hdf5

h5vers:
    Added code to update version strings in
    config/cmake/scripts/HDF5config.cmake.

release:
    Added options to create CMake tar.gz and zip files containing the
    HDF5 source and scripts to build and test HDF5 with cmake and ctest
    by running a single command.  These were previously assembled
    manually.

    Added a call to h5vers to set the version being released where it
    occurs in files.  In particular, the sub-release version string
    "currently under development" was not being removed from
    cpp_doc_config or HDF5config.cmake.
