LSBUtils closes a file descriptor twice, once with fclose and then again with
close. It also does this on a background thread, during startup, which means
it tends to race with main thread code which opens files.
This patch fixes that, and also removes a work-around for the issue in the
MemMapSnapshot code.

Some odd mouse drivers try to activate a window which the mouse driver wants to
scroll its content (such window is typically under the mouse cursor when mouse
wheel is turned). However, this is illegal behavior and such odd mouse drivers
try to activate our popup windows which won't be activated without such apps.
We prevented this odd focus behavior with fixing of bug 953146. However, it
did NOT stop notifying widget listener of activating nor inactivating the
windows. Therefore, that caused a lot of reflow for supporting
-moz-window-inactive pseudo class.
This patch makes nsWindow::DealWithPopups() consume WM_ACTIVATE message before
nsWindow::ProcessMessage() because nsWindow::ProcessMessage() notifies widget
listener of activating and inactivating window even when focus move from and to
our popup window. So, in other words, this patch stops notifying widget
listener of activating and inactivating window when focus moves from/to
a popup window.

When user removes all composition string of MS Pinyin, MS Wubi, MS ChangJie and
MS Quick with Backspace key, IME commits last character temporarily and
restart composition to replace the last character with empty string when
user tries to remove last one character.
This causes flicking composition string because the additional composition
selects the character and it may be painted immediately before removed, and
also editor will have unnecessary undo transaction.
Therefore, as same as bug 1208043, TSFTextStore::RecordCompositionStartAction()
should restart last composition in such case. Fortunately, we implemented
similar code for bug 1208043, however, unfortunately, we don't have preceding
pending compositionstart in this case. Therefore, this patch makes
pending compositionend store start offset of composition. Then, we can
restart composition only with information stored by pending compositionend
action. Additionally, this patch renames the method checking pending
actions for self-describing the new meaning.

TextEditor modifies composition string or selected string when first
eCompositionChange event is received. However, TextComposition dispatches
eCompositionChange event ("text" event of DOM) only when composition string
becomes non-empty if current composition string is empty. So, when IME
dispatches only eCompositionStart and eCompositionCommit events for removing
selected text, TextEditor does nothing. This hacky behavior is used by
MS Pinyin on Windows 10 at least.
For supporting this behavior, we need to make TextComposition dispatch
eCompositionChange event when eCompositionChange(AsIs) event is fired
even before dispatching eCompositionChange event.
Although from point of view of web apps, the hacky composition should be
merged into the previous composition if it's possible but it's out of scope
of this bug.

Use wl_keyboard_listener and keymap event to get key mapping on Wayland. Weston simple-im.c example
is used as a reference implementation and actual key modifiers are derived from Wayland/GDK code from
gdkkeys-wayland.c.

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.
