Implement getCookies, getLocalPort, and getLocalAddr methods in RequestWrapper

[marinedayo]

Logback Access 2.0.1 and Jetty 12.

The methods getCookies, getLocalPort, and getLocalAddr currently exist within the RequestWrapper class but do not return meaningful data as one might expect.

These methods will be used in my project and I expect to improve them.
Moreover, the improvements to getCookies and getLocalPort methods are useful as they correlate with the values used in logback-access's pattern layouts, such as %reqCookie for cookies and %localPort for the local port. (For some reason, %localIP works without the getLocalAddr implementation.

I propose the following changes:

• getCookies(): This method should be improved to convert and return an array of Cookie objects, derived from the List<HttpCookie> returned by Request::getCookies.
• getLocalPort(): By using Request::getLocalPort, this method could be improved to return the port number.
• getLocalAddr(): Similarly by using Request::getLocalAddr, this method could be improved to return the local address.

Thank you for your comments. I am looking forward to your PRs.

Please add units tests where possible.

Thank you. I'll try it.

I found a issue while considering tests for getCookies().

• AccessEvent cannot return cookies when Jetty Request is recycled #11

@ceki Thank you so much. But, I have a exception.

I would suggest using toArray with a type instead.
