The DoMouseClick helper is also removed because no other caller can now pass a null aEvent. Other MouseClicked implementations are also updated since aEvent cannot be null, which was already the case.

This was done automatically replacing:
s/mozilla::Move/std::move/
s/ Move(/ std::move(/
s/(Move(/(std::move(/
Removing the 'using mozilla::Move;' lines.
And then with a few manual fixups, see the bug for the split series..

In this case we have a shadow hoot with display: contents, with no children.
Those children wouldn't be flattened tree children of the shadow host.
Instead of using the last light dom child and seek to it, use
FlattenedChildIterator's reverse iteration.

Currently, NAC always inherits from the closest non-NAC ancestor element,
regardless of whether it is for an element-backed pseudo or not.
This patch changes the inheritance so that for element-backed pseudos, we
inherit from the closest native anonymous root's parent, and for other NAC we
inherit from the parent.
This prevents the following two issues and allows us to remove the
NODE_IS_NATIVE_ANONYMOUS flag:
* Avoiding inheriting from the non-NAC ancestor in XBL bindings bound to NAC.
- This is no longer a problem since we apply the rule only if we're a
pseudo-element, and all pseudo-elements are in native anonymous subtrees.
- This also allows to remove the hack that propagates the
NODE_IS_NATIVE_ANONYMOUS flag from the ::cue pseudo-element from
BindToTree.
* Inheriting from the wrong thing if we're a nested NAC subtree.
- We no longer look past our NAC subtree, with the exception of
::-moz-number-text's pseudo-elements, for which we do want to propagate
::placeholder to.
A few rules from forms.css have been modified because they're useless or needed
to propagate stuff to the anonymous form control in input[type="number"] which
previously inherited from the input itself.

Second test-case is because I initially made this code work with
display: contents. But then realised that display: contents meant allowing
Shadow DOM in there, which I don't really want to deal with right now.

After bug 1303605 we can assert this, since we make sure all children have the
same flattened tree parent, and thus insertion point.

What happened in bug 1446368 is the following: We append two items to an empty
listbox.
We can't construct lazily because this is XUL, so that goes through
IssueSingleInsertNotifications for each of the items.
When we insert the first one we call LazilyStyleNewChildRange _only on the first
sibling_, yet the listbox code tries to construct frames for the next sibling
too from CreateRows. The next sibling is unstyled, so we panic.
Instead of handling it in ContentRangeInserted but not ContentAppended, just do
it in the listbox-specific code instead, which looks slightly cleaner (though we
can't assert we're constructing async).
This should fix the case where the listbox is display: none or what not which,
combined with the patch in bug 1303605, supersede the backed out patch in
bug 1429088, which was backed out because listboxes suck.

Move the assertion to the earliest point where it can happen instead, and do it
automatically on exit if it's generated content instead of relying on manual
calls.

This also adopts the resolution of [1] while at it, and switches XUL to not
support display: contents until a use case appears.
This makes our behavior consistent both with the spec and also in terms of
handling dynamic changes to stuff that would otherwise get suppressed.
Also makes us consistent with both Blink and WebKit in terms of computed style.
We were the only ones respecting "behaves as display: none" without actually
computing to display: none. Will file a spec issue to get that changed.
It also makes us match Blink and WebKit in terms of respecting display: contents
before other suppressions, see the reftest which I didn't write as a WPT
(because there's no spec supporting neither that or the opposite of what we do),
where a <g> element respects display: contents even though if it had any other
kind of display value we'd suppress the frame for it and all the descendants
since it's an SVG element in a non-SVG subtree.
Also, this removes the page-break bit from the display: contents loop, which I
think is harmless.
As long as the tests under style are based in namespace id / node name /
traversal parent, this should not make style sharing go wrong in any way, since
that's the first style sharing check we do at [2].
The general idea under this change is making all nodes with computed style of
display: contents actually honor it. Otherwise there's no way of making the
setup sound except re-introducing something similar to all the state tracking
removed in bug 1303605.

This method is not a virtual call, and also looks nicer.
This patch was mostly generated by a Python script, but I manually
cleaned up the code in a few places where statements didn't need to be
split across multiple lines any more.

