Cleaning up
    
    - Fixed several issues with installed files
    - Fixed ./configure arguments - several of them where outdated or
      used wrong
    - Fixed doc packaging, primarily using %{_pkgdocdir}
    - Install management-notes.txt, which contains useful information
      about the OpenVPN management interface commands
    - Use 'make install' instead of doing it manually
    
    (based on a backport of commit f3d0d5131fc25dff2081f7259b34372d6be33f45)

      strictly needed in this package.
