In the current blocklist implementation, we read the stylo blocklist from the user
preferences very early and only once, even earlier than the test preferences
updating happens.
So, to be able to test the functionality of the stylo blocklist, we add these two
nsIDOMWindowUtils APIs to be able to add/remove a mock domain to the existing
blocklist.

In this patch, we read the stylo blocklist into nsLayoutUtils's global static
variable during nsLayoutUtils::Initialize(). So, we can decide if we should
fallback to use Gecko backend while updating style backend for a document.
We add "layout.css.stylo-blocklist.blocked_domains" and
"layout.css.stylo-blocklist.enabled" to ContentPrefs.cpp because they are read
very early (during nsLayoutUtils::Initialize).

Bug 1400459 devirtualized nsIAtom so that it is no longer a subclass of
nsISupports. This means that nsAtom is now a better name for it than nsIAtom.

This commit removes:
* layout.css.style-attr-with-xml-base.disabled pref
* deprecation XMLBaseAttributeForStyleAttr
* code path for getting base URI of style attr considering xml:base

And stop creating displayports during display list building.
One thing we can investigate in the future is whether we should use the value of mHaveScrollableDisplayPort stored on the display list builder retained between paints. If it's true then we could potentially skip this pass. It would mean that if there are large changes to the page we wouldn't set a displayport. And we'd need to make sure the value is cleared when we load a new page.
This patch merges nsAtom into nsIAtom. For the moment, both names can be used
interchangeably due to a typedef. The patch also devirtualizes nsIAtom, by
making it not inherit from nsISupports, removing NS_DECL_NSIATOM, and dropping
the use of NS_IMETHOD_. It also removes nsIAtom's IIDs.
These changes trigger knock-on changes throughout the codebase, changing the
types of lots of things as follows.
- nsCOMPtr<nsIAtom> --> RefPtr<nsIAtom>
- nsCOMArray<nsIAtom> --> nsTArray<RefPtr<nsIAtom>>
- Count() --> Length()
- ObjectAt() --> ElementAt()
- AppendObject() --> AppendElement()
- RemoveObjectAt() --> RemoveElementAt()
- ns*Hashtable<nsISupportsHashKey, ...> -->
ns*Hashtable<nsRefPtrHashKey<nsIAtom>, ...>
- nsInterfaceHashtable<T, nsIAtom> --> nsRefPtrHashtable<T, nsIAtom>
- This requires adding a Get() method to nsRefPtrHashtable that it lacks but
nsInterfaceHashtable has.
- nsCOMPtr<nsIMutableArray> --> nsTArray<RefPtr<nsIAtom>>
- nsArrayBase::Create() --> nsTArray()
- GetLength() --> Length()
- do_QueryElementAt() --> operator[]
The patch also has some changes to Rust code that manipulates nsIAtom.

The variables (basicShapeSVGBoxValues, etc.) in property_database.js are
moved to the beginning of the file so that they're defined before usage.

nsLayoutStatics::Initialize is sometimes too early to know whether a process
is an e10s parent process, or a non-e10s main process, because some prefs
get loaded later on. So we unconditionally initialize some Servo data in
nsLayoutStatics::Initialize, but we still check later on whether we are
really a non-e10s main process or e10s content process when deciding whether
to preload Servo style sheets, choose our document backend type, etc.

On-screen coordinates for points in remote frameloads are calculated relative
to the screen origin of the top-level window, while event coordinates are
calculated relative to the nearest widget. Since popups have their own widgets
separate from the top-level window, their native client offsets have no
particular relation to the origin of the top-level window, and we need to
manually calculate them relative to the origin of the top-level widget
instead.

This also moves the WithinEpsilonOf function from gfxPoint into
PointTyped, and changes call sites that are using
gfxPoint::Transform(Matrix4x4) to use Matrix4x4::TransformPoint(Point)
instead, which should be equivalent.

This commit begins the work needed for tracking focus by creating two new classes,
FocusTarget and FocusState. FocusState is created and used by APZCTreeManager to
track the global focus information, while FocusTarget is created per layer tree and
sent to APZ with local focus information. Between the two we are able to figure out
what the correct scrollable layer is to use in response to a keyboard scroll.
See the comment in `FocusState.h` for more details on the architecture and things
needed in future patches to complete this.

SupportsServoStyleBackend() uses methods in nsIDocument, so it would be more
straightforward to do that in UpdateStyleBackendType().
Also, call StyloEnabled() before doing other logic so that the warning about
"no docshell" won't show up when stylo is built but disabled.

Functions like BuildDisplayListForStackingContext or BuildDisplayListForChild look
up EffectSet property several times in callees, such as IsTransformed() or
HasOpacity(), which is time wasting.
We should look up EffectSet just once, and pass the found one to all callees
that need it.

If the percentage basis isn't provided it will be calculated from the ancestors
as before. Note that that algorithm is only valid if the frame's containing
block is the ancestor's content box, which isn't the case for grid items.
So grid layout MUST provide a percentage basis, although the given value may
be NS_UNCONSTRAINEDSIZE for either axis if the value is indefinite.
