Mostly automatic via sed. Only parts which I touched manually (apart from a
couple ones where I fixed indentation or which had mispelled arguments) are the
callers. I may have removed a couple redundant `virtual` keywords as well when
I started to do it manually, I can revert those if wanted.
Most of them are just removing the argument, but in Element.cpp I also added an
assertion for GetBindingParent when binding the ShadowRoot's kids (the binding
parent is set from the ShadowRoot constructor, and I don't think we bind a
shadow tree during unlink or what not which could cause a behavior difference).

Therefore, I would like to send a new notification when autoplay occurred.

```

Always assume allowed-for-all-content. There are a couple callers which weren't
doing that:
* A unit test -> removed.
* ComputeAnimationDistance: Used for testing (in transitions_per_property), and
for the animation inspector. The animation inspector shouldn't show
non-enabled properties. The transitions_per_property test already relies on
getComputedStyle stuff which only uses eForAllContent.
* GetCSSImageURLs: I added this API for the context menu page and such. It
doesn't rely on non-enabled-everywhere properties, it was only using
eInChrome because it was a ChromeOnly API, but it doesn't really need this.

On the compositor we store animation values in a hash table and the hash is
the compositor animation id which is a unique id for each property respectively.
So we can get the corresponding animation value for the given property.

mozInlineSpellChecker::ReplaceWord() is used for replacing misspelled word
with a word. So, this is necessary to be distinguished from insertText
command when we implement InputEvent.inputType. So, we should make it
use TextEditor::ReplaceTextAsAction() instead (same as autocomplete).
This patch makes TextEditor::ReplaceTextAsAction() take optional argument
to make callers can specify replace range. Then, the range is a spellchecker
selection range if the caller is mozInlineSpellChecker::ReplaceWord().
Prior to this patch, it clones the range for normal selection, but it's
expensive and we may be able to reuse cached range of Selection in this case.
So, this patch makes Selection::AddRangeInternal() checks if given range is
in another Selection and use mCachedRange as far as possible.

Selection caches an nsRange instance for saving re-allocation cost and AddMutationObserver() and RemoveMutationObserver()'s cost when its RemoveAllRangesTemporarily() is called.
Then, the instance is detached from the Selection but still referring editing point. E.g., the only text node in TextEditor when its value is set. Therefore, it'll receive character data change notification and need to check whether the point is still valid with new text. However, the range will be always set new position later, i.e., immediately before going back to a part of Selection. Therefore, even if the point becomes invalid, nobody must not have any problems.
This patch makes Selection make the cached range not positioned, and makes nsRange ignore any mutations when it's not positioned.

* Count of the number of top level content documents which contained (directly
or in a descendant document) playback of an audible media element.
* Count of the number of top level content documents which contained (directly

autoplay policy because it tried to unmute and it wasn't allowed to autoplay
audibly.
* Count of the total number of audible autoplay videos that would have not been
allowed to play if block autoplay was enabled. We'd either prompt for
permission on these videos, or block outright depending on user's settings.

This removes AutoMaybeEnterFrameRealm. Most places pass cx->realm->principals: it preserves behavior when the (possibly wrapped) SavedFrame and cx are same-compartment. The main exception is the JSStackFrame DOM bindings code where we have to be a bit smarter about which principals to use.
The stack object might be a CCW and we want to make it impossible to get a CCW's global. Now the caller has to supply a same-compartment global object, so we no longer rely on getting the CCW's global.
Summary:
This fixes a couple fuzz bugs and prevents special-casing <svg:use> even more in
bug 1431255.
Unfortunately not as many hacks went away as I'd have hoped, since we still need

I also tried to avoid this change but, again, given the number of times I was
repeating the same pattern of defining a static method just to forward a
callback to an instance method, decided it was probably necessary. Without an
easy way to do this, people are more likely to register observers rather than
callbacks, for which we'll wind up paying a continued memory and performance
penalty.
This patch adds a helper which creates a type-safe preference callback
function which forwards calls to an instance method on its closure object.
