WSRunObject::ConvertToNBSP() inserts an NBSP, then, removes following ASCII
whitespaces. When inserting an NBSP, mutation observer may change the
text node. In this case, it shouldn't keep working on removing ASCII
whitespaces because it may causes unexpected result.
This patch also renames ConvertToNBSP() and GetAsciiWSBounds() to
InsertNBSPAndRemoveFollowingASCIIWhitespaces() and
GetASCIIWhitespacesBounds() for making their jobs clearer.

Different from RangeBoundaryBase, EditorDOMPointBase can store only child node.
I.e., mOffset may be invalid until its Offset() is called. So,
GetChildAtOffset() isn't good name. It should be just GetChild().
Similarly, GetNextSiblingOfChildAtOffset() and
GetPreviousSiblingOfChildAtOffset() should be renamed to GetNextSiblingOfChild()
and GetPreviousSiblingOfChild().

EditorDOMPointBase::Container() may return nullptr. So, it should be renamed
to GetContainer().
Then, the method name becomes longer and a lot of callers access the result
directly. So, there should be following methods to make the callers shorter:
- GetContainerAsContent() to return the container as nsIContent*.
- GetContainerAsElement() to return the container as dom::Element*.
- GetContainerAsText() to return the container as dom::Text.
- GetContainerAsDOMNode() to return the container as nsIDOMNode*.
- CanContainerHaveChildren() to check if the container can have child nodes.
- IsInDataNode() to check if the point is in a data node including text node.
- IsInTextNode() to check if the point is in a text node.
- IsContainerHTMLElement() to check if the container is specific HTML element.
- IsContainerAnyOfHTMLElements() to check if the container is one of the
specified HTML elements.

The name, WSRunObject::CheckTrailingNBSP(), is unclear what it does. It
replaces previous character of specified point with ASCII space if it is NBSP
and it's not necessary.
So, it should be renamed to ReplacePreviousNBSPIfUnncessary().
Additionally, it should take |const EditorRawDOMPoint&| instead of a set of
container node and offset in it.

WSRunObject::GetChar(After|Before)(nsINode*, int32_t) returns next/previous
character's DOM point as WSPoint. If the container node is a text node in
mNodeArray, it calls WSRunObject::GetChar(After|Before)(const WSPoint&) which
returns next/previous offset if the point isn't end/start of the text node.
If the point is at end/start of the text node, it returns start/end of
next/previous text node in mNodeArray. If the container node is not a text
node in mNodeArray, it calls WSRunObject::GetWSPoint(After|Before)(). It looks
for next/previous text node in mNodeArray from the point. Then, it calls
WSRunObject::GetChar(After|Before)(const WSPoint&) and returns the result.
So, we should rename GetCharAfter() to GetNextCharPoint(), GetCharBefore() to
GetPreviousCharPoint(), GetWSPointAfter() to GetNextCharPointInternal() and
GetWSPointBefore() to GetPreviousCharPointInternal().
Then, they should take |const EditorRawDOMPoint&| instead of a set of container
node and offset in it.
So, looks like that "WS"RunObject is not good name for this class, perhaps,
AutoTextRunManager or something? But I'm still not sure.

WSRunObject::DeleteChars() should take two |const EditorRawDOMPoint&| arguments
to represent a range to remove.
Additionally, this renames it to DeleteRange() because it also removes any
nodes in the range. So, "Chars" isn't good word for this method's name.

WSRunObject::FindRun() finds the nearest run from aPoint to specified direction.
So, it uses nsContentUtils::ComparePoints() a lot. Therefore, it should use
an overload which takes RawRangeBoundary. Although, it's not optimized for
RawRangeBoundary, but if it'd be optimized, this method becomes faster.
And this patch renames it to FindNearestRun().

TextEditor::CreateBRImpl() should take |const EditorRawDOMPoint&| as insertion
point of new <br> element. Additionally, it doesn't need to have out argument
for the point of after <br> element because callers can get it with
EditorRawDOMPoint(nsINode*) and the new <br> node, and calling AdvanceOffset().
This cost must be enough cheap.

