`Selection::Extend()` is too slow but editor and ContentEventHandler use it in
some places. We should make them use `Selection::SetStartAndEndInLimiter()` or
`Selection::SetBaseAndExtentInLimiter()`. The former is usable only when caller
guarantees the start point is prior to the end point in the DOM tree.
Otherwise, we need to use the latter even though it's slower than the former.

DataTransfer should have more 2 constructors. One takes |const nsAString&| and
sets its data to the string. The other takes |nsITransferable*| and stores only
its data with DataTransferItem.
If given data is external resource like the case of `HTMLEditor::PasteTransferable()`,
we should copy its data to each DataTransferItem because nsITransferable is not
cycle-collectable, but DataTransfer may be grabbed by JS. Unfortunately, adding
new path to initialize DataTransfer with nsITransferable instance is too risky
because DataTransfer and DataTransferItem work together to initialize each of
them if DataTransfer is in external mode. Therefore, this patch makes the
new constructor temporarily sets it to in external mode, then, cache usable types
first, then, call `FillAllExternalData()` to make each DataTransferItem initializes
its data by itself, finally, make the constructor set it to internal mode and release
nsITransferable instance. This is ugly implementation but the most reasonable
way for now because:
- We don't need to change DataTransfer nor DataTransferItem a lot in this bug.
- We don't need to duplicate any code like a loop in `CacheExternalData()`.
In another bug, we should redesign DataTransfer and DataTransferItem to
make DataTransferable easier to be added new constructors.

When preceding mouse event is handled, that may cause changing style of the
target. Therefore, when an eMouseDown or eMouseUp event is handled, handlers
require the latest layout. Currently, nsViewManager::DispatchEvent() tries
to guarantee that with calling nsIPresShell::FlushPendingNotifications()
with FlushType::Layout. However, this just flushes the pending layout in
the PresShell associated with the nsViewManager instance. I.e., if the
target is in a child PresShell, its layout hasn't been flushed.
This patch makes PresShell::EventHandler::HandleEvent() flush pending
notifications at first of handling events using coordinates (only when
eMouseDown or eMouseUp, though). Then, when it realizes that the event
should be handled in a child PresShell, makes it flush its pending
notifications and then, recompute event target with the latest layout if

Bug 1514594: Part 3a - Change ChromeUtils.import to return an exports object; not pollute global. r=mccr8
This changes the behavior of ChromeUtils.import() to return an exports object,
rather than a module global, in all cases except when `null` is passed as a
second argument, and changes the default behavior not to pollute the global
scope with the module's exports. Thus, the following code written for the old
model:
ChromeUtils.import("resource://gre/modules/Services.jsm");
is approximately the same as the following, in the new model:
var {Services} = ChromeUtils.import("resource://gre/modules/Services.jsm");
Since the two behaviors are mutually incompatible, this patch will land with a

When user middle clicks a link, most users must not expect to expose clipboard
content to the web application. Therefore, we should stop firing paste event
when user click a link with middle button.
This patch makes ClickHandlerChild.handleEvent() prevent multiple action
when it posts middle click event on a link. Note that even if middle click
event is consumed, default event handler will dispatch paste event.
Unfortunately, this is compatible behavior with the other browsers.
Therefore, we cannot change this behavior with calling preventDefault() and
this is the reason why this patch adds Event.preventMultipleActions().
Out of scope of this bug though, if there is an element which looks like a
link but implemented with JS, web apps can steal clipboard content if user
enables middle click event and user just wants to open the link in new tab.
It might be better to stop dispatching paste event in any browsers and request
to change each web apps.

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.
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.

"text" event is Mozilla specific event, not in any standards. The event follows
"compositionupdate" event and editor modifies composition string when receives
the event in the system group.
So, we'd like to stop dispatching this unnecessary event but we need to get

This patch re-enables the new behavior of bug 1479964, to set keyCode or
charCode of keypress event whose value is zero to the other's non-zero value.
However, some web apps are still broken with the new behavior. Therefore,
this patch adds a blacklist to keep using our legacy behavior in some specific
web apps.
Note that Google Docs, Gmail and Remember The Milk are reported as broken.
However, I don't see any broken shortcut with Gmail. Therefore, this patch
adds only Google Docs and Remeber The Milk into the blacklist.

The pointerType field in the pointer event will reveal the details of
users' hardware; this is a fingerprinting vector. So, we would spoof all
types of pointer events into mouse type pointer events for protecting
users from browser fingerprinting when fingerprinting resistance is on.
In this patch, we would spoof the pointerType as well as other fields
that mouse pointer events don't support, like pressure, tiltX/Y and so
on when fingerprinting resistance is on.

This patch makes EventStateManager handle middle click paste as a default
action.
Unfortunately, we cannot remove the call of HandleMiddleClickPaste() in
EditorEventListener because it's important to consume middle click event
before any elements in the editor. For example, if clicked HTMLEditor has
non-editable <a href> element, middle click event needs to be handled by the
editor rather than contentAreaUtils which handles click events of <a href>
elements. The cause of this kind of issues is, any click event handlers
which handle non-primary button events still listen to "click" events.
Therefore, this patch makes HandleMiddleClickPaste() do nothing if the mouseup
event is fired on an editor.

