Bug 1400459 devirtualized nsIAtom so that it is no longer a subclass of
nsISupports. This means that nsAtom is now a better name for it than nsIAtom.

This patch merges nsAtom into nsIAtom. For the moment, both names can be used
interchangeably due to a typedef. The patch also devirtualizes nsIAtom, by
making it not inherit from nsISupports, removing NS_DECL_NSIATOM, and dropping
the use of NS_IMETHOD_. It also removes nsIAtom's IIDs.
These changes trigger knock-on changes throughout the codebase, changing the
types of lots of things as follows.
- nsCOMPtr<nsIAtom> --> RefPtr<nsIAtom>
- nsCOMArray<nsIAtom> --> nsTArray<RefPtr<nsIAtom>>
- Count() --> Length()
- ObjectAt() --> ElementAt()
- AppendObject() --> AppendElement()
- RemoveObjectAt() --> RemoveElementAt()
- ns*Hashtable<nsISupportsHashKey, ...> -->
ns*Hashtable<nsRefPtrHashKey<nsIAtom>, ...>
- nsInterfaceHashtable<T, nsIAtom> --> nsRefPtrHashtable<T, nsIAtom>
- This requires adding a Get() method to nsRefPtrHashtable that it lacks but
nsInterfaceHashtable has.
- nsCOMPtr<nsIMutableArray> --> nsTArray<RefPtr<nsIAtom>>
- nsArrayBase::Create() --> nsTArray()
- GetLength() --> Length()
- do_QueryElementAt() --> operator[]
The patch also has some changes to Rust code that manipulates nsIAtom.

On macOS, we fall back eKeyPress event to native menu. Therefore, widget always requests a reply from remote process because it's difficult to check if the eKeyPress event will be sent to a remote process actually. If it's not sent to any remote processes, PresShell needs to dispatch the event into the DOM tree. Additionally, even if it's marked as "waiting reply from remote process", it needs to dispatch the DOM event in the main process first because we need to check if the key combination is reserved by chrome (if it's reserved, the eKeyPress event shouldn't be fired in the remote process).
Therefore, this patch makes EventStateManager::PreHandleEvent() resets the state when focused content isn't in any remote processes and the event's propagation hasn't been stopped.
Additionally, this patch makes PresShell::HandleEventInternal() checks WidgetEvent::PropgationStopped() with WidgetEvent::IsWaitingReplyFromRemoteProcess() before dispatching the event into the DOM tree.

nsMenuBarListener::KeyPress() is eKeyEvent listener in the system event group. If the target is a remote process, it shouldn't handle accesskey immediately because preceding eKeyDown event may be consumed in the remote process or eKeyPress event itself may be consumed in the remote process.
This patch makes nsMenuBarListener::KeyPress() mark eKeyPress event as "waiting reply from remote process" only when the event matches with a menu item's accesskey and it will be send to a remote process later. Then, reply event should be handled in this method if it's available.

Currently, access key is handled in EventStateManager::PreHandleEvent() with eKeyPress event, i.e., before dispatching it into the DOM tree, if the access key is registered in EventStateManager. So, the main process does not check if the preceding eKeyDown event is consumed in focused remote process.
When preceding eKeyDown event is consumed in the main process, eKeyPress event won't be dispatched by widget. However, if remote process has focus, it's impossible widget to stop dispatching eKeyPress event because preceding eKeyDown event hasn't been handled in the focused remote process yet. Therefore, main process needs to post eKeyPress event to check if preceding eKeyDown event was consumed. When eKeyPress event is marked as "waiting reply from remote process", TabChild sends it back to the main process only when preceding eKeyDown event wasn't consumed. So, only when eKeyPress event is back to the main process, main process should handle accesskey with it.
This patch makes EventStateManager::PreHandleEvent() check if a remote target has focus before handling accesskey. If a remote process has accesskey and there is an accesskey matching with eKeyPress event, it marks the event as "waiting reply from remote content" and stop propagation in the process.
Finally, when eKeyPress event is sent back to TabParent, TabParent::RecvReplyKeyEvent() calls EventStateManager::HandleAccessKey() before dispatching the reply event into the DOM tree.

Currently, it's not been managed yet that whether an event is posted to at least one remote process. So, for managing the state, BaseEventFlags should have a new bool flag and WidgetEvent and BaseEventFlags should have helper methods for it.
Additionally, this fixes a bug of nsGUIEventIPC.h. In a lot of ParamTraits, static_cast<Foo> is used for using base class's ParamTraits. However, it causes creating temporary instance with copy constructor. Therefore, WidgetEvent::MarkAsPostedToRemoteProcess() call in ParamTraits<mozilla::WidgetEvent>::Write() didn't work as expected.

Currently, we have 2 bool flags (and optional 2 bool flags with related purpose) for managing propagation state between parent process and remote process. However, it's really complicated. Actually, setting these flags and referring the flags is usually follow explanation.
So, for making simpler, WidgetEvent and BaseEventFlags should have some utility methods for making them as self documented code.
This patch moves WidgetKeyboardEvent::mIsReserved to BaseEventFlags::mIsReservedByChrome. That allows us to manage the cross process event propagation state in same place.

Focus can change at any moment in a document. This causes non-determinism and
correctness problems for doing keyboard apz scrolling. To get around this, we
will maintain deterministic behavior for focus changes initiated by input events
and see if we can get away with more non-determinism for things like `setTimeout`
In order to do this, we disable async keyboard scrolling when an input event is
processed that could have a event listener. We then attach a sequence number to
that input event and dispatch it to content. In content, we record the highest
sequence number that we have processed from an event, and send that on each focus
update. Using this, we can determine in APZ if we have a current focus target or
if we are still waiting for an input event to be processed and focus to be
reconfirmed.

Currently, EventListenerManager calls WidgetEvent::PreventDefault() when the status is nsEventStatus_eConsumeNoDefault. That causes unexpected state of events. So, WidgetEvent should do nothing when it's not cancelable but PreventDefault() is called.

It doesn't make sense to check this in a static method of EventStateManager.cpp. Instead, it should be a class method of WidgetEvent. Then, everybody can check this in everywhere.
This patch adds mFlags.mNoCrossProcessBoundaryForwarding because when it's true, any events shouldn't be sent to remote process.

After click events with button 2 or 3 are fired, fire auxclick, a new
event intended to represent a non-primary mouse click. Because this
event, based on the design examples and blink's implementation, is
intended to be used with content listeners, always dispatch on content
listeners--not just those that force all events to be dispatched (i.e.
document/window). This diverges from the behavior of our click events
from non-primary buttons.
Eventually, we hope this will replace click events for non-primary
buttons. For now, leave those events for compatibility reasons.
Additionally, add handling of this new event, where necessary.

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.

risen is the past participle of rise; raised is the past participle of
raise, which is what is done to exceptions.
See:
https://en.wiktionary.org/wiki/rise#Verbhttps://en.wiktionary.org/wiki/raise#Verb (definition 2, though not sure
if the use for exceptions is from 2.3 or 2.5)
(I wonder if mExceptionRaised would be simpler, though.)

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.

mDefaultPreventedByChrome is hacky. When PresShell handles Escape key events in fullscreen mode, it prevents default of every Escape key events and dispatch it only into chrome. After that, it check mDefaultPreventedByChrome if at least one call of preventDefault() occurred in chrome. Therefore, if we shouldn't set both mDefaultPreventedByChrome and mDefaultPreventedByContent to true before dispatching an event. This the reason why we need a special method, PreventDefaultBeforeDispatch() is needed for setting only mDefaultPrevented to true.
