This is an extension protocol that can be used for platform specific
API (ie. AccessibleWrap methods).
I'm not thrilled with the seperate constructor for the sub-protocol.
This means that the parent won't have the actor upon DocAccessibleParent
construction, and some timing bugs can arise because of the extra round
trip. It would be cool if both actors could be co-created, but that
would require ManagedEndpoint, and for PBrowser to manage them both. I

Editor creates a `<br>` element when it's root element is empty.
Then, it's stored by `TextEditRules::mBogusNode` and used for checking
whether the editor is empty quickly. However, this `<br>` element has
`mozeditorbogusnode` attribute whose value is `true`. However, adding or
removing the attribute is not cheap and web apps can refer such illegal
attribute.
Therefore, this patch makes `HTMLBRElement` take a specific flag whether
it's a bogus node or not. However, this means that this hacky thing will be
exposed outside editor module. For making what is the bogus node clearer,
this patch calls the such `<br>` elements as "padding `<br>` element for
empty editor". So, this patch also includes a lot of renaming methods and

Normally, the OuterDocAccessible is created first and the DocAccessibleParent for a remote document is created after that.
So, we get the OuterDocAccessible and call DocAccessibleParent::SendParentCOMProxy when the DocAccessibleParent is constructed (BrowserParent::RecvPDocAccessibleConstructor).
However, sometimes, the OuterDocAccessible is created *after* the DocAccessibleParent.
This sometimes happens for extension popups, for example.
In that case, we previously never sent the parent COM proxy.
Aside from leaving the remote document with a null parent, this also meant we never sent any events for the document, since events are buffered for remote documents until the parent COM proxy is received.
This effectively left the remote document (e.g. extension popup) inaccessible.
Now, we also call SendParentCOMProxy in the OuterDocAccessible constructor.
Note that this doesn't result in duplicates because if the OuterDocAccessible was created first, there won't be a DocAccessibleParent for the remote document yet, so this code won't run.
That said, if the OuterDocAccessible is recreated (e.g. due to frame reconstruction), we may call SendParentCOMProxy again.
This should be okay, but it required an assertion in DocAccessibleChild::RecvParentCOMProxy to be tweaked.

Aside from the parent being needed by the client, this is also important because events from the embedded document are deferred until the parent COM proxy is received.
As part of this, we no longer try to send the parent COM proxy during construction of an OuterDocAccessible in the parent process.
This was previously a no-op anyway, as DocAccessibleParent::SendParentCOMProxy called DocAccessible::GetAccessible for the frame element, which would have returned null because the accessible isn't bound to the document until *after* it is constructed.
Changing this to directly pass the OuterDocAccessible was causing assertions in content processes, since it sometimes meant the parent COM proxy was sent twice, which is precisely what the assertion is protecting against.
Instead, the parent proxy is sent in Browserparent::RecvPDocAccessibleConstructor as it always was.

Sometimes, we use aria-activedescendant targeting something which isn't actually a descendant.
This is technically a spec violation, but it's a useful hack which makes certain things much easier.
For example, we use this for "fake focus" for multi select browser tabs and Quantumbar autocomplete suggestions.
This already worked previously; the accessible received a focus event and the focused state.
However, it did *not* receive the focusable state.
This is because the code which applies the focusable state for potential active descendants only works for descendants.
It really doesn't make sense for something to be focused when it isn't focusable.
In fact, this is an a11y test failure when it occurs.
So, if the active item has the focused state, ensure we expose the focusable state too.

There's a few subtle behavior changes here, which I'll try to break down in the
commit message.
The biggest one is the EditableDescendantCount stuff going away. This
was added in bug 1181130, to prevent clicking on the non-editable div from
selecting the editable div inside. This is problematic for multiple reasons:
* First, I don't think non-editable regions of an editable element should
be user-select: all.
* Second, it just doesn't work in Shadow DOM (the editable descendant count is
not kept up-to-date when not in the uncomposed doc), so nested
contenteditables behave differently inside vs. outside a Shadow Tree.
* Third, I think it's user hostile to just entirely disable selection if you
have a contenteditable descendant as a child of a user-select: all thing.
WebKit behaves like this patch in the following test-case (though not Blink):

Edge doesn't seem to support user-select: all at all (no pun intended).
But we don't allow to select anything at all which looks wrong.
* Fourth, it's not tested at all (which explains how we broke it in Shadow DOM
and not even notice...).
In any case I've verified that this doesn't regress the editor from that bug. If
this regresses anything we can fix it as outlined in the first bullet point
above, which should also make us more compatible with other UAs in that
test-case.
The other change is `all` not overriding everything else. So, something like:
<div style="-webkit-user-select: all">All <div style="-webkit-user-select: none">None</div></div>
Totally ignores the -webkit-user-select: none declaration in Firefox before this
change. This doesn't match any other UA nor the spec, and this patch aligns us
with WebKit / Blink.
This in turn makes us not need -moz-text anymore, whose only purpose was to
avoid this.
This also fixes a variety of bugs uncovered by the previous changes, like the
SetIgnoreUserModify(false) call in editor being completely useless, since
presShell->SetCaretEnabled ended in nsCaret::SetVisible, which overrode it.
This in turn uncovered even more bugs, from bugs in the caret painting code,
like not checking -moz-user-modify on the right frame if you're the last frame
of a line, to even funnier bits where before this patch you show the caret but
can't write at all...
In any case, the new setup I came up with is that when you're editing (the
selection is focused on an editable node) moving the caret forces it to end up
in an editable node, thus jumping over non-editable ones.
This has the nice effect of not completely disabling selection of
-moz-user-select: all elements that have editable descendants (which was a very
ad-hoc hack for bug 1181130, and somewhat broken per the above), and also
not needing the -moz-user-select: all for non-editable bits in contenteditable.css
at all.
This also fixes issues with br-skipping like not being able to insert content in
the following test-case:
<div contenteditable="true"><span contenteditable="false">xyz </span><br>editable</div>
If you start moving to the left from the second line, for example.
I think this yields way better behavior in all the relevant test-cases from bug
1181130 / bug 1109968 / bug 1132768, shouldn't cause any regression, and the
complexity is significantly reduced in some places.
There's still some other broken bits that this patch doesn't fix, but I'll file
follow-ups for those.

