      abi: explicitly export intended symbols and hide others · da81c86a
      Nikos Mavrogiannopoulos authored and Niels Möller's avatar Niels Möller committed
      This adds all exported symbols in the map files explicitly under
      the following rules:
       - Symbols mentioned in internal headers go in a section which is
         valid only for testing, and linking with these symbols will break
         in library updates.
       - Symbols mentioned in installed headers go in the exported sections
         and are considered part of the ABI.
       - All internal symbols move to internal headers.
       - The _nettle_md5_compress and _nettle_sha1_compress become exported
         without the _nettle prefix, due to existing usage.
