AccessibleCaretEventHub is an nsISelectionListener of Selection whose type is
"normal". This is added only when nsFrameSelection::Init() is called and
accessible caret is enabled. Additionally, nsFrameSelection::Init() is
always called immediately after creating nsFrameSelection.
Therefore, when AccessibleCaretEventHub is installed to Selection, this is
always second selection listener and won't be installed multiple times. So,
Selection can store pointer of AccessibleCaretEventHub directly only when
it's enabled and the Selection needs to notify it of selection change.
This patch makes Selection stores AccessibleCaretEventHub with RefPtr, then,
makes Selection::NotifySelectionListeners() call its OnSelectionChange()
immediately after AutoCopyListener.
Unfortunately, this patch includes making of MOZ_CAN_RUN_SCRIPT_BOUNDARY and
MOZ_CAN_RUN_SCRIPT a lot since some methods of AccessibleCaretEventHub are
marked as MOZ_CAN_RUN_SCRIPT and including AccessibleCaretEventHub.h into
Selection.h causes compile the compile errors.

-Wmissing-prototypes is a new optional warning available in clang ToT. It warns about global functions that have no previous function declaration (e.g. from an #included header file). These functions can probably be made static (allowing the compiler to better optimize them) or they may be unused.
Confusingly, clang's -Wmissing-prototypes is equivalent to gcc's -Wmissing-declarations, not gcc's -Wmissing-prototypes. A function prototype is a function declaration that specifies the function's argument types. C++ requires that all function declarations specify their argument types, but C does not. As such, gcc's -Wmissing-prototypes is a C-only warning about C functions that have no previous function *prototypes* (with argument types), even if a previous function *declaration* (without argument types) was seen.

In the era of B2G, we wanted to hide the carets during scrolling, and
PostScrollState was designed to avoid carets flicking during momentum
scrolling.
These days, we no longer hide carets during scrolling, so PostScrollState
can be removed to make the code simpler and easier to maintain.

The accessible caret manager is owned by the event hub, that is owned by the
shell.
All the callers of methods that call FlushLayout on the AccessibleCaretManager
should hold an external reference to the event hub.
Flushing pending notifications can run arbitrary script, that can call Destroy()
on the pres shell (and thus tear down the accessible caret event hub, and the
manager with him).
I don't know why before my change this wasn't crashing badly, but the code as it
was just doesn't look sound to me at all either (maybe I'm misunderstanding
something and I should just revert that patch and give up on having nice
invariants during our flushes..., but I don't think it's the case).
This also adds some sanity-checking that we don't die under our flush.

Override OnScrollPositionChanged() in ScrollState because we want to update
carets during scrolling in subframes without APZ.
Due to the observation in bug 1273045 comment 8, we do not distinguish
PositionChangedResult::NotChanged and PositionChangedResult::Changed.
Instead, we always update caret even if its position is not changed.
To avoid excessive CaretStateChangedEvents are dispatched in
OnScrollPositionChanged(), we add IsScrollStarted to distinguish whether
OnScrollStart() is called or not.

On desktop, the context menu is shown when the user lifts their finger after
a long press, but only if the eMouseLongTap event is not cancelled. So by
not cancelling it, we allow both the text selection and the context menu.
On Android, the context menu takes priority over text selection, so this
has no effect (i.e. if the context menu is shown, then the AccessibleCaret
code never even gets the eMouseLongTap event). Also on Android nothing
else relies on the cancellation of the eMouseLongTap event, so this change
is a no-op.

Add a pref "layout.accessiblecaret.always_show_when_scrolling" defaults
to true on all platforms except b2g. When it is set to false, the carets
will be hidden during scrolling, which is the current behavior before
applying this change.
The pref "layout.accessiblecaret.extendedvisibility" was added for
Fennec to keep ActionBar open when carets temporarily hiding during
panning or zooming. Now we make carets always show by default, so the
pref can be removed. However, the floating toolbar still need to be
notified when the scrolling begins, so we dispatch "scroll" instead.
In gtest, the preference changes were in the middle of the test
function. To make the preference change clearer, I add new pref changes
or move the existing ones to the beginning of the test functions.
The 250ms transition effect added in ua.css is per request of UX

In my original design, I treat eTouchCancel to be like eTouchEnd for
ending a caret dragging procedure.
However when pointer events is enabled, it sents an eTouchCancel event
after the eTouchStart event whose primary usage is to be converted to
pointer events, which then cancels the normal caret dragging procedure.
Moreover, when pointer events is disabled, we don't get eTouchCancel
during a normal caret dragging scenario, so we don't really need to
handle eTouchCancel anyway.

After calling FlushLayout(), PresShell::Destroy() might be called and we
should consider PresShell and other resources will be no longer valid.
Before this patch, AccessibleCaretManager and AccessibleCaret(s) are
deallocated in PresShell::Destroy(). However FlushLayout() are all
invoked in AccessibleCaretManager, we need to keep manager alive to
clean up after PresShell::Destroy().
This patch makes AccessibleCaretManager live after PresShell::Destroy(),
and use IsTerminated() to check whether PreShell is vaild after each
FlushLayout() calls.
Note that event though AccessibleCaretEventHub will be unref in
PresShell::Destroy(), all the callers to AccessibleCaretEventHub's
public methods already add a ref to AccessibleCaretEventHub. So we don't
need to worry about AccessibleCaretEventHub and AccessibleCaretManager
die immediately after PresShell::Destroy().

Fennec enables sCaretsExtendedVisibility which uses
Appearance::NormalNotShown instead of Appearance::None to keep actionbar
shown during scrolling. This breaks selection mode update when the
positions of the carets are not changed after scrolling.
To fix this, we need to implement appearance recovering for selection

UpdateCaretsForSelectionMode() respects UpdateCaretsHint.

Currently, the caret in cursor mode is always hide after scrolling. I
think it's better to restore its appearance if it's logically visible
before scrolling. That is:
1) If the caret is logically visible (Normal or NormalNotShown) before
scrolling, update carets on scroll-end to show the caret again.
2) If the caret is hide due to timeout or blur, it should remain hidden
on scroll-end.

In AccessibleCaretEventHub, it is not accurate to use APZ enabled to
determine whether to use long tap injector. On desktop browser, there's
no long tap events even if APZ is enabled. We should use a preference to
control that.
Since it's a fact the APZ on b2g has long tap events, we should use
preference to disable long tap injector so that when long tap events
stop dispatching to AccessibleCaretEventHub, we'll know immediately.
Delete SetUseAsyncPanZoom() usage in gtest since APZ is not related to
scrolling in AccessibleCaretEventHub.