This is preparation of the last patch. Even if no editor is clicked with
middle button, we need to do:
- collapse Selection at the clicked point.
- dispatch "paste" event.
Therefore, HandleMiddleClickPaste() should dispatch ePaste event by itself
and each editor methods should have a bool argument which the caller wants
ePaste event automatically.
Note that Chromium dispatches "paste" event and pastes clipboard content
into clicked editor even if preceding "auxclick" event is consumed.
However, our traditional behavior is not dispatching "paste" event nor
pasting clipboard content. Unless Chromium developer keeps their odd
behavior, we should keep our traditional behavior since our behavior is
conforming to DOM event model.

We need to move EditorEventListener::HandleMiddleClickPaste() into
EventStateManager to handle middle click paste after all click events are
dispatched. This is preparation of the change.
HandleMiddleClickPaste() uses UIEvent::GetRangeParent() and
UIEvent::RangeOffset() to collapse Selection at clicked point. However,
EventStateManager cannot access them since EventStateManager can handle it
with WidgetMouseEvent. Fortunately, only WidgetMouseEvent is necessary for
implementing them. Therefore, we can move the implementation into
nsLayoutUtils and merge them.

EventStateManager::InitAndDispatchClickEvent() sends given nsEventStatus to
nsIPresShell::HandleEventWithTarget(). Then, it sends the status to
EventStateManager::PreHandleEvent() before dispatching the event. At this
time, EventStateManager::PreHandleEvent() resets the state to
nsEventStatus_eIgnore. Therefore, for example, if eMouseClick event is
consumed but eMouseAuxClick is ignored, the event status result is
nsEventStatus_eIgnore. So, neither DispatchClickEvents() nor
PostMouseUpEventHandler() cannot check whether at least one click event
is consumed.
This patch makes EventStateManager::InitAndDispatchClickEvent() sends
local variable of nsEventStatus to nsIPresShell::HandleEventWithTarget().
Then, merge the result with current status.
If we'd change nsEventStatus to enum class, we could make this change as
custom "operator|=" or something.

Chrome sets both KeyboardEvent.keyCode and KeyboardEvent.charCode of "keypress"
event to same value. On the other hand, our traditional behavior is, sets
one of them to 0.
Therefore, we need to set keyCode value to charCode value if the keypress
event is caused by a non-function key, i.e., it may be a printable key with
specific modifier state and/or different keyboard layout for compatibility
with Chrome. Similarly, we need to set charCode value to keyCode value if
the keypress event is caused by a function key which is not mapped to producing
a character.
Note that this hack is for compatibility with Chrome. So, for now, it's enough
to change the behavior only for "keypress" event handlers in web content. If
we completely change the behavior, we need to fix a lot of default handlers
and mochitests too. However, it's really difficult because default handlers
check whether keypress events are printable or not with following code:
> if (event.charCode &&
> !event.altKey && !event.ctrlKey && !event.metaKey) {
or
> if (!event.keyCode &&
> !event.altKey && !event.ctrlKey && !event.metaKey) {
So, until we stop dispatching "keypress" events for non-printable keys,
we need complicated check in each of them.
And also note that this patch changes the behavior of KeyboardEvent::KeyCode()
when spoofing is enabled and the instance is initialized by initKeyEvent() or
initKeyboardEvent(). That was changed by bug 1222285 unexpectedly and keeping
the behavior makes patched code really ugly. Therefore, this takes back the
old behavior even if spoofing is enabled.

Correctness improvements:
* UTF errors are handled safely per spec instead of dangerously truncating
strings.
* There are fewer converter implementations.
Performance improvements:
* The old code did exact buffer length math, which meant doing UTF math twice
on each input string (once for length calculation and another time for
conversion). Exact length math is more complicated when handling errors
properly, which the old code didn't do. The new code does UTF math on the
string content only once (when converting) but risks allocating more than
once. There are heuristics in place to lower the probability of
reallocation in cases where the double math avoidance isn't enough of a
saving to absorb an allocation and memcpy.
* Previously, in UTF-16 <-> UTF-8 conversions, an ASCII prefix was optimized
but a single non-ASCII code point pessimized the rest of the string. The
new code tries to get back on the fast ASCII path.
* UTF-16 to Latin1 conversion guarantees less about handling of out-of-range
input to eliminate an operation from the inner loop on x86/x86_64.
* When assigning to a pre-existing string, the new code tries to reuse the
old buffer instead of first releasing the old buffer and then allocating a
new one.
* When reallocating from the new code, the memcpy covers only the data that
is part of the logical length of the old string instead of memcpying the
whole capacity. (For old callers old excess memcpy behavior is preserved
due to bogus callers. See bug 1472113.)
* UTF-8 strings in XPConnect that are in the Latin1 range are passed to
SpiderMonkey as Latin1.
New features:
* Conversion between UTF-8 and Latin1 is added in order to enable faster
future interop between Rust code (or otherwise UTF-8-using code) and text
node and SpiderMonkey code that uses Latin1.
