RFR: 8133686: HttpURLConnection.getHeaderFields and URLConnection.getRequestProperties methods return field values in reverse order [v3]

[Evan Whelan]

> Hi all,
> 
> Please review this fix for which corrects the order in which field values are returned from the `HttpURLConnection.getHeaderFields` and `URLConnection.getRequestProperties` methods.
> 
> Currently, the implementation of these methods returns the values in reverse. This does not conform with the RFC2616 spec which outlines that the order of these field values should not be changed. 
> 
> Thanks,
> Evan