EditorBase::InsertTextImpl() takes |nsCOMPtr<nsINode>*|, |nsCOMPtr<nsIContent>*|
and |int32_t| as in/out arguments for container, child and offset of the child
in the container. But this makes the callers really hard to read and ugly.
So, we should make the method take |const EditorRawDOMPoint&| argument as input
and |EditorRawDOMPoint*| as out argument.

A lot of methods in editor returns a child offset with an out param when it
returns its container and offset in the container. This is ugly hack for
performance of nsINode::IndexOf(). However, there are a lot of regression
since the relation between offset and child node can be broken really easily.
So, we should make EditorDOMPoint as a subclass of RangeBoundary and manage
a set of container, reference child and its offset in it (e.g.,
SetNextSibling() added by this patch).
Note that RangeBoundary's performance is not good for temporary use if we set
a point with offset, it immediately retrieves mRef. The following patch will
improve this performance.

WSRunObject::InsertText() may delete given child node at offset with calling
DeleteChars() or CheckLeadingNBSP() before calling HTMLEditor::InsertTextImpl().
Therefore, even though using nsINode::GetChildAt() is slow, it needs to update
aInOutChildAtOffset after calling them.

After applying part 1 fix, it doesn't pass test_bug430392.html like the following..
1. content is <span contenteditable=false>A</span>[caret] ;
2. [VK_RETURN]
3. content is <span contenteditable=false>A</span><br>; <- whitespace is removed
Since we started to treat readonly text nodes as WSType::special with previous patch, WSRunObject::InsertBreak doesn't convert space (after caret) to NBSP because WSRunObject::InsertBreak does it only when inserted position isn't first text run object.
So even if this is first text run object, space after caret should be converted to NBSP.

This bug occurs that WSRunObject::PrepareToDeleteRangePriv() calls WSRunObject::ConvertToNBSP for non-editable text node.
Actually, even if text node isn't editable, WSFragment::mType becomes WSType::text now. So, whitespace only node at the end of contenteditable=false is treated as WSType::normalWS, i.e., treated as editable.
So text node in contenteditable=false should treated as WSType::special which means a non-editable inline object. Then, WSRunObject won't create object chunk of WSType::normalWS for text node in contenteditable=false.

nsRange::DoSetRange() adds/remove its root to/from mutation observer, initializes common ancestor, registers itself to the common ancestor, unregisters itself from old common ancestor, and notifies selection listeners of selection change.
However, those runtime cost is expensive but on the other hand, a lot of callers set both start and end of the range and that causes calling DoSetRange() twice.
This patch renames Set() to SetStartAndEnd() for easier to understand the meaning and make it call DoSetRange() only once.

Currently, when selection is collapsed at an empty text node, the behavior of each major browser is different.
When you remove the last character of non-empty text node followed by empty text nodes, Chromium removes all following empty text nodes. However, Edge never removes empty text nodes even when selection is collapsed at an empty text node.
With this patch, our behavior becomes same as Edge. I think that we should take this for keeping backward compatibility since Gecko never removes empty text nodes. So, in other words, this patch makes Backspace key press at an empty text node modify the preceding non-empty text node.
When you remove the first character of non-empty text node preceded with empty text nodes, Edge removes all preceding empty text nodes. However, Chromium and Gecko keeps previous empty text nodes than caret position. So, we should keep current behavior for backward compatibility. In other words, this patch makes Delete key press at an empty text node modify the following non-empty text node and keep current behavior.
The fixing approach of this is, making WSRunObject::PriorVisibleNode() and WSRunObject::NextVisibleNode() ignore empty text node. This should make sense because empty text node is not a visible node. (On the other hand, when the DOMPoint has a null character, it should treat as visible character. That is visible with Unicode codepoint.)

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.