There's a few subtle behavior changes here, which I'll try to break down in the
commit message.
The biggest one is the EditableDescendantCount stuff going away. This
was added in bug 1181130, to prevent clicking on the non-editable div from
selecting the editable div inside. This is problematic for multiple reasons:
* First, I don't think non-editable regions of an editable element should
be user-select: all.
* Second, it just doesn't work in Shadow DOM (the editable descendant count is
not kept up-to-date when not in the uncomposed doc), so nested
contenteditables behave differently inside vs. outside a Shadow Tree.
* Third, I think it's user hostile to just entirely disable selection if you
have a contenteditable descendant as a child of a user-select: all thing.
WebKit behaves like this patch in the following test-case (though not Blink):

Sometimes, when cells have display:block, and a different cell in the same row has a column span, our index methods did not take these into account. Also, when regular tables encounter such a cell, index calculation failed.

This is preparation of the last patch. Even if no editor is clicked with
middle button, we need to do:
- collapse Selection at the clicked point.
- dispatch "paste" event.
Therefore, HandleMiddleClickPaste() should dispatch ePaste event by itself
and each editor methods should have a bool argument which the caller wants
ePaste event automatically.
Note that Chromium dispatches "paste" event and pastes clipboard content
into clicked editor even if preceding "auxclick" event is consumed.
However, our traditional behavior is not dispatching "paste" event nor
pasting clipboard content. Unless Chromium developer keeps their odd
behavior, we should keep our traditional behavior since our behavior is
conforming to DOM event model.

When dealing with an editor which contains multiple accessibles, the previous spelling error range might be in a previous accessible, not the accessible currently being queried.
In this case, DOMPointToOffset will return the length of this accessible.
Previously, we weren't checking for this and were overriding the start offset of the returned range regardless, resulting in broken offsets.
Now, we leave the start offset alone in this case.

User may paste a lot with pressing Accel+V for a while (i.e., with auto repeat).
So, calling nsIEditor::Paste() may be in a hot path and we can now make
non-virtual public method with AsHTMLEditor().

It's currently only accessible on XULDocument and XULElement, but that makes porting existing

this can be easily moved and exposed in chrome contexts.

nsIAccessibleText.setSelectionBounds should accept a start offset that is larger than an end offset. This is an indica tion that it is a reverse selection, and the caret should be at the start of the selection.
This should also be consistent with how multiple range selections work interactively - the caret should re
main at the last offset reached.

Using concrete class types with static IIDs in QueryInterface methods is a
pretty common pattern which isn't supported by any existing helper macros.
That's lead to separate ad-hoc implementations, with varying degrees of
dodginess, being scattered around the tree.
This patch adds a helper macro with a canonical (and safe) implementation, and
updates existing ad-hoc users to use it.

According to existing comments, TextEditor::TypedText() and
HTMLEditor::TypedText() are intentional bottleneck to debug. However, only
for that purpose, it and its internal methods are made virtual. This really
doesn't make sense.
So, this patch creates TextEditor::OnInputText() for callers of TypedText()
with non-empty string, TextEditor::OnInputParagraphSeparator() for callers
of TypedText() with eTypeBreak (Enter key or insertParagraphSeparator),
HTMLEditor::OnInputLineBreak() for callers of TypedText() with eTypeBR
(Shift + Enter or insertLineBreak). Additionally, this creates internal
non-virtual methods for XPCOM methods which are used as internal methods of
TypedText(). One is InsertTextAsAction() for nsIPlatintextEditor.insertText().
the other is InsertParagraphSeparator() for nsIPlaintextEditor.insertLineBreak().
Although those new methods are not have "WithTransaction" postfix, they must
be clearer they'll use transactions since user input and actions should be
undo-able.

First, EditorBase::DeleteSelection() is never used since
TextEditor::DeleteSelection() overrides it but does not call it. So, this patch
makes EditorBase::DeleteSelection() only returns NS_ERROR_NOT_IMPLEMENTED.
Next, EditorBase::DeleteSelectionImpl() actually removes content for
TextEditor::DeleteSelection(). So, it should be named as
DeleteSelectionWithTransaction(). However, it'll be done in the following
patch. On the other hand, its callers are EditorBase::HandleKeyPressEvent()
and EditorBase::DeleteSelectionAndPrepareToCreateNode(). Fortunately, they
can be moved to TextEditor simply. Therefore this patch moves the methods
to TextEditor for making related methods in a place.
Then, we can make the implementation of nsIEditor::TextEditor() as a non-virtual
method, TextEditor::DeleteSelectionAsAction().
