Currently, it takes a raw native message value, but it makes JS content too
complicated. And on Linux, it cannot synthesize non-primary button events
because GDK has only button press and release messages which dont' include
mouse button information.
For solving these problems, this patch creates a new abstract native message
as `nsIWidget::NativeMouseMessage` and makes each widget converts it to
a platform native message.
Additionally, this patch adds an argument to make it possible its callers
to specify pressing or releasing mouse button with a DOM mouse button value.
Note that the following patch adds new argument to
`synthesizeNativeEventMouse*` for mochitests and which will be tested by
new tests.

In most cases, `InputEvent.getTargetRange()` of `beforeinput` event should
return `Selection` ranges at dispatching the event.
This patch also handles special cases.
* composition change - target range should be the previous composition string
which will be replaced with new composition string.
* replace text - target range should be the replace range. This is used by
spellchecker.
* drop - target range should be the drop point.
However, the other exception is not handled by this patch. That is, deletions.
The target range(s) should be the range(s) which will be removed. In most
cases, they also matches selection ranges, but may be extended to:
* surrogate pair boundary
* grapheme cluster boundary like complex emoji
* word/line deletion deletion
* `Backspace` or `Delete` from collapsed selection
* to end of unnecessary whitespaces
For supporting these cases, we need to separate
`HTMLEditor::HandleDeleteSelection()` and its helper methods and helper class
to range computation part and modifying the DOM tree part. Of course, it
requires big changes and `InputEvent.getTargetRanges()` may be important for
feature detection of `beforeinput` event so that we should put off the big
changes to bug 1618457.

`GetInternalCommand()` is currently used only by `EditorCommand` and it
treats the additional parameter only when given command is `cmd_align`.
However, the value is complicated since `AlignCommand` allows both `CString`
value and `String` value. Therefore, `EditorCommand::DoCommandParams()` may
fail to solve `cmd_align` to a `Command` value without checking both of them.
Therefore, it must make sense that `GetInternalCommand()` take `nsCommandParams`
as optional argument and check it only when given command matches `cmd_align`.
Then, we don't need to waste unnecessary run-time cost.
Note that this bug has been hidden since `AlignCommand` class does not refer
the `Command` value but refers only `nsCommandParams`. However, the previous
patch makes `EditorCommand::GetParamType()` not allow `Command::DoNothing`.
Therefore, we need this follow-up fix now.

Most `EditorCommand` classes don't require additional params for executing
a command. All of them just calls their `DoCommand()` or returns same result.
So, we can create new virtual method,

which just delegates to `DoCommand()`.
This patch adds some undeclared commands but which are handled by

If user disables clipboard events, it means that they don't want to expose
clipboard data to web apps even if web apps cannot handle "paste" operation.
Therefore, they must not want to leak clipboard data with `InputEvent.data`
and `InputEvent.dataTransfer`.
This patch makes `InputEvent::GetData()` and `InputEvent::GetDataTransfer()`
returns empty string or new `DataTransfer` object which has only empty string
if:
- They are called by content JS.
- The event is a trusted event.
- `inputType` value is `insertFromPaste` or `insertFromPasteAsQuotation`.
The reason why we don't return null for both is, Input Events spec declares
`data` or `dataTransfer` shouldn't be null in the `inputType` values. And
the reason why we don't return empty `DataTransfer` is, web apps may expect
at least one data is stored in non-null `dataTransfer` value.

Although neither Chrome nor Safari does not set InputEvent.data when the event
is caused by `document.execCommand()` with `backColor`, `foreColor` nor

Safari sets it (*1).
Additionally, currently Safari uses `rgb()` to represents a color value and
using same rule to serializing color value for CSS OM matches Safari's behavior
and can represent any valid color values.
This patch makes given color value parsed and then serialized with same code

the value as-is for now. Additionally, when given value is invalid, sets the value
as-is for forward compatibility.

