We haven't logged KeymapWrapper::HandleKeyPressEvent() nor
KeymapWrapper::HandleKeyReleaseEvent(). Therefore, this patch makes them
put their behavior into the log.
Additionally, KeymapWrapper::InitKeyEvent() does not log enough the result
of initialized WidgetkeyboardEvent. This patch makes it log more.
With those changes, we can get the log of:
- detail of dispatched keyboard events
- which key event didn't cause keyboard events
- which keyboard event was consumed
Note that the utility methods are copied from widget/windows. Perhaps,
we should create XP logging helper for keyboard/IME later.

Some unusual keyboard layout may map a function key only with some
modifiers. For example, Hatchak keyboard layout maps Tab key to
"Digit3" key and Backspace key to Level3 Shift+"Digit3" key. So,
when Level3 Shift is active, the modifier state of the "Digit3" key
event shouldn't be ignored because computed keyCode value becomes
DOM_VK_TAB (9) rather than DOM_VK_BACK_SPACE (8).
This patch makes KeymapWrapper::ComputeDOMKeyCode() compute keyCode
value of non-printable key event with its modifier state first. If
it cannot map to a DOM keyCode value, then, it keeps ignoring the
modifier state for backward compatibility and making web apps be able
to identify the key as far as possible.
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.

Summary: Really sorry for the size of the patch. It's mostly automatic
s/nsIDocument/Document/ but I had to fix up in a bunch of places manually to
add the right namespacing and such.
Overall it's not a very interesting patch I think.
nsDocument.cpp turns into Document.cpp, nsIDocument.h into Document.h and
nsIDocumentInlines.h into DocumentInlines.h.
I also changed a bunch of nsCOMPtr usage to RefPtr, but not all of it.
While fixing up some of the bits I also removed some unneeded OwnerDoc() null
checks and such, but I didn't do anything riskier than that.
With an event filter method, we're logging all key events on any widgets to
check whether a key is pressed or not, to set
WidgetKeyboardEvent::mIsRepeat properly. If iBus and Fcitx work as expected,
they synthesize key events with setting their own modifier state which indicate
the events are synthesized by IME. In this expected case, synthesized key
events are not caught by the filter.
On the other hand, in some environment, they keep handling key events
asynchronously but they or something another module synthesizes key events
without the flag and such events are caught by the filter because the events
are posted into the event queue. Therefore, we decide that such synthesized
events are always generated by auto-repeat (first events which are always
filtered by IME are treated as first press, and then, synthesized events are
treated as repeated events because of no key release events).
This patch makes KeymapWrapper::FilterEvents() ignore coming KeyPress
events if:
- the time is exactly same as previous KeyPress event
- and IMContextWrapper instance is now waiting a GDK_KEY_PRESS event
- and hardware_keycode of waiting GDK_KEY_PRESS event is same as
keyCode of the KeyPress event

According to the log of bug 1498823, ibus won't set IBUS_IGNORED_MASK to
modifier flags when it synthesizes the event for asynchronous handling in
some environments.
Currently, we assume that iBus and Fcitx set IBUS_IGNORED_MASK or
FcitxKeyState_IgnoredMask. So, we put both real key events and synthesized
key events into the posting event queue and that causes using a lot of
memory until the editor is blurred. Fortunately, timestamp of synthesized
key events are always same as their original events. Therefore, we can look
for original event from the positing event queue.
Although we have gotten no bug reports about this issue of Fcitx, but this
patch adds same hack for Fcitx too because the runtime cost is not
expensive but the symptom is really serious.

The VisualViewport events are all nice and shiny, but unfortunately not quite
what is needed for the session store.
Firstly, the spec wants the "scroll" event to be fired only when the *relative*
offset between visual and layout viewport changes. The session store however
records the absolute offset and as such is interested in when *that* changes.
Secondly, again as per the spec the events don't bubble, and with the default
DOMEventTargetHelper implementation they don't escape the VisualViewport during
capturing, either. This means that any event listener must be added directly on
the VisualViewport itself in order to capture any events.
This might have been intended because the events use the same names as the
normal "scroll"/"resize" events, and as such you cannot specify separate event
listeners for VisualViewport and non-VisualViewport "scroll" events if both
events end up being dispatched to the same element (you can only try to filter
after the fact by looking at the originalTarget of the event).
At the same time, the VisualViewport is attached to the inner Window, and so
each time you navigate, you also get a different VisualViewport object.
All of this might be totally fine from the perspective of a page script, because
in that case you won't care anyway about what happens when the current page goes
away.
From the session store perspective on the other hand (especially Fennec's non-
e10s session store design), this is rather unfortunate because we don't want to
have to keep registering event listeners
a) manually for each subframe
b) each time the page navigates
The event target chain problem could be solved by letting the scroll events
escape the VisualViewport during the capturing phase (which the spec doesn't say
anything about), but this would mean that any scroll listener attached to a
window/browser/... that uses capturing will now catch both layout and visual
viewport scroll events.
In some cases this might even be beneficial, but in others (e.g. bug 1498812
comment 21) I'd like to specifically decide which kind of scroll event to
capture. Having to look at event.originalTarget to distinguish the two kinds
might be defensible in test code, but in case this distinction would be needed
in production code as well, given the existence of a C++-based filtering helper
in nsSessionStoreUtils for another use case where (scroll) events need to be
filtered, JS-based scroll event filtering might be a bad idea.
Additionally, in any case this wouldn't solve the fundamental conflict between
the spec and the session store about *when* the "scroll" event should be fired
in the first place.
Hence I'd like to introduce a separate set of events with distinct event names,
which will be dispatched according to the requirements of our internal users
(i.e. currently the session store). To avoid potential web compatibility issues
down the road, for now these events will be dispatched only to event listeners
registered in the system group (allowing *all* Chrome event listeners cannot be
done because checking the Chrome status of each event target might be too
expensive for frequently dispatched events).

