Subject: * New primop builtins.filterSource, which can be used to filter files
   from a source directory.  All files for which a predicate function  
 returns true are copied to the store.  Typical example is to leave   out the
 .svn directory:

    stdenv.mkDerivation {
      ...
      src = builtins.filterSource
        (path: baseNameOf (toString path) != ".svn")
        ./source-dir;
      # as opposed to
      #   src = ./source-dir;
    }

  This is important because the .svn directory influences the hash in
  a rather unpredictable and variable way.
