- Create wheel transactions for wheel events handled by APZ.
- Group wheel events with the current wheel transaction, so that all
wheel events in a wheel transaction are fired to the same element.
- Store the current event target for the first event in a wheel
transaction to be used for subsequent events.
- Add the dom.event.wheel-event-groups.enabled preference as a feature
flag for this behavior.

It only has an effect on macOS, and it's only used for
scrollbars/resizers/trees. We already hard-coded <browser>
to behave as never so do the same consistently, see bug 1519905.
This reduces noise when inspecting scrollbars (and it's simpler).
No behavior change.

Move most the event handling stuff to the DOM. I've left nsMenuBarFrame
for now, but I will be removing that in the future.
The basic set up is:
* nsMenuParent becomes XULMenuParentElement (menubar or popup, manages
the current active menu item)
* nsMenuFrame -> XULButtonElements that return true for IsMenu().
Can't use XULMenuElement because of <button type=menu>, which
behaves like a, well, menu.
This makes the a11y events for menus (DOMMenuItem{Active,Inactive}) make
sense (before that we were firing duplicate Inactive events etc, and the
event order was rather suspicious).

HTMLSelectEventListener changes are needed, since currently that code works somewhat by accident given that
mTime often contains totally bogus values, like PR_IntervalNow(). Those changes then reveal issues also in
browser_editAddressDialog.js.

First, the test compares `document.querySelector(":active")` and a checkbox or
a radio button. However, Gecko activates ancestor elements too. Therefore,
Gecko returns `<html>` element or `null` for the selector. However, this is
an issue of CSS pseudo class compatibility which is **not** scope of the test.
Therefore, this patch makes it compare `document.querySelector("input:active")`
and a checkbox or a radio button instead.
Next, Gecko does not activate checkboxes and radio buttons when user presses
the space key, but the other browsers do it. Therefore, this patch makes
`HTMLInputElement::PostHandleEvent` do it and
`EventStateManager::PostHandleEvent` clear it at `keyup` of the space key.
Next, Gecko does not inactive active elements when it gets lost focus.
Therefore, this patch makes `nsFocusManager::NotifyFocusStateChange` do it
like the other browsers.
Finally, with manual testing of draft patches, I found some issues of
inactivating them when they are activated by `<label>`s. Therefore, I add new
tests in a separate file. Note that Chrome fails only in the cases testing
`<input type="radio">` with `<label>`.

[Int]CoordTyped no longer inherits Units because otherwise
instances of [Int]IntPointTyped may get one Base subobject because
it inherits Units, and others because of BasePoint's Coord members,
which end up increasing the [Int]CoordTyped's objects size (since
according to the ISO C++ standard, different Base subobject are
required to have different addresses).

The IPCDataTransfer type is used to transfer Clipboard/Drag & Drop payloads
over IPC to allow them to be written to or read from the relevant system
interfaces. Previously, the system which was used was somewhat complex, and
tried to use Shmem in some cases to store buffers out of line. Now that
BigBuffer is available, it can be simplified substantially.
In addition, this change removed the memory buffer overload of GetSurfaceData,
as the only consumer was using it to immediately send the payload over IPC as a
nsCString. It was changed to instead use `BigBuffer` as that is more efficient
in a large buffer situation, and reduces the number of required copies.

Add a dom/base/rust crate called just "dom" where we can share these.
Most of the changes are automatic:
s/mozilla::EventStates/mozilla::dom::ElementState/
s/EventStates/ElementState/
s/NS_EVENT_STATE_/ElementState::/
s/NS_DOCUMENT_STATE_/DocumentState::/
And so on. This requires a new cbindgen version to avoid ugly casts for
large shifts.

This is used by in the normal mode (i.e., not in the automation mode) to
emulate a hover at locking or unlocking a pointer capture. If it'd be possible,
we should make it handle only in the remote process, but for now, we should
make it relax for safer fix in the branches. I think that it's acceptable
because synthesizing only native mousemove events is safer than the other events.

`nsFocusManager` defines that focused content is at least `dom::Element`.
So `IMEStateManager` can handle focused content with `dom::Element` too.
Additionally, this patch makes `IMEStateManager` methods take references instead
of pointers as far as possible if they just return error for `nullptr`.

The scroll snap spec defines the concepts [1]. There are three type of scroll
operations. 1) intended end position, 2) intended direction and end position
and 3) intended direction.
Basically our existing ScrollUnits types correspond;
1) DEVICE_PIXELS, WHOLE => intended end position
2) PAGES => intended direction and end position
3) LINES => intended direction
There are two exceptions in the `intended direction and end position` case,
scrollBy() and fling gestures (on Linux). They were defined as scroll operations
with DEVICE_PIXELS unit, but the spec cleary says they are `intended direction
and end position` operations.
Note that we will also use this information for scroll-snap-stop property since
the properly will only have effects on both 2) and 3) cases.
