Previously request.headers was a normal dict (albeit with the request.add_header interface) which meant that some code paths would do case-sensitive matching, for example remove_post_data_parameters which tests for 'Content-Type'. This change allows all code paths to get the same case-insensitive treatment. Additionally request.headers becomes a property to enforce upgrading it to a CaseInsensitiveDict even if assigned.
