We could have used the new NS_NewCStringInputStream overload here, but
it seemed nicer to directly transfer ownership into the newly-created
stream. If we're going to be more efficient here, we might as well go
as far as when can without making the code too ugly.
On Mac, when dragging an image, add the image request's MIME type to
the transfer so that the MIME-extension check can be done in the
parent process to avoid content sandboxing issues.

Bug 1400459 devirtualized nsIAtom so that it is no longer a subclass of
nsISupports. This means that nsAtom is now a better name for it than nsIAtom.
MozReview-Commit-ID: 91U22X2NydP
This patch merges nsAtom into nsIAtom. For the moment, both names can be used
interchangeably due to a typedef. The patch also devirtualizes nsIAtom, by
making it not inherit from nsISupports, removing NS_DECL_NSIATOM, and dropping
the use of NS_IMETHOD_. It also removes nsIAtom's IIDs.
These changes trigger knock-on changes throughout the codebase, changing the
types of lots of things as follows.
- nsCOMPtr<nsIAtom> --> RefPtr<nsIAtom>
- nsCOMArray<nsIAtom> --> nsTArray<RefPtr<nsIAtom>>
- Count() --> Length()
- ObjectAt() --> ElementAt()
- AppendObject() --> AppendElement()
- RemoveObjectAt() --> RemoveElementAt()
- ns*Hashtable<nsISupportsHashKey, ...> -->
ns*Hashtable<nsRefPtrHashKey<nsIAtom>, ...>
- nsInterfaceHashtable<T, nsIAtom> --> nsRefPtrHashtable<T, nsIAtom>
- This requires adding a Get() method to nsRefPtrHashtable that it lacks but
nsInterfaceHashtable has.
- nsCOMPtr<nsIMutableArray> --> nsTArray<RefPtr<nsIAtom>>
- nsArrayBase::Create() --> nsTArray()
- GetLength() --> Length()
- do_QueryElementAt() --> operator[]
The patch also has some changes to Rust code that manipulates nsIAtom.

This isn't a super essential feature, and is just a change to try to bring us in
line with chromium and the spec. As this has apparent web compat issues, and
DataTransfer is a hard to test area, this patch moves the changes behind a pref,
which we can come back to turning on after we ship 57.
When dragging a `draggable=true` HTML DOM node, if no data is added to the
DataTransfer during the DragStart event, we currently cancel the drag. This is
inconsistent with Chrome's behaviour.
This patch adds a chrome-only (hidden from content) item to the DataTransfer:
application/x-moz-dummy-data. This data is added only when no other data has
been added to the DataTransfer, and the target of the dragstart event was a
draggable=true HTML DOM node.
This hidden node allows for the drag event to complete successfully, while
appearing the same as Chrome's behavior to content scripts.

application/x-moz-file entries on the clipboard are not able to be
successfully transmitted across synchronous IPC due to bug 1308007, thus
they appear as useless null files.
This patch hides those useless null files, and thus unhides image data
which may have been on the clipboard but was previously hidden by the
presence of an application/x-moz-file file

The idea is to not make consumers think about whether the principal exists or
not when the caller knows for sure that it does.
The substantive changes are in dom/bindings, nsHTMLDocument::SetDesignMode, and
around the CanUseStorage bits. Everything else is pretty mechanical.
