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.
