This is a follow-up to bug 1409249. There are a lot of places where our
factory singleton constructors either don't correctly handle their returned
references being released by the component manager, or do handle it, but in
ways that are not obvious.
This patch handles a few places where we can sometimes wind up with dangling
singleton pointers, adds some explanatory comments and sanity check
assertions, and replaces some uses of manual refcounting with StaticRefPtr and
ClearOnShutdown.
There are still some places where we may wind up with odd behavior if the
first QI for a getService call fails. In those cases, we wind up destroying
the first instance of a service that we create, and re-creating a new one
later.

nsIEditorSpellCheck still uses wstring. We should replace it with AString
to avoid additional memory allocation.

Although nsIEditActionListener::WillInsertNode() nobody implements actually,
we should remove it in a follow up bug.
nsIEditActionListener::DidInsertNode() is implemented only by HTMLEditRules.
So, if we make it not use nsIEditActionListener, we can remove it too.
However, keep it for now.
On the other hand, they don't need to receive index of the insertion point.
WillInsertNode() needs next sibling of the insert point, but DidInsertNode()
needs nothing because listener can compute it with new inserted node.

Remove the headers included for "backwards compatibility" and just include them
where required.

No one uses nsIInlineSpellChecker.spellCheckAfterEditorChange from script.
So I think we can mark this interface as noscript.
Since this method is scriptable, we need QI to get nsIDOMNode. If we can
change to noscript, it can reduce QI to get nsIDOMNode.

nsIEditActionListner::DidSplitNode() takes 4 arguments, the right node,
old offset in the old right node before splitting, the new left node and
nsresult.
Computing offset for this doesn't make sense because it's always same as
the length of the left node. Additionally, nobody currently use nsersult.
So, we can get rid of it now.
Fortunately, nobody including comm-central and BlueGriffon implements
WillSplitNode(). So, we can get rid of it. However, removing interface
method should be done in a follow up bug. So, we can remove offset computation
in EditorBase::SplitNode() completely in the future.

nsIEditActionListener::WillCreateElement() and
nsIEditActionListener::DidCreateElement() are implemented only by m-c.
So, we can remove a set of container node and offset in it from their argument.
Instead, WillCreateElement() should take a node which will be next sibling of
the new node.
Note that only implementation of them is, HTMLEditRules::DidCreateElement().
So, we can get rid of them and can call HTMLEditRules::DidCreateElement()
directly from EditorBase::CreateNode(). However, such change should be done
in another bug which checks all nsIEditActionListener method implementations.

This makes the code nicer. In particular, it removes many getter_Copies()
calls. The patch also converts a lot of nsCStrings to nsAutoCString, which will
avoid heap allocation in the common case.
The patch also renames PREF_CopyCharPref() as PREF_GetCStringPref(), because
it's actually getting a string, not a char, and that matches the existing
GetCString() and GetDefaultCString() methods. Correspondingly, it also renames
PREF_SetCharPref() as PREF_SetCStringPref().
The |aPrefName| arguments in nsIPrefBranch.idl remain as |string| because they
almost always involve passing in C string literals, and passing "foo" is much
nicer than passing NS_LITERAL_CSTRING("foo").
It's worth noting that early versions of this patch used |AUTF8String| instead
of |ACString|. But it turns out that libpref stores prefs internally as Latin1.
And |ACString| is compatible with Latin1 but |AUTF8String| isn't, because
non-ASCII Latin1 strings are not valid UTF-8!

Right now, NS_GENERIC_FACTORY_SINGLETON_CONSTRUCTOR expects singleton
constructors to return already-addrefed raw pointers, and while it accepts
constructors that return already_AddRefed, most existing don't do so.
Meanwhile, the convention elsewhere is that a raw pointer return value is
owned by the callee, and that the caller needs to addref it if it wants to
keep its own reference to it.
The difference in convention makes it easy to leak (I've definitely caused
more than one shutdown leak this way), so it would be better if we required
the singleton getters to return an explicit already_AddRefed, which would
behave the same for all callers.
This also cleans up several singleton constructors that left a dangling
pointer to their singletons when their initialization methods failed, when
they released their references without clearing their global raw pointers.
