Synthetic mouseevents generated from touch gestures are dispatched asynchronously
from the touch events. This means that the nsAutoRollup that the widget puts on
the stack during the dispatching of the touch events is no longer in scope when
we get around to firing the mouse events. As a result, the mouse events can end
up reopening rollups that got closed by the touch events and that shouldn't be
reopened. We fix this by stashing the rollup that was in scope while the touch
events were being dispatched, and make sure we keep that in scope for the
synthetic mouse events.

We now call NotifyAsyncPanZoomStarted/Stopped precisely on the document
which is being transformed, so we no longer need to notify the child
docshells which was added in Bug 1088559.
Remove the |nsIDocument| argument for ProcessAPZStateChange(), which is not
used anymore.
mActiveAPZTransforms added in bug 1142926 is removed because AccessibleCaret
is the only consumer for AsyncPanZoomStarted/Stopped, and it now defaults to
always show while scrolling, i.e.
"layout.accessiblecaret.always_show_when_scrolling" defaults to true. And I
cannot reproduce the bug even if I turn off the preference.

On Windows, the contextmenu event is fired when the finger is lifted after a
long-press. However, there are various bits of code, such as the AccessibleCaret
or potential fixes for bug 1147335, which would benefit from knowing when the
long-press gesture was detected. By moving eMouseLongTap event up we can satisfy
that need. An alternative approach considered was to fire the eMouseLongTap
before the contextmenu on all platforms unconditionally, but that makes it harder
to implement platform-specific text selection behaviour the way we want. In
particular we would have to add an extra message or notification for non-Windows
platforms that initiated text selection if the contextmenu event was not
consumed.

This patch prevents the Windows widget code from dispatching the contextmenu
event if APZ is handling touch input. Instead, the APZ code processes the
raw touch input, and will fire a contextmenu event when the user lifts their
finger after a long-press action, in keeping with the Windows platform
convention. Doing it this way also allows us to respect web conventions where
the web content can prevent the contextmenu event from firing by calling
preventDefault on the touchstart event; this was not possible when dispatching
the contextmenu event directly from the widget code.
This also makes long-pressing on browser chrome components work properly, as
it just shifts the point in time that the contextmenu event is fired without
changing any of the code that triggers the XUL popup. However, some changes
were needed to have the widget code ignore the synthetic mouse events that
the Windows platform sends us, because those would otherwise immediately
dismiss the contextmenu popup after it appeared.

This patch makes the following changes on many in-class methods.
- NS_IMETHODIMP F() override; --> NS_IMETHOD F() override;
- NS_IMETHODIMP F() override {...} --> NS_IMETHOD F() override {...}
- NS_IMETHODIMP F() final; --> NS_IMETHOD F() final;
- NS_IMETHODIMP F() final {...} --> NS_IMETHOD F() final {...}
Using NS_IMETHOD is the preferred way of marking in-class virtual methods.
Although these transformations add an explicit |virtual|, they are safe --
there's an implicit |virtual| anyway because |override| and |final| only work
with virtual methods.
There were a couple of problems when delivering tap gestures to content with
full zoom applied. One was that the ConverToGecko function converted the coords
into "CSS pixel" space by using the web content's CSS-to-LD scale, but also
applied that on the translation from the chrome area. Moving that conversion
to later in the process (after the coords got passed through TabParent::
AdjustTapToChildWidget) corrected that issue.
The other problem was that bits of code in APZEventState and APZCCallbackHelper
were using the widget->GetDefaultScale() value as the CSS-to-LD scale, but that
omitted the full zoom value. Getting the CSS-to-LD scale from the presShell and
propagating that through corrected that issue.

For B2G we had this "special" behaviour where a long-press that didn't trigger
a contextmenu or whose contextmenu event was cancelled would still trigger a
click event. No other browser does this, and so I think it doesn't make sense
for us to keep doing it either. It also makes it much harder to implement the
Windows-style contextmenu, where the contextmenu pops up when you *lift* your
finger after doing a long-press.

This patch also cleans up some inconsistencies in the conditions under which the
main thread would respond to wheel and mouse events. With this patch applied, the
main-thread notifications are only sent if the input block id is nonzero, which
indicates the APZ actually processed the input event and added it to an input
block.
