Subject: [PATCH] Send out progress callbacks sooner.

- as soon as the NSURLConnection gets initialized
- helps to allocate and show progress indication sooner and prevent large delays without progress indication (for example when the server takes long to respond)
- estimated size is always 0 at this point, clients can use this to decide if they want to handle this callback or skip it