The implementation is somewhat complicated, mainly due to the constraint that
unregistering a callback requires passing the exact same function pointer that
was used to register it. The patch achieves this by creating the callback
function as a template, with the method pointer as a template parameter. As
long as the Register and Unregister calls happen in the same translation unit,
the same template instance is guaranteed to be used for both.
The main difficulty is that, until C++ 17, there's no way match a value as a
template parameter unless you know its complete type, or can at least compute
its complete type based on earlier template parameters. That means that we
need a macro to extract the type of the method, and construct the template
with the full set of explicit parameters.

I initially tried to avoid this, but decided it was necessary given the number
of times I had to repeat the same pattern of casting a variable to void*, and
then casting it back in a part of code far distant from the original type.
This changes our preference callback registration functions to match the type
of the callback's closure argument to the actual type of the closure pointer
passed, and then casting it to the type of our generic callback function. This
ensures that the callback function always gets an argument of the type it's
actually expecting without adding any additional runtime memory or
QueryInterface overhead for tracking it.

This way we reuse the same machinery everywhere for the content property.
The only difference is that we need to look at the parent style for content
instead of just our style, and at a given index.
Again, this is fine because changing content reframes, so no chance to mess up.
This allows the generated content stuff to not implement nsImageLoadingContent
and all that stuff, nor deal with events, which makes it much simpler IMO.
Now it just tracks an index. We may not even need for it to be an HTML element,
but I've kept that for now.

Key of TextCompositionArrary to search composition on widget is native IME
context. However, if TextInputProcessor dispatches composition events via
TextEventDispatcher, TextEventDispatcher::InitEvent() sets native IME context
of dispatching composition events to pseudo IME context (that's raw pointer
of TextEventDispatcher and process ID).
IMEStateManager::DispatchCompositionEvent() looks for existing TextComposition
with native IME context stored in WidgetCompositionEvent before dispatching
an event. However, after dispatching it, it looks for remaining TextComposition
instance with widget stored in WidgetCompositionEvent. Then,
TextCompositionArrary::IndexOf(nsIWidget*) will look for an instance with
the result of nsIWidget::GetNativeIMEContext() and this never returns actual
native IME context. Therefore, IMEStateManager::DispatchCompositionEvent()
always fails to remove TextComposition instance from the array even after
a test composition is finished.
This patch moves nsIWidget::GetNativeIMEContext() to nsBaseWidget to refer
nsBaseWidget::mTextEventDispatcher makes it return pseudo IME context if
TextInputProcessor has input transaction. Therefore, IMEStateManager becomes
always removes TextComposition from the array when every composition ends.

The front end code can't always guarantee to give us an allow/cancel response
to a permission request. In particular in these cases:
* if we close a tab while showing a doorhanger, or
* if we navigate a tab while showing a doorhanger, or
* if the permission prompt requested in a background tab and never shown.
Handling all of these cases is problematic; we don't get events for all of
these where it's easy and cheap to determine that we should cancel the
permission request.
Canceling the permission request is important in the autoplay-media permission
request case as there's objects waiting on the resolution of the permission
request, and they leak in ASan builds while running chrome tests if the Gecko
size of the permission request doesn't get a notification telling it to stop
waiting.
But we can however rely on the doorhanger code to drop its reference to the
nsIContentPermissionRequest object that we pass to it when the doorhanger goes
away. So we can cancel the permission request in our
nsIContentPermissionRequest's implementation's destructor in order to easily
catch all the above cases.
In order to do that, we need to split AutoplayRequest into two; one part being
the implementation of nsIContentPermissionRequest (AutoplayPermissionRequest),
and the other part being the code to own the PromiseHolder and manage the
permission request (AutoplayPermissionManager).
AutoplayPermissionRequest keeps a weak reference to AutoplayPermissionManager,
so that it can tell the AutoplayPermissionManager to reject the request promise
when it's destroyed.
This fixes the ASan leak for which I got backed out from earlier in this bug,
and also fixes the cases above.
