With this patch on its own we get some a11y tests failures, but those
are fixed on a later patch.
Combobox select no longer creates frames for its <options>, nor an
nsListControlFrame. Instead, it computes its right intrinsic size using
the largest size of the options. This is better, because we render the
option text using the select style so if the select and option styles
are mismatched it'd cause changes in the size of the select when text
changes. See the following in a build without the patch, for example:
<select>
<option>ABC</option>
<option style="font-size: 1px">Something long</option>
</select>
This seems like a rather obscure case, but it's important to get it
right, see bug 1741888.
With this patch we use the same setup in content and parent processes
(this needs bug 1596852 and bug 1744152). This means we can remove a
bunch of the native view and popup code in nsListControlFrame. A couple
browser_* tests are affected by this change and have been tweaked
appropriately (the changes there are trivial).
Not creating an nsListControlFrame for dropdown select means that we
need to move a bunch of the event handling code from nsListControlFrame
to a common place that nsComboboxControlFrame can also use. That place
is HTMLSelectEventListener, and I think the setup is much nicer than
having the code intertwined with nsListControlFrame. It should be
relatively straight-forward to review, mostly moving code from one part
to another.
Another thing that we need to do in HTMLSelectEventListener that we
didn't use to do is listening for DOM mutations on the dropdown. Before,
we were relying on changes like text mutations triggering a reflow of
the listcontrolframe, which also triggered a reflow of the
comboboxcontrolframe, which in turn updated the text of the anonymous
content. Now we need to trigger that reflow manually.
There are some further simplifications that can be done after this
lands (cleanup naming of openInParentProcess and so on, among others),
but I'd rather land this first (after the merge of course) and work on
them separately.

mColorTextSelectForeground = NS_DONT_CHANGE_COLOR;
}
that I'm removing are just broken. They were calling the version of
GetColor the function that took a default value when the color wasn't
available, not the version of the color with the outparam.
To prevent such mistakes, add two signatures, GetColor(), returning a
Maybe<nscolor> and Color(), returning a color with a fallback.

Kinda drive-by, but I think this is sane and not risky... This is used for
<select size> / <select multiple>, and only scrolls the option into view (it
only scrolls a single scroll frame, the one inside the <select>).
If the author specifies scroll-padding / margin in there I don't see why we
shouldn't respect it when doing key selection / navigation / etc.
Same for menupopups (though those are even less risky because we control the CSS
there).

According to spec, option elements with label attributes should show and use
those labels rather than their element text. So let's do that.
Requires some trickery because the option element is a block element (so it
lays out its width based on its text content) so we put its label (if it has
one) in its ::before and skip frame generation so it measures the text of its
label, not of its text node children.

The number of rows for the select dropdown can't be calculated in the content process because the dropdown has to be rendered in the parent process.
Therefore, we previously set the number of rows to 1 in this case.
That meant that the page up and page down keys only moved one item at a time for a collapsed select control, making them effectively useless.
Instead, set the number of rows to the maximum in this case.

This should be an idempotent patch. The way to come up with this patch has been:
* Run the first script attached to the bug and pipe it to xclip, then paste it
in color.rs
* Add the relevant #[derive] annotations and remove the color.mako.rs
definition.
* Reorder the values to match the ColorID definition, on which some widget
prefs and caching stuff relies on.
* Manually port some documentation from nsLookAndFeel.h
* Run `rg 'eColorID_' | cut -d : -f 1 | sort | uniq >files`
* Run the second script attached to the bug.
* Manually fix usage of `LAST_COLOR` (adding the `End` variant), and adding
casts to integer as needed.
* Add an static assert so that people remember to update the prefs, rather than
a comment on the definition :)

Unfortunately, `EventChainVisitor` does not grab the `nsPresContext` with
`RefPtr` by itself. Therefore, there is no guarantee of the lifetime without
checking the origin when its subclasses are instantiated. This patch changes
it and subclasses to `MOZ_STACK_CLASS` since only `EventDispatcher::Dispatch()`
creates them in the stack with given `nsPresContext`. Additionally, it's
already been marked as MOZ_CAN_RUN_SCRIPT_BOUNDARY`. Therefore, the
`nsPresContext` instance has already been guaranteed its lifetime by the
caller. For making this fact stronger, this patch marks their constructors
as `MOZ_CAN_RUN_SCRIPT`. Therefore, nobody can create those instances without
guaranteeing the lifetime of `nsPresContext` and `dom::Event`. Note that
it may look like that `mPresContext` of `EventChainPostVisitor` is not
guaranteed. However, `EventChainPreVisitor` which gives `nsPresContext` to it
is also a stack only class. So, it won't be deleted before
`EventChainPostVisitor` instance.

They should be CamelCase, and that's what most of them already do. This converts
the rest, which are a few.
For the ones that already used `e` or `k` prefixes, I've mostly done:
for file in $(rg Type::e layout | cut -d : -f 1 | sort | uniq); do sed -i 's#Type::e#Type::#g' $file; done
For the ones that used uppercase, I've removed the prefix if it was already in

In the case where scroll-snap-type is specified for the scroll container, the
scroll-padding is also factored into in ScrollFrameHelper::ComputeScrollSnapInfo
which is called via ScrollFrameHelper::ScrollToWithOrigin. It doesn't double
the scroll-padding value, but it's actually redundant, we should avoid it.
We could separate the functionality of ScrollToWithOrigin, one is to scroll
to a given element, the other is to scroll to a given position. The former will
be used for Element.scrollIntoElement and relevant stuff, the latter will be
used for Element.scrollTo and relevant stuff. That's being said, as of now, we
have still the old scroll snap implementation, so the separation will introduce
complexity, the separation should be done once after the old implementation
removed.
There are 9 call sites of nsIPresShell::ScrollContentIntoView:
nsIPresShell::GoToAnchor
nsIPresShell::ScrollToAnchor
Element::ScrollIntoView
We definitely needs scroll-padding and scroll-margin for these functions.
nsCoreUtils::ScrollTo
This is used for Accesible::ScrollTo which scrolls to a given accesible node,
probably we should behave as what Element::ScrollIntoView does.
Accessible::DispatchClickEvent
Similar to the above, similated various mouse events on a given target node.
PresShell::EventHandler::PrepareToUseCaretPosition
PresShell::EventHandler::GetCurrentItemAndPositionForElement
Both are for context menu, we shouldn't consider scroll-padding and
scroll-margin.
nsFormFillController::SetPopupOpen
This is used for autocompletion popup, we shouldn't consider scroll-padding
and scroll-margin.
nsFocusManager::ScrollIntoView
This is bit unfortunate, we should use scroll-padding and scroll-margin
depending on call site of this function. Bug 1535232 is for this case.
cssom-view/scrollIntoView-scrollPadding.html which has some tests that is
actually testing scroll-padding with scrollIntoView passes with this change.
The reftest in this change is a test case that the browser navigates to an
