docs: Checks whether two filenames are equal after both have been normalized.
  <p>
  Both filenames are first passed to {@link #normalize(String)}.
  The check is then performed in a case-sensitive manner.
  
  @param filename1  the first filename to query, may be null
  @param filename2  the second filename to query, may be null
  @return true if the filenames are equal, null equals null