This patch implements InputType.inputType which is declared by Input Events.
The attribute has already been implemented by Chrome and Safari. Chrome
implements Input Events Level 1, but Safari implements Input Events Level 2.
Difference between them is only whether it supports "insertFromComposition",
"deleteByComposition" and "deleteCompositionText". This patch makes the
level switchable with pref and takes Level 1 by default because Level 2 is
still unstable around event order with composition events.
For reducing string copy cost at dispatching "input" event, this patch
makes EditorInternalInputEvent store valid input-type as enum class,
EditorInputType and resolves it to string value when
dom::InputEvent::GetInputType() is called. Note that the reason why
this patch names the enum class as EditorInputType is, there is InputType
enum class already for avoiding conflict the name, this appends "Editor"
prefix because "input" and "beforeinput" events are fired only when an
editor has focus.

Let's make TextInputHandler::HandleCommand() handle other
commands which are caused by Backspace, Delete, Tab, ArrowUp,
ArrowDown, ArrowRight, ArrowLeft, PageUp, PageDown, Home, End
and Escape keys with various modifiers.
This patch makes Korean users can do most key operation in
editor even with composing Hangul character.
Note that this patch has a hack for cancelOperation: command.
The command is typically fired for Escape key press. However,
it's also fired for Command + Period. Unfortunately, this
behavior is really odd if subclass of NSResponder implements
|void cancelOperation:(id)sender|. If it's implemented,
Cocoa doesn't call its |void keyDown:(NSEvent)theEvent|.
Instead, it calls only |void doCommandBySelector:(SEL)aSelector|
and |void cancelOperation:(id)sender| when Command + Period is
pressed. Therefore, we cannot dispatch keydown nor keypress
event for this key combination if we implement it. Therefore,
this patch doesn't implement the method but handle it in
doCommandBySelector even though the super class of ChildView
cannot handle the command with this path.

Currently, edit commands for native key bindings are stored in widget. This is
stateful and really complicated in content process because it needs to cache
them.
We can make this simpler if we make WidgetKeyboardEvent store edit commands for
the key combination. Then, child process can handle it even if it's delayed
event or it's a nested event.
This patch adds arrays to WidgetKeyboardEvent to store edit commands which are
initialized with nsIWidget::ExecuteNativeKeyBinding() and adds
WidgetKeyboardEvent::ExecuteEditCommands() to execute stored edit commands as
same as nsIWidget::ExecutenativeKeyBinding().

This patch implements some helper methods to log constants related to event handling.
ToString(KeyNameIndex) and ToString(CodeNameIndex) converts the enum itmes to human readable string. They use WidgetKeyboardEvent's helper class which returns Unicode text. Therefore, this need to convert from UTF16 to UTF8. That's the reason why these methods don't return |const char*|.
GetDOMKeyCodeName(uint32_t) returns DOM keycode name if it's defined. Otherwise, returns hexadecimal value. For generating switch-case statement, VirtualKeyCodeList.h shouldn't include ",". Therefore, this patch removes "," from VirtualKeyCodeList.h and append it at defining NS_DEFINE_VK. Additionally, the last item of enum and array should not end with ",". Therefore, this adds dummy last item at each of them. Finally, some of the keyCode values are shared between 2 keys. Therefore, it needs to support NS_DISALLOW_SAME_KEYCODE for switch-case generator. See the comment in the file for more detail.
GetModifiersName(Modifiers) returns all modifier names included in the given value.

PluginInstanceChild needs to send native key event to the chrome process via a content process. So, IPC needs a platform independent class/struct which can store native event. This purpose is exactly same as the purpose of WidgetGUIEvent::PluginEvent. Therefore, we can use it for this case too.
This patch renames WidgetGUIEvent::PluginEvent to NativeEventData but this patch does NOT remove WidgetGUIEvent::PluginEvent. Instead of that, it's defined as an alias of NativeEventData since PluginEvent is clearer name for the original purpose and it's used by plugin module.
