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.

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

Originally, DisplayPort suppression was a process-global static. This change makes it possible
to control DisplayPort suppression on a per-PresShell basis.
Differential Revision: https://phabricator.services.mozilla.com/D1759
This was done automatically replacing:
s/mozilla::Move/std::move/
s/ Move(/ std::move(/
s/(Move(/(std::move(/
Removing the 'using mozilla::Move;' lines.
And then with a few manual fixups, see the bug for the split series..

For doing this, ServoComputedData is split into separate files, so that
files don't need to include ServoBindings.h just for accessing style
structs from ComputedStyles.

Now that BeginUpdate is useless for the UPDATE_STYLE case, we don't need the
update mechanism at all. Just ensure that ApplicableStylesChanged is called on
the pres shell via the relevant RuleChanged, etc. notifications.
There's a big hidden gotcha here. nsIDocument::BeginUpdate does put a script
blocker on the stack for these updates. However it's not needed, since no script
can run during these notifications (only the stylesheet events we post for
devtools, but those use AsyncEventDispatcher and PostDOMEvents, so they don't
try to run immediately).
nsIDocument::BeginUpdate also does XBL binding attached queue stuff, but we
can't change bindings during these notifications anyway, so it also doesn't
matter.

They're empty, and make PresShell::BeginUpdate useless. Now we don't have
document observers that listen for these anymore.

UI Events declares that keypress event should be fired only when the keydown
sequence produces some characters. For conforming to UI Events and
compatibility with the other browsers, we should stop dispatching keypress
events for non-printable keys.
For getting regression reports, we should enable this new behavior only
on Nightly.
However, some web apps actually broken with the standardized behavior. For
protecting testers from known broken web apps, this patch introduces a
blacklist to take the traditional behavior under specific domain (and path in
it, optionally). Currently, docs.google.com and mail.google.com are set by
default.
