HTMLEditRules::MaybeSplitAncestorsForInsert() may be called with a point in a
text and it needs to return given split point as is. Additionally, the given
point may be in a text node. So, it may not be represented with an
nsCOMPtr<nsIContent>.
Therefore, we need to add new member, EditorDOMPoint, to SplitNodeResult and
when MaybeSplitAncestorsForInsert() needs to return the given point as is,
it should use it.
Note that if the methods which return SplitNodeResult split some nodes actually,
the left node and/or the right node may be removed from the DOM tree. In this
case, EditorDOMPoint cannot store such orphan node. Therefore, we cannot
make mNextNode nor mPreviousNode EditorDOMPoint.

Now, we can make HTMLEditRules::SplitAsNeeded() use |SplitNodeResult| as its
result and |const EditorRawDOMPoint&| as specifying start of the deepest right
node. Then, the implementation becomes simpler.
And I think that we should rename it to MaybeSplitAncestorsForInsert().
Additionally, this patch makes it stop calling
EditorBase::IsDescendantOfEditorRoot() and HTMLEditor::GetActiveEditingHost()
because they are really expensive. Instead, it should check if the given start
point of the deepest right node is in active editing host before the loop and
if the loop reaches editing host.

First of all, this patches fixes a bug of EditorBase::CreateNode(). It takes
|EditorRawDOMPoint&| but it should be |const EditorRawDOMPoint&| for making
callers can specify temporary instances.
Next, this patch creates |SplitNodeResult| stack class for result of
EditorBase::SplitNodeDeep(). SplitNodeDeep() needs to return previous node
and next node of split point. They are called as left node and right node,
but these calls are really different term usage. Therefore, this patch names:
aOutLeftNode -> SplitNodeResult::GetPreviousNode()
aOutRightNode -> SplitNodeResult::GetNextNode()
and also declares SplitNodeResult::GetLeftNode() and
SplitNodeResult::GetRightNode() which are same meaning as left/right node of
other splitting methods.
Additionally, of course, this patch makes SplitNodeDeep() use
|const EditorRawDOMPoint&| to receive the start point of right node.

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

We hit assertion which were added by bug 1414713. That tells us an ancient bug.
There is comment which claims that we should move all list items in the right
list node to left list node if the list nodes should be merged. However, this
has never been done actually since 2002. The code tried to move *some* list
items in the right list node to the list list node. However, retrieving first
list item at an offset almost always failed because the offset variable has
never been initialized.
If we believe the comment, we should move all children of the right list node
to the left list node. However, until we get a testcase to reach this case,
we should keep current behavior, i.e., do nothing, for unexpected regression.

libpref only allows pref modifications in the parent process. This patch
tightens up the checking, which is a bit inconsistent.
- It removes ENSURE_MAIN_PROCESS_WITH_WARNING, which does NS_WARNING on
failure, and replaces its uses with ENSURE_MAIN_PROCESS, which does NS_ERROR
on failure. This required adding an XRE_IsParentProcess() check to one place
in editor/.
- It converts XRE_IsContentProcess() tests to !XRE_IsParentProcess(), because
we now have multiple kinds of non-parent process.

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

RangeBoundaryBase shouldn't compute mRef when it's initialized with offset.
E.g., some users of the template class may initialize it with a container and
offset in it but it may not refer mRef or may refer after modifying offset.
On the other hand, RangeBoundaryBase::InvalidateOffset() is a special method.
It assumes that mRef is always initialized when it's called but can be
invalidate mOffset until retrieved actually. This is necessary for
nsRange::mStart and nsRange::mEnd since the offset may be changed when
some nodes are inserted before the referring node.
So, now, InvalidateOffset() should be a protected method and make nsRange a
friend class of RangeBoundaryBase. Then, when nsRange sets mStart and/or mEnd,
nsRange itself should guarantee that their mRefs are initialized.

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.

HTMLEditRules::BustUpInlinesAtRangeEndpoints() tries to split all inline nodes
at range start and range end. It uses EditorBase::SplitNodeDeep() to split
the nodes and HTMLEditRules::GetHighestInlineParent() to retrieve the highest
inline parent of them.
Currently, HTMLEditRules::GetHighestInlineParent() may return editing host or
ancestor of it if active editing host is not block. Then, it may cause
splitting editing host or its parents and following methods of HTMLEditRules
will fail to modify the nodes created outside the editing host.
So, HTMLEditRules::GetHighestInlineParent() should return only one of the
descendants of active editing host.
Unfortunately, even if just adding the test case as a crash test, I cannot
reproduce the crash with automated tests. Therefore, this patch doesn't
include any automated tests.
And this patch changes a crash test, 1402196.html, which expects that an inline
editing host is split by execCommand("insertOrderedList"). However, this patch
fixes this wrong behavior. Therefore, this patch changes the event target of
event listener from <p> inside the editing host to the editing host itself.
