Deletion of mutation observers from a list resulted in O(n^2) behavior and could lead to massive freezes.
This is resolved by using a LinkedList instead, reducing complexity to O(n).
A safely iterable doubly linked list was implemented based on `mozilla::DoublyLinkedList`,
allowing to insert and remove elements while iterating the list.
Due to the nature of `mozilla::DoublyLinkedList`, every Mutation Observer now inherits `mozilla::DoublyLinkedListElement<T>`.
This implies that a Mutation Observer can only be part of one DoublyLinkedList.
This conflicts with some Mutation Observers, which are being added to multiple `nsINode`s.
To continue supporting this, new MutationObserver base classes `nsMultiMutationObserver` and `nsStubMultiMutationObserver` are introduced,
which create `MutationObserverWrapper` objects each time they are added to a `nsINode`.
The wrapper objects forward every call to the actual observer.

It's currently computes the corresponding editing host from the focus node of
`Selection` with climbing up the DOM tree. So, it does not just return a stored
element. Therefore, some callers use it multiple times. For avoiding it, we
should rename it to explain that it computes the editing host.
Note that I think that we should make it takes a node to compute editing host
without `Selection` for solving the case of no selection ranges. Therefore,
I don't like to include more information into the name.

This lifts a bunch of string conversions higher up the stack, but allows
us to make the servo code use utf-8 unconditionally, and seemed faster
in my benchmarking (see comment 0).
It should also make a bunch of attribute setters faster too (like
setting .cssText), now that we use UTF8String for them (we couldn't
because we couldn't specify different string types for the getter and
setters).

Although we use CSS property for Inline table editing UI, we use edit
transaction for it unfortunately. When hiding this UI, since removing
element doesn't use edit transaction, transaction will be canceled before
showing this UI.
It is unnecessary to use edit transaction for UI, so we shouldn't use it.

Due to the include hell, `EditorBase.h` cannot include `EditorUtils.h`.
Therefore we need these 3 methods once. Additionally, `IsModifiableNode()`
is really odd method and looks like that it's used for the following 2 purposes:
1. Simply can be editable.
2. Can be removed from parent.
For the former case, we should sort out it with
`EditorUtils::IsEditableContent()`, but for now, this patch moves it to
`HTMLEditUtils::IsSimplyEditable()`. On the other hand, for the latter case,
we obviously has a bug. Therefore, this patch creates
`HTMLEditUtils::IsRemovableFromParentNode()` and make it check whether the
removing node is also editable.
Unfortunately, `EditorUtils::IsEditableContent()` needs to take editor type.
But it's most callers are in `HTMLEditor` and most of remains are in
common methods of `EditorBase`. I guess we could remove this ugly argument
in the future.

BindContext was going to have way more information at first, but then I realized
that most of the things I wanted to know were basically a flag away using the

Still I think it's worth it, now experimenting with BindToTree will only mean
adding a field to a struct that's included from a couple cpp files, instead of a

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.
EditorBase::SelectionRefPtr() is now safe to use in editor and really fast to
retrieve Selection than EditorBase::GetSelection(). Therefore, we can get rid of
all Selection pointer/reference argument of each method which always take
normal Selection.
Note that this changes nsIHTMLEditor.checkSelectionStateForAnonymousButtons()
because its argument is only Selection. So, BlueGriffon should work even
though it calls the method with nsIEditor.selection.

First, nobody uses nsIHTMLObjectResizer.showResizers(). So, we can remove it.
Then, we have two private methods, one is non-virtual
HTMLEditor::ShowResizers(), and the other is HTMLEditor::ShowResizersInner().
HTMLEditor::ShowResizers() calls HTMLEditor::ShowResizersInner() and if
it fails, calls HideResizers(). However, in some cases, e.g., when it already
has visible resizers, hiding resizers does not make sense.
So, this patch removes non-virtual HTMLEditor::ShowResizers() method too,
then, renames HTMLEditor::ShowResizersInner() to HTMLEditor::ShowResizers(),
finally, it hides resizers only when it fails to setup resizers for keeping
resizers hidden.

HTMLEditor::RefereshEditingUI() works only with enabled UIs. Therefore, if
UI is disabled while it's visible, it keeps shown. This is too bad if web
apps tries to disable the Gecko specific UIs after we show some of them.
This patch adds HTMLEditor::HideAnonymousEditingUIsIfUnnecessary() to hide
unnecessary UIs and makes RefereshEditingUI() call it always.
First, HTMLEditor::HideInlineTableEditingUI() always returns NS_OK. So, we
can change its return type to void.
Additionally, it removes each UI from the DOM tree one by one. However, each
mutation could cause showing same UI again. In such case,
ShowInlineTableEditingUI() overwrites each UI with newly created element.
Then, HTMLEditor cannot remove the old UI anymore. Therefore, this patch
moves all members of the UI into local variables first.
HTMLEditor::CheckSelectionStateForAnonymousButtons() is called a lot internally.
Especially, its virtual call cost may make damage to our performance since
it's called from a selection listener.
So, we should create non-virtual method, RefereshEditingUI() for internal use.
We have another built-in UI of editor which is not implemented by any other
browsers. That is a draggable handler to move absolute positioned elements.
So, we should disable it in default for compatibility with the other browsers.
However, different from resizers and inline table editor, we don't have
command to enable/disable this feature but for backward compatibility, we
should have it. Therefore, this patch adds new command
"enableAbsolutePositionEditor".
Note that whether resizing UI is available only with enableObjectResizing
state is different from enableInlineTableEditing command. Resizers for
absolute positioned elements are NOT available both enableObjectResizing
and enableAbsolutePositionEditor are enabled.
Additionally, this adds automated tests to check basic functions of absolute
positioned editor.

Gecko supports resizers of <img> elements and <table>, <td>, <th> elements and
has UI to remove existing table row or column in default. However, the other
browsers don't have such UI and web apps need to disable this feature with
calling both:
document.execCommand("enableObjectResizing", false, false);
document.execCommand("enableInlineTableEditing", false, false);
for avoiding conflicting with their own features to edit such elements.
Therefore, it doesn't make sense to keep enabling them in default only on
Gecko. If web apps want to keep using these features, they should call:
document.execCommand("enableObjectResizing", false, true);
document.execCommand("enableInlineTableEditing", false, true);
at initializing the editor.
And also this patch fixes bugs of
document.queryCommandState("enableObjectResizing") and
document.queryCommandState("enableInlineTableEditing"). They always return
false even after calling document.execCommand(..., false, true) since
nsSetDocumentStateCommand::GetCommandStateParams() sets bool value as
STATE_ATTRIBUTE. However, nsHTMLDocument::QueryCommandValue() which is the
caller referring STATE_ATTRIBUTE doesn't treat it as bool value. And also
those commands are related to state of document. Therefore, they should be
return as bool value of STATE_ALL instead. Then,
nsHTMLDocument::QueryCommandState() returns the state as expected. Note that
those commands are supported only by Gecko. So, we don't need to worry about
the compatibility.
Finally, this patch rewrites 2 existing tests to check basic behavior of
resizers and appearance of resizers.
Note that this patch does not add new tests to test inline table editor
since it's difficult to test the behavior with current API. Perhaps, we
should add an API to nsIHTMLEditor to retrieve each anonymous elements in
another bug since it requires to add wrapping API of SpecialPowers.