The semantics of the VisualViewport resize/scroll events aren't quite what is
needed for internal browser usage, so we need a separate set of events that can
be used e.g. by the session store. To avoid future web compatibility issues,
that event should be kept internal, however none of the existing
options to achieve that are suitable:
- mNoContentDispatch can actually end up being dispatched to content after all
and as per its comment preferably shouldn't be used any more for new features
- mOnlySystemGroupDispatchInContent would work perfectly, except that it
shouldn't be used for frequent events, which the resize/scroll events
arguably are
- mOnlyChromeDispatch doesn't work for the Desktop session store's content
script, plus it might have the same performance problems as
mOnlySystemGroupDispatchInContent
Therefore, I propose to introduce a new mOnlySystemGroupDispatch event flag,
which skips the comparatively expensive IsCurrentTargetChrome() check and relies
only on the event listener having been registered in the system group.

To avoid FlushIMEChanges per updating IME composition, we calculate composition count in DoReplaceText. But when using GV+e10s, this calculation is sometimes invalid since NOTIFY_IME_OF_COMPOSITION_EVENT_HANDLED event isn't received per PendingComposition. Because, IMEStateManager will merge this completed events due to optimization of IME event.
Also, DoUpdateComposition calls SetPendingComposition, but it doesn't touch mIMEActiveCompositionCount,
So when using some IME, this value is minus or forever non-zero on some IMEs.
So we shouldn't use atomic count. When receiving NOTIFY_IME_OF_COMPOSITION_EVENT_HANDLED, we should reset it and allow IMEFlushChanges since Gecko has already handled all IME composition events in event queues.

IMMHandler and TSFTextStore are good class to put native caret when they have
enough information. However, for example, IMMHandler may not have its singleton
instance until first composition of IMM-IME starts. Therefore, typically,
IMEHandler is a good class to put native caret without composition.
This patch adds IMEHandler::MaybeCreateNativeCaret(), and if it won't create
native caret because not yet received WM_GETOBJCT for OBJID_CARET, we should
fire window event for MSAA applications. If there is new MSAA application
retrieves OBJID_CARET, we'll receive WM_GETOBJECT for OBJID_CARET
asynchronously. Then, we should start to put native caret for such
applications.
Note that if we create native caret, some versions of ATOK refers the native
caret and the behavior becomes worse than usual. Therefore, we need to
keep not using native caret as far as possible.

If WM_GETOBJECT for OBJID_CARET is received but a11y module is not active,
IME module should create native caret over our caret because Windows will
handle the request with native caret automatically and we don't need to
enable a11y module only for it.
This patch makes IMEHandler store whether such message has been received and
makes TSFTextStore create native caret when composition, selection or layout
is changed because especially when there is composition, only TSFTextStore
knows correct position to put caret if there is composition or some dispatched
events have not been handled by content process yet.
Note that IMMHandler already does that since some legacy IMEs require native
caret to show its UI and we cannot check active IME strictly. Therefore, this
patch does not touch IMMHandler.

IMEHandler needs to create native caret later (when there is no composition).
Therefore, IMEHandler should manage whether it creates native caret or not
and IMMHandler and TSFTextStore should create/destroy native caret via
IMEHandler.
Note that this patch makes IMMHandler stops managing whether native caret
is created for plugin or not because native caret is created only one instance
and anyway IME handlers should stop managing native caret when they loses
focus.

If a11y module is active, it observers caret position and size, and when caret
position or size is changed, it creates/moves native caret to overlap with
our caret.
On the other hand, IME module also creates native caret if active IME requires
it. Therefore, both of them conflicts each other.
This patch makes IME module stop touching native caret if a11y module is active.
Although, a11y module with Flush Player does not work well for IME. Therefore,
this patch keeps the conflict between them as-is for now.

If TSFTextStore fails to get selection, e.g., the content is really odd like
fuzzing tests, its mSelectionForTSF is marked as dirty. However, Windows may
try to retrieve writing mode while we're creating new TSFTextStore. Then, we
may hit MOZ_ASSERT(!mDirty) in TSFTextStore::Selection::GetWritingMode() in

So, we need to make some callers of GetWritingMode() check whether selection
