    Issue #6268: More bugfixes about BOM, UTF-16 and UTF-32

     * Fix seek() method of codecs.open(), don't write the BOM twice after seek(0)
     * Fix reset() method of codecs, UTF-16, UTF-32 and StreamWriter classes
     * test_codecs: use "w+" mode instead of "wt+". "t" mode is not supported by
       Solaris or Windows, but does it really exist? I found it the in the issue.
