There are currently some corner cases where channels that are eventually
loaded into documents (mainly <img src="data:image/svg+xml,") can inherit
expanded principals from a caller. Since documents aren't allowed to have
expanded principals, this causes crashes.
This patch is a short term workaround for the issue, until we have a longer
term solution that prevents the channels from inheriting the expanded
principals to begin with.

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.

nsDOMAttributeMap::BlastSubtreeToPieces() uses a hash table iterator
to get an arbitrary element from a hash table. This marks the hash
table as being in use. It then modifies the hash table before the
iterator is destroyed, triggering an assertion. The fix is to restrict
the scope of the iterator so that it is destroyed before the hashtable
is modified.
The existing code is safe because the iterator is never used after the
hash table has been modified.

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.

XPCOM's string API doesn't have the notion of a "null string". But it does have
the notion of a "void string" (or "voided string"), and that's what these
functions are returning. So the names should reflect that.

We don't have access to an appropriate context to create the dead wrapper in
when the callback is nuked, so instead, this patch creates a new dead wrapper
in the caller compartment each time the property is accessed. This is the same
behavior we'd get when trying to re-wrap a cross-compartment dead wrapper, so
it's consistent with the way we handle these situations elsewhere.

In order to let necko postpone the load of favicon, we have to set request context ID to the http channel that is created to load favicon.
This patch starts with passing a request context ID to nsContentUtils::LoadImage and makes other necessary changes to set the request context ID to the channel.
Right now every document in a docshell makes a copy of the list. In practice,
this list is usually pretty short (limited by depth of iframe nesting), so this
is probably not a problem. We could add a bit of complexity and have a
refcounted struct that contains the list... I wish we had something as simple
as Rust's Arc that we could use here.

It a stateless wrapper around static methods in nsHTMLTags and nsHTMLElement,
and hence an unnecessary layer of indirection that just adds complexity and
slowness. This patch removes it, cutting almost 300 lines of code.
This requires making nsElementTable.h an exported header, to expose the
nsHTMLElement methods.

With previous change, KeyboardEvent is dispatched even when invisible window
has focus. However, nsRootWindow::GetControllerForCommand() returns controller
for focused window even when the window is invisible because it uses
nsFocusManager::GetFocusedDescendant() to retrieve focused window.
Perhaps, we can assume that users won't expect to do something with invisible
window when they type some keys. Then, nsRootWindow::GetControllerForCommand()
should return controller for visible ancestor window if focused window is
invisible.
This patch makes nsFocusManager::GetFocusedDescendant() can return only visible
descendants. However, it already has a bool argument. Therefore, it should
have a flag instead of adding new flag. Most changes of this patch is replacing
its callers.
Then, nsRootWindow::GetControllerForCommand() and nsRootWindow::GetControllers()
should have a bool flag if it should return controller(s) for visible window.
This patch adds a bool flag for it. Fortunately, the interface isn't scriptable.
Finally, this patch makes nsXBLPrototypeHandler::DispatchXBLCommand() and
EventStateManager::DoContentCommandEvent() retrieve controller for visible
window since they are always handles user input.

Going through the extension policy service rather than using
WebExtensionPolicy objects directly adds a lot of unnecessary overhead to
common operations on extension principals, and also makes the code more
complicated than it needs to be.
We also use weak references to policy objects here, since principals should
ideally lose as much of their elevated privileges as possible once the
extension instance that created them has been destroyed (which is something we
couldn't handle easily when we simply tracked ID strings).
