gecko/browser/base/content/nsContextMenu.js
Ehsan Akhgari 45fe6d3ae2 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.
