Bug 722872 - Part 1: Add nsITransferable::Init(nsILoadContext*), enforce that it's called in debug builds, and add nsIDOMDocument* arguments to nsIClipboardHelper methods; r=roc This patch does the following: * It adds nsITransferable::Init(nsILoadContext*). The load context might be null, which means that the transferable is non-private, but if it's non-null, we extract the boolean value for the privacy mode and store it in the transferable. * It adds checks in debug builds to make sure that Init is always called, in form of fatal assertions. * It adds nsIDOMDocument* agruments to nsIClipboardHelper methods which represent the document that the string is coming from. nsIClipboardHelper implementation internally gets the nsILoadContext from that and passes it on to the transferable upon creation. The reason that I did this was that nsIClipboardHelper is supposed to be a high-level helper, and in most of its call sites, we have easy access to a document object. * It modifies all of the call sites of the above interfaces according to this change. * It adds a GetLoadContext helper to nsIDocument to help with changing the call sites.
