Structural improvements for request handling (issue #1044)

- Add new CefRequestContext and CefRequestContextHandler classes.
- Add CefRequestContext argument to CefBrowserHost static factory methods.
- Move GetCookieManager from CefRequestHandler to CefRequestContextHandler.
- Use BrowserContext as the root proxy object for network requests.
- Move accessors for CefBrowserMainParts members from CefContext to CefContentBrowserClient.
