Current `nsIHTMLEditor::GetSelectedElement()` just checks whether the
found element is followed by `<br>` element or not. However, following
element may start with `<br>` element and if there is end of the range,
`PostContentIterator` does not list up the `<br>` element.
Therefore, it should check whether the found element is followed by
`<br>` element which is starts the next sibling element too.

In C++ code, `DataTransfer::GetTypes()` are used for checking whether the
`DataTransfer` instance has specific type `DataTransferItem` or not. Therefore,
it does not make sense to retrieve all item types nor compare some types
looking for with the retrieved item types.
This patch adds `DataTransfer::HasType()` and `DataTransfer::HasFile()` for
the current C++ users. They don't take `CallerType` since all C++ users use
`GetTypes()` as `CallertType::System`. And they just call a corresponding
method of `DataTransferItemList`.
Then, `DataTransferItemList` methods compares given type with every items
simply.
Note that this patch moves `DataTransfer::GetTypes()` to `DataTransferItemList`
too because new methods and `GetTypes()` should be maintained at every logic
changes.
The reason why there is no `DataTransfer::HasAnyOfTypes()` method is,
`DataTransfer.h` cannot include `DataTransferItemList.h` due to their
dependency but parameter pack requires inline methods.

When file is dropped on `contenteditable` element, the data is `BlobImpl`
instance in e10s mode. Then, editor tries to insert asynchronously with its
`BlobReader`. However, currently, `BlobReader` does not have a reference of
`DataTransfer` object for setting `beforeinput` event and `input` event.
Therefore, when you drop file into `contenteditable` element on debug build,
you see hitting `MOZ_ASSERT` because of unexpected null `DataTransfer` object.
This patch makes it store `DataTransfer` object for both `beforeinput` event
and `input` event, and dispatch `beforeinput` event only when it hasn't been
dispatched yet (i.e., not dispatched before it's created). The case shouldn't
occur, but let's have the fallback path in release builds for avoiding
inconvenience of our users.

It removes a script blocker. Therefore, although it depends on the caller
whether it causes running script or not. However, we should mark it as
`MOZ_CAN_RUN_SCRIPT` for safer code.
It's called only by the destructor of `nsAutoCauseReflowNotifier`. Therefore,
this patch also marks its constructor as `MOZ_CAN_RUN_SCRIPT` for making
each creator method marked as `MOZ_CAN_RUN_SCRIPT` or
`MOZ_CAN_RUN_SCRIPT_BOUNDARY`.
Most of the creators is mutation listener methods. However, `PresShell`
does nothing after destroying `nsAutoCauseReflowNotifier`. Therefore,
this patch does not change the callers in MutationObserver.cpp to use
`RefPtr<PresShell>` at calling them because changing it may cause performance
regression.
Perhaps, we should create another methods of `WillCauseReflow()` and
`DidCauseReflow()` to avoid unnecessary `MOZ_CAN_RUN_SCRIPT` marking.
However, I'm not sure whether most callers may run script or not because
of outside of my knowledge.

`UIEvent::GetRangeParent()` retrieves `nsIContent` instance but it needs to
return `already_AddRefed<nsINode>` because of a WebIDL method. However,
`nsIContent` is better type in C++ code. Therefore, this patch renames it
to `UIEvent::GetRangeParentContent()` and makes new `UIEvent::GetRangeParent()`
and just call it.
Additionally, some callers call `UIEvent::RangeOffset()` too, but that means
that they compute same things twice because both of them use
`nsLayoutUtils::GetContainerAndOffsetAtEvent()` with same input arguments.
Thus, `UIEvent::GetRangeParentContent()` should also return offset with optional
out argument. (Note that this does not make `RangeOffset()` use
`GetRangeParentContent()` because using out parameter for range parent causes
unnecessary computation cost for `RangeOffset()`.)
Therefore, finally, `UIEvent::GetRangeParentContent()` becomes also an alias of
raw method `UIEvent::GetRangeParentContentAndOffset()` which also returns offset
with out argument.

