8276774: Cookie stored in CookieHandler not sent if user headers contain cookie

[dfuch]

Hi,

Please find enclosed a patch that solves an unexpected interaction between server-set cookies and user-set cookies in the java.net.HttpClient.

In JDK 12 we fixed JDK-8213189 to allow user-supplied header to take precedence over (that is, replace) system-headers.
At the time the fact that server cookies would be added to the system-supplied headers by the CookieHandler (if present), and that a user-supplied cookie would therefore replace them (instead of simply appending to them) was overlooked.

This fix proposes to restore the behavior of JDK 11 WRT to cookies - and arrange for user-supplied cookies to be appended to server-supplied cookies.
