent with it. Add a "CMake/vtkVersion.bash" script to help a nightly robot update the build version when it is a date. This replaces KWSys DateStamp for VTK. Compile the wrapping parser with only the major and minor version number components instead of the full version number. This avoids causing a full rebuild of all wrappers whenever the build version component changes. The wrapper only needs the version to provide its --version option anyway. Teach the documentation generation scripts to extract the VTK version numbers from the new version file. Drop the separate revision file infrastructure because everything is now in one version file. Also remove unused file CMake/VTKVersionMacros.cmake. Change-Id: If988b32c738e6161237f7e3edaff49e75cb15b25