`AutoEditActionDataSetter` is created in the stack when editor's public method
is called and that guarantees lifetime of global objects in editor such as
editor itself, selection controller, etc.
The dispatcher of `beforeinput` event returns `NS_ERROR_EDITOR_ACTION_CANCELED`
if an event is actually dispatched but canceled. The reason why it's an error
is, editor code must stop handling anything when any methods return error.
So, returning an error code is reasonable in editor module. But when it's
filtered by `EditorBase::ToGenericNSResult()` at return statement of public
methods, it's converted to `NS_SUCCESS_DOM_NO_OPERATION`. This avoids throwing
new exception, but editor class users in C++ can distinguish whether each edit
action is canceled or handled. The reason why we should not throw new
exception from XPCOM API is, without taking care of each caller may break some
our UI (especially for avoiding to break comm-central). Therefore, this patch
does not make XPCOM methods return error code when `beforeinput` event is
canceled.
In most cases, immediately after creating `AutoEditActionDataSetter` is good
timing to dispatch `beforeinput` event since editor has not touched the DOM
yet. If `beforeinput` requires `data` or `dataTransfer`, methods need to
dispatch `beforeinput` event after that. Alhtough this is not a good thing
from point of view of consistency of the code. However, I have no better
idea.
Note 1: Our implementation does NOT conform to the spec about event order
between `keypress` and `beforeinput` (dispatching `beforeinput` event after
`keypress` event). However, we follow all other browsers' behavior so that it
must be safe and the spec should be updated for backward compatibility.

Note 2: Our implementation does NOT conform to the spec about event order

composition string in editor has not been modified yet. Therefore, this
may not cause web-compat issues (and I hope so).

Some HTML editor command classes call `*AsAction()` methods multiple times.
That causes that user needs multiple undo/redo for a command and one command
causes multiple "input" events. For both compatibility with the other
browsers and making "beforeinput" cancelable, they should call `*AsAction()`
once. Instead, `HTMLEditor` should handle related element deletion.
This patch makes `HTMLEditor::RemoveInlinePropertyInternal()` remove multiple
elements if its caller allows, and `HTMLEditor::SetInlinePropertyAsAction()`
call `RemoveInlinePropertyInternal()` in some cases.
According to comm-central and BlueGriffon, we can make
`HTMLEditor::RemoveInlineProperty()` also removes the related methods
automatically because comm-central does same thing from script and BlueGriffon
does not use this. However, we cannot do that for
`HTMLEditor::SetInlineProperty()` because BlueGriffon may call it with any
HTML5 elements and does not expect removing elements in same block at that

only `RemoveInlineProperty()`, but it would make these APIs behavior

Chrome moves focus to dropped element or editing host containing dropped
element, but we don't do it. For compatibility with Chrome, it's better to
follow their behavior. Additionally, this fixes 2 issues. One is, when
dropping something into non-focused contenteditable element, we've failed to
initialize selection from `TextEditor::PrepareToInsertContent()` because
`pointToInsert` is outside of selection limiter if another editing host
has focus. The other is, when same case, we've failed to insert dropped
content because edit action handlers of `HTMLEditor` check whether editing
position is in active editing host.
Finally, this patch makes `TextEditor::OnDrop()` cancels to dispatch "input"
event if it fails something before trying to insert dropped content. Without
this change, `EditorBase::DispatchInputEvent()` tries to dispatch without
proper `data` or `dataTransfer` and that hits `MOZ_ASSERT` in `nsContentUtils`.
Additionally, this fixes an existing bug which `HTMLEditor` may insert `\r`
as-is if it comes from paste or drop. Otherwise, we need complicated `todo_is`

the editor cannot remove the source element (e.g., outside of any editing host).
The drop effect is initialized by `nsContentUtils::SetDataTransferInEvent()`
which is called when `EditorEventListener::CanDrop()` and it returns true.
However, it requires unnecessary cost if we make `nsContentUtils` check
