VSync on Wayland is a bit tricky as we can get only "last VSync" event signal with
CLOCK_MONOTONIC timestamp or none (if application is hidden/minimized).
That means we should draw a next frame at "last Vsync + frame delay" time and also
approximate next VSync event when we don't get any.

Currently, if an event is consumed in the main process, EventStateManager
does not send it to remote process. However, this is unexpected behavior
for some WidgetKeyboardEvent dispatchers. OS sometimes has consumed native
key events before sending applications. For example, Alt key on Windows
should activate menu bar of focused window but Alt key may be consumed before
focused window receives the event. In such case, we mark Alt keyboard event
as "consumed before dispatch", and chrome treat it like as its preventDefault()
is called in web content. (Note that for compatibility with other browsers,
the consumed state is not exposed to web content. So, Event.defaultPrevented
returns false in web content.)
Therefore, we need to treat "consumed" state and "cross process forwarding"
state separately. This patch makes calling WidgetEvent::PreventDefault()
always stops cross process forwarding for backward compatibility. Additionally,
for the special case mentioned above, this patch makes
WidgetEvent::PreventDefaultBeforeDispatch() take additional argument,
|aIfStopCrossProcessForwarding|. If this is CrossProcessForwarding::eStop,
the event won't be sent to remote process as same as calling PreventDefault().
Otherwise, CrossProcessForwarding::eHold, PreventDefaultBeforeDispatch() call
does not change "cross process forwarding" state. I.e., if the event's
StopCrossProcessForwarding() and PreventDefault() are not called until
EventStateManager::PostHandleEvent(), the event will be sent to remote process
as usual.

Different from Windows and macOS, we cannot check if active keyboard layout
works as "IME" actually. Therefore, this patch add the telemetry probe
to the dispatcher of eCompositionStart. However, composition string is also
used by some Wester keyboard layouts which have dead keys. So, the meaning
of the result is deferent from the other platforms, but it must be useful
information which IM (e.g., fcitx, ibus) is used by most users.

This patch adds a telemetry probe to collect Input Source ID or Bundle ID of
IME when an IME open mode is selected by user. Input Source ID includes
input mode of IME, but Bundle ID does not so. In most languages, we need
to collect the former, but only for Japanese IME, we need to collect the
latter because non-Japanese IME's input mode is "how to input characters".
So, the input mode is important. However, Japanese IME's input mode is
"to input which type of characters". So, Japanese IME user may use multiple
input modes but we need only the IME mode. If we'd collect number of
each input mode users of Japanese language, it'd be difficult to count
how many users actually used typical Japanese IME since somebody may use
only a mode, some others may use only different modes.
So, this patch collects Input Source ID when non-Japanese IME is open and
Bundle ID when Japanese IME is open.

We always struggle with a lot of IME bugs on Windows. Currently, any IME
vendors should've already released TIP for TSF rather than legacy IMM-IME
since IMM-IME is not available on UWP apps. Additionally, due to API
limitation, it's difficult to get human-friendly name of IMM-IME. So, let's
collect only TIP names of TSF on Windows. This must be enough.
Note that we cannot get common-English name even though the API to retrieve
TIP name taking language code. Therefore, a TIP may be collected with
different name, e.g., one is Japanese name and the other is English name.
If we collect GUIDs of TIP, we can avoid this issue. However, it's
difficult to collect both GUID and human-friendly name since Telemetry
key is up to 72 characters.
Currently, I give up to avoid this duplicated issue. Perhaps, this is not
so serious issue since most TIP users must match language of TIP and their
system language settings. Therefore, this patch collects Locale ID of
TIP and description of it. Locale ID is necessary because some TIPs may be
named same name for different languages. For example, both Japanese and
Hangul IMEs of Microsoft are named as "Microsoft IME".

Summary:
document.addEventListener("shadowrootattached", e => {
// Do stuff with composedTarget.
});
I didn't bother to add tests for the event itself since this is going to get
tested in bug 1449333, but I can look into writing a chrome mochitest if you
want.
Test Plan: See above.

This patch is an automatic replacement of s/NS_NOTREACHED/MOZ_ASSERT_UNREACHABLE/. Reindenting long lines and whitespace fixups follow in patch 6b.

I'm replacing non-failing calls to NS_NOTREACHED with MOZ_ASSERT_UNREACHABLE, but this NS_NOTREACHED fails when running the browser/base/content/test/general/browser_tab_dragdrop2.js test because mContainer is unexpectedly *not* null. This is bug 1469183.
This patch DOES NOT fix the cause of the assertion failure. It just replaces this failing NS_NOTREACHED with NS_ERROR because I can't replace with a fatal MOZ_ASSERT_UNREACHABLE.

|name| is too generic but the scope is too wide in test_keycodes.xul.
So, let's rename it to |currentTestName|.

When AltGr key is pressed, following messages come:
1. WM_KEYDOWN for ControlLeft
2. WM_KEYDOWN for AltLeft
3. WM_SYSKEYUP for ControlLeft
4. WM_KEYUP for AltLeft
In these key sequence, KeyboardEvent.key value of keydown event at #2 and keyup
event at #4 should be "AltGraph". This patch fixes the key value and
adding new test into test_keycodes.xul to check the behavior with
SynthesizeNativeKey().

Users can emulate AltGr key with pressing both Ctrl key and Alt key on Windows
since AltGr is represented as so in Windows and physical keyboard may not have
AltRight key.
If user emulates AltGr key, we should set MODIFIER_ALTGRAPH to a set of
keyboard events for printable keys only when the key press produces
character(s) or a dead key. For example:
1. ControlLeft keydown event should make ctrlKey true.
2. AltLeft keydown event should make altKey true (not AltGraph state).
3. ctrlKey and altKey of printable keydown, keypress and keyup events should be
set to false, but getModifierState("AltGraph") should return true.
4. AltLeft keyup event should make altKey false.
5. ControlLeft keyup event should make ctrlKey false.
(If AltLeft key is pressed first, altKey of AltLeft keydown is true and
both altKey and ctrlKey of the following ControlLeft keydown are true as
usual.)

KeyboardLayout::InitNativeKey() takes |const ModifierKeyState&| as its
argument with NativeKey reference and it calls some internal methods with
the given ModifierKeyState without any changes. Additionally, its caller
is only NativeKey::InitWithKeyChar() and its called with given NativeKey
instance's mModKeyState. So, removing the redundant arguments from
some methods makes them clearer what they compute with.
So, this patch does not change any behavior.
