    * Moved embedded external code from hbmzip library to
      separate, locally hosted library inside the 'external'
      directory. This way we keep all external code under this
      directory. This change also makes it possible to use
      custom version of this external library, via the
      HB_WITH_MINIZIP envvar.
      NOTE: Everyone using hbmzip, must now add 'minizip'
            to their lib list. (INCOMPATIBLE)