Much in the spirit of bug 1442207.
They're not only unneeded, and cheap to get, but also we call them
inconsistently with the light DOM and flattened tree parent (like ContentRemoved
for display: contents), so they're really confusing, and kind of a footgun.
MozReview-Commit-ID: 9u3Kp8Kpp5i
The code was trying to assert that we had frames constructed for all the nodes
in the parent chain, but we don't bail out in the
!GetContentInsertionFrameFor(aContainer) in the case that it's a children
element, because they actually have no insertion frame, though their children
do.
Move the LazyFC check after the insertion point check. That makes the previous
check work on the insertion point of the child, which makes it sound.
This also fixes bug 1410020, and with it a Shadow DOM test-case that was failing
because we had two sibling assigned to two different <slot>s, and the second one
wasn't getting properly flagged, and thus the second sibling never got a frame.
The other two test failures in this test are an event dispatch failure, where
the position of the target is not what the test expects (we don't account for
margin and padding). Filed that as bug 1450027.
Also, added a test for which we have wrong layout without these patches, and
that crashes with "Called Servo_Element_IsDisplayNone" with the first patch of
this bug applied but not this one, due to the bogus check mentioned above.

This is mostly code removal, changing GetDisplayContentsStyle(..) checks by an
FFI call to Servo.
The tricky parts are:
* MaybeCreateLazily, which I fixed to avoid setting bits under display: none
stuff. This was a pre-existing problem, which was wallpapered by the
sc->IsInDisplayNoneSubtree() check, which effectively made the whole
assertion useless (see bug 1381017 for the only crashtest that hit this
though).
* ContentRemoved, where we can no longer know for sure whether the element is
actually display: contents if we're removing it as a response to a style
change. See the comment there. That kinda sucks, but that case is relatively
weird, and it's better than adding tons of complexity to handle that.
* GetParentComputedStyle, which also has a comment there. Also, this function
has only one caller now, so we should maybe try to remove it.
The different assertions after DestroyFramesForAndRestyle are changed for a
single assertion in the function itself, and the node bit used as an
optimization to avoid hashtable lookups is taken back.

Tag is unused.
This changes how some mixes of MathML and html get wrapped in anonymous table
boxes (in particular, it changes whether it uses a MathML or an HTML table
frame). The main thing this affects is whether the frame responds to certain
attributes. Responding to mathml attributes on its mContent when that mContent
is not a MathML element is weird. So arguably this is also more correct.
However, that seems acceptable to me, and you can already get that mixing
manually. On a few (arguably simple) manual test-cases mixing MathML and HTML
tables I couldn't manage to get the patched build to render differently.
Plus, neither our reftests nor the WPT MathML test-suite upstreamed by Fred Wang
for WebKit rely on this.

We don't extend svg elements, except in a lone test, that isn't really impacted
by this.
I agree this should look at the frame btw, though that looks a bit out of scope
for this bug.

The new StaticPrefs machinery means that StylePrefs can be removed.
Note that this approach mirrors all static prefs into Rust, but I have only
updated structs.rs for the prefs that Stylo uses.
On a CLOSED TREE, since a sheriff closed the tree while I was about to land this
via autoland.

This patch basically does:
* remove StyleSetHandle and its corresponding files
* revisit #includes of related header files and change correspondingly
* change nsIPresShell::mStyleSet to be UniquePtr<ServoStyleSet>
* change the creating path of ServoStyleSet to pass UniquePtr
* change other mentions of StyleSetHandle to ServoStyleSet*
* remove AsServo() calls on ServoStyleSet
Some unfortunate bits:
* some methods of (Servo)StyleSet only accepts ServoStyleSheet while
many places call into the methods with StyleSheet, so there are many
->AsServo() added to sheets

The old style system used FlattenedTreeIterator for lazy frame construction.
That could not find native anonymous nodes, so we had to construct eagerly in
native anonymous subtrees. Servo uses StyleChildrenIterator for the same
purpose, and that knows about native anonymous content, so we can now do lazy
construction for it.
Also, not check the container to do lazyFC on the children, it's no longer
necessary to check for anon content, and the reason we check for XUL is because
of XBL bindings, and those are loaded for the parent already, if we're about to
construct frames for the children.
Also, assert more tightly, we don't insert NAC lazily, that makes no sense.
Well, to be fair editor does insert anonymous nodes lazily sometimes (see al the
ManualNAC machinery), but it goes through the PostRecreateFramesFor path, not
through ContentInserted / LazyFC.
