[test_server] Update test_server to handle unicode

* Use UTF-8 encoding for all HTML files, except the HTML version of
  the test suite generated with erl2html2:convert, which will have the
  same encoding as the original test suite (.erl) file.

* Encode link targets in HTML files, allowing both special characters
  like "/", "&", "?" etc, and latin1 or unicode characters.

* Use unicode modifier 't' with ~s and ~p when appropriate.

* Use unicode:characters_to_list and unicode:characters_to_binary for
  conversion between binaries and strings instead of binary_to_list
  and list_to_binary.
