A little change on two http.client.Request modifiers

[Danilo Reinert]

Currently I'm using the http.client.Request class without the RequestBuilder for a project I'm working on, and I need to change the access level of two members from package to public: L148 (Ctor accepting a XMLHttpRequest, a timeout and a callback) and L233 (method to be called when the XHR ready state changes to 4).

So I don't have to override the class and relying on classpath tricks, considering I'm developing a public library, I wonder if there is any problem making this change in the original class.

Thanks.
