    Update Doxyfile.in for current Doxygen version 1.9.5
    
    This file is now compatible up to Doxygen 1.9.5, i.e. there are
    no warnings about obsolete parameters when generating the docs.
    
    Current git 'master' of Doxygen (1.9.6: not yet released) issues
    some warnings but these will hopefully be fixed in Doxygen.
    
    Oldest tested Doxygen: 1.8.17 - older versions may emit warnings.
