This patch makes ContentIteratorBase, PostContentIterator, PreContentIterator
and ContentSubtreeIterator classes non-refcountable because most users can
create their instances in stack and such users may be in a hot path. So,
we can save a lot of cost of instantiation.
Unfortunately, only ScriptableContentIterator creates one of the concrete
classes and needs to destroy it properly. Therefore, its
EnsureContentIterator(), destructor, traverse and unlink code becomes messy.
However, ScriptableContentIterator was designed for automated tests and we
need to maintain it not so many times. Therefore, improvement of other
users must be worthwhiler than this demerit.

Now, all users of PostContentIterator can access it directly. This patch
makes them use the concrete class directly.

Summary: Really sorry for the size of the patch. It's mostly automatic
s/nsIDocument/Document/ but I had to fix up in a bunch of places manually to
add the right namespacing and such.
Overall it's not a very interesting patch I think.
nsDocument.cpp turns into Document.cpp, nsIDocument.h into Document.h and
nsIDocumentInlines.h into DocumentInlines.h.
I also changed a bunch of nsCOMPtr usage to RefPtr, but not all of it.
While fixing up some of the bits I also removed some unneeded OwnerDoc() null
checks and such, but I didn't do anything riskier than that.
AutoTransactionBatch, AutoPlaceholderBatch, AutoSelectionRestorer,
AutoTopLevelEditSubActionNotifier, AutoTransactionsConserveSelection and
AutoUpdateViewBatch access protected members of EditorBase. The access
scope management assume that they are used only by EditorBase or its
subclasses or TextEditRules or its inherited class (i.e., HTMLEditRules).
For guaranteeing this at build-time, we should change them to nested classes
of EditorBase. Then, EditorBase and its subclasses and friends can use them.

We should not use nsIDOMDocument if unnecessary. Because it needs QI to access
nsIDocument.

nsIClipboardDragDropHooks and nsIClipboardDragDropHookList allow XUL apps
to customize drag and drop operation and paste operation. However, this
feature was used only by ChatZilla and it doesn't work on Gecko anymore.
So, we can get rid of them from our tree.

EditorUtils::IsDescendantOf() current takes a pointer to offset or a pointer to
child content if the caller needs to know the child of the most ancestor node.
However, some callers should get a child as EditorDOMPoint or EditorRawDOMPoint.
Then, they can be used for some editor methods which need to take child node
for performance optimization.
This patch makes EditorUtils::IsDescendantOf() as only two overloads. One takes
pointer to EditorRawDOMPoint as optional out argument. The other takes pointer
to EditorDOMPoint as an out param.
Additionally, this creates new constructor of AutoTrackDOMPoint for making it
can treat EditorDOMPoint directly.

Currently, editor code uses following style (or similar style) in a lot of places:
if (foo)
{
}
else
{
}
This patch fixes this as conforming to our coding rules, i.e., it becomes:
if (foo) {
} else {
}
Additionally, this fixes other odd control statements in the files which include above issue because it's difficult to find following issues with searching the files:
* if (foo) bar;
* if (foo) { bar; }
* if (foo)
bar;
Finally, if it becomes much simpler than current code, this patch rewrites existing code with "early return style". But this case is only a few places because this is risky.

In our coding rules, variable names of nsresult should be rv. Indeed, when you see |rv| in the code, you must assume that its type if nsresult.
However, a lot of code under editor/ uses |res| for the variables of nsresult. Let's replace |res| with |rv|.
And this patch improves following points:
1. When |rv| is set in both |if| and |else| block and they are check outside of them, this moves the check into each |if| and |else| block because even if the failure is notified with warning, you cannot see which case was performed and failed. This change makes it clear.
2. When |return rv;| returns non-error code because |rv| is checked with NS_ENSURE_SUCCESS() immediately before, setting replacing it with |return NS_OK;| is clearer.
3. Move declaration of |nsresult rv| into smaller scope as far as possible. This prevents setting rv to unexpected value and easier to check its value at reading the code.

This patch also renames:
EditorInputEventDispatcher -> mozilla::EditorInputEventDispatcher
And some variable names are renamed from aEditor or mEditor to aEditorBase or mEditorBase for making their types clearer.
