Masayuki Nakano 90cd469f14 Bug 1550462 - part 2: Make PresShell::HandleEvent dispatch preceding pointerrawupdate event r=smaug,dom-core,edgar 
This patch tries to dispatch ePointerRawUpdate with
PresShell::EventHandler::DispatchPrecedingPointerEvent as same as usual
pointer events.

For using the path, this patch adds 2 internal events, eMouseRawUpdate
and eTouchRawUpdate which are never dispatched into the DOM because
PresShell::EventHandler::DispatchPrecedingPointerEvent will return false
for that and then the caller will stop handling the internal events.

There are 3 dispatchers of the internal raw update events.

One is PresShell::EnsurePrecedingPointerRawUpdate(). This dispatches the
internal event if and only if the coming event of PresShell::HandleEvent will
cause ePointerMove. The reason why PresShell::HandleEvent handles the
preceding raw-update event is, we should support ePointerRawUpdate events
for synthesized events for tests (in-process ones) and in the main process.
Additionally, if a pointerrawupdate event may destroy the target <iframe>.
In such ase, the following pointermove may need to be dispatched on its parent
window or another <iframe> window. Therefore, we need to dispatch the
internal raw update event before considering the target window (PresShell) and
handling the capturing element.

The others are BrowserChild::RecvRealMouseMoveEvent and
BrowserChild::RecvRealTouchMoveEvent. They dispatch the internal events
when they won't dispatch the received event immediately to coalesce with further
similar input.

For avoiding to dispatch the internal event for same source event, this adds
WidgetPointerHelper::convertToPointerRawUpdate member to check it in
PresShell::HandlePrecedingPointerRawUpdate.

/**
* This header file lists up all event messages.
* Before including this header file, you should define:
* NS_EVENT_MESSAGE(aMessage)
*
* Additionally, you can specify following macro for e*First and e*Last.
* NS_EVENT_MESSAGE_FIRST_LAST(aMessage, aFirst, aLast)
* This is optional, if you need only actual event messages, you don't need
* to define this macro.
*
* Naming rules of the event messages:
* 0. Starting with "e" prefix and use camelcase.
* 1. Basically, use same name as the DOM name which is fired at dispatching
* the event.
* 2. If the event message name becomes too generic, e.g., "eInvalid", that may
* conflict with another enum's item name, append something after the "e"
* prefix, e.g., "eFormInvalid".
*
* NOTE: What you need to do when you add new event messages?
* - If the new events are dispatched to the DOM, they should be registered in
* dom/events/EventNameList.h
* - If the new events are dispatched to the DOM, set proper default values of
* "bubbles" and "cancelable" in WidgetEvent::SetDefaultCancelableAndBubbles()
* defined in widget/BasicEvents.h.
* - If the new events should be included into an existing event group, you may
* need to update WidgetEvent::Has*EventMessage() etc defined in
* widget/WidgetEventImpl.cpp.
* - If the new events are pointer event messages, update
* IsPointerEventMessage*() defined in widget/WidgetEventImpl.cpp.
* - Check whether the trusted events of the new messages are targeted to
* expected EventTarget by WidgetEvent::IsTargeted*(),
* WidgetEvent::IsUsingCoordinates(),
* WidgetEvent::IsAllowedToDispatchDOMEvent(),
* WidgetEvent::CanBeSentToRemoteProcess() etc which are defined in
* widget/WidgetEventImpl.cpp
* - If trusted events of the new events may be a content node but are allowed
* to fired only on an Element node, you need to update
* IsForbiddenDispatchingToNonElementContent() defined in
* widget/WidgetEventImpl.cpp.
* - Possibly handle them in PresShell::EventHandler,
* EventStateManager::PreHandleEvent and/or
* EventStateManager::PostHandleEvent.
