The BothFingersLifted() mechanism was a bit of a hack to handle the case that
with touch inputs, a user might be able to lift just one finger to transition
from a pinch to a pan or other kind of gesture. This isn't possible with
other kinds of pinch gestures, such as on trackpads or with mousewheels.
So instead of tracking that via special-case behaviour of mFocusPoint, or
adding an extra bool to the PinchGestureInput class, it seems cleaner to
separate the concerns by adding a new type of input event that explicitly
covers the "finger lifted" touch scenario. This patch implements this change,
and removes the BothFingersLifted() machinery.

To correctly implement this, it must be known on instantiation whether E is
copy-constructible, which is not the case if only a forward declaration is
available. This can be resolved either by making sure a full definition of E is
available, which is preferable. But in cases where this is not (easily) possible,
the information can be explicitly provided by the MOZ_DECLARE_COPY_CONSTRUCTIBLE
and MOZ_DECLARE_NON_COPY_CONSTRUCTIBLE macros. In particular, declarations for
IPDL-declared types are added to nsTArray.h itself, like it was already done
for MOZ_DECLARE_RELOCATE_USING_MOVE_CONSTRUCTOR.

We currently use ParentLayer pixels in GestureEventListener, it should
be Screen pixels because we care about physical distances and
thresholds, not layer-relative ones.

These macros tend to be handled quite poorly since the clang-format
tokenizer cannot figure out how to handle them.

This commit implements the auto-dir scrolling functionality in APZ, based on
part 1 to part 3. However, the functionality of mousewheel.autodir.honourroot
will be implemented in a future.

This remotes the APZInputBridge interface over the PAPZInputBridge
protocol in the case of the GPU process, and makes the GPU process'
main thread act as the APZ controller thread in that process. If
there is no GPU process we continue as before and the APZInputBridge
interface implementation is the concrete APZCTreeManager instance
in the UI process.
The main changes in this patch are moving all the code associated with
these messages out of APZCTreeManager{Parent,Child} and into
APZInputBridge{Parent,Child}. APZCTreeManagerChild now returns an
APZInputBridgeChild instance via InputBridge(), instead of returning
itself. The SetControllerThread call in the GPU process is also updated.

This allows us to fire MozMouseHittest events from tests and then read
the hittest result from the compositor APZTestData. The MozMouseHittest
event was chosen in particular because the existing uses of it are
similar in nature - it is a dummy event that is used to determine what
elements a particular coordinate targets. It is also an event that is
never generated by the OS and so using this event gives us more control
over what ends up in the APZTestData.

This commit adds code for keyboard scroll animations and computing the delta
needed for a keyboard scroll action. Keyboard scrolling behavior is more complex
with scroll snapping, so we don't support async keyboard scrolling when we have
scroll snap points.

Focus can change at any moment in a document. This causes non-determinism and
correctness problems for doing keyboard apz scrolling. To get around this, we
will maintain deterministic behavior for focus changes initiated by input events
and see if we can get away with more non-determinism for things like `setTimeout`
In order to do this, we disable async keyboard scrolling when an input event is
processed that could have a event listener. We then attach a sequence number to
that input event and dispatch it to content. In content, we record the highest
sequence number that we have processed from an event, and send that on each focus
update. Using this, we can determine in APZ if we have a current focus target or
if we are still waiting for an input event to be processed and focus to be
reconfirmed.

Every event type handled by APZ needs to have a InputData type. This commit
adds a new KeyboardInput type that stores the minimum fields needed to match
keyboard shortcuts.

This version of the Dynamic Toolbar moves the animation of the toolbar
from the Android UI thread to the compositor thread. All animation for
showing and hiding the toolbar are done with the compositor and a static
snapshot of the real toolbar.
