The codegen changes are mostly a backout of the changes made in bug 1274159.
The HTMLConstructor implementation is mostly copied from one of the
code-generated ones, with a few modifications:
* Derive the interface name from the proto id instead of hardcoding it.
* Use the proto/constructor ids to get constructor and prototype objects.
* Use ErrorResult instead of FastErrorResult; we don't want the precedent of
using FastErrorResult in non-generated code.
There will be further changes to combine HTMLConstructor and
CreateXULOrHTMLElement, in a separate changeset.

This allows custom elements to work in any document in the parent process that
allows XUL and XBL. The test takes the easy option of moving the existing XUL
custom element test to a run with the custom element pref disabled.

This way we don't include it in all the binding headers. We only need
jsfriendapi.h for the static_asserts involving JSJitInfo, so we move those to
PrototypeList.cpp.

KeyframeEffect and KeyframeEffectReadOnly constructors can run in the caller
compartment, which is okay because the current compartment is used in the
following places and all of them are safe:
1. GlobalObject::CallerType(), that is ultimately passed to
nsDocument::IsWebAnimationsEnabled in KeyframeEffectParamsFromUnion,
to decide whether to copy mIterationComposite/mComposite to
KeyframeEffectParams.
GlobalObject::CallerType() can now be different than the target window's one,
if the caller has the system principal and the target is web content, and
in that case nsDocument::IsWebAnimationsEnabled there always returns true
while Web Animations can be disabled on web content.
honoring the mIterationComposite/mComposite properties is OK, since it just
changes the animation behavior, and this is disabled by default until
remaining spec issues are resolved.
2. GlobalObject::Context(), that is ultimately passed to
KeyframeUtils::GetKeyframesFromObject and used while extracting information
from passed-in keyframe object, with iterable/iterator protocols.
Performing that operation in the caller side is okay, since the same thing
can be done on caller, and the operation doesn't perform any GCThing
allocation on the target window global.
KeyframeEffect and KeyframeEffectReadOnly constructors can run in the caller
compartment, which is okay because of the following reasons:
1. The target window global is used for most operation:
* KeyframeEffectReadOnly::ConstructKeyframeEffect uses the target window
global instead of current global.
* KeyframeEffectParamsFromUnion which receives `aGlobal.CallerType()`
In Xray case, Web Animations API can be disabled on web content
(currently disabled on beta/release by default), and in that case some API
won't work even it's triggered from WebExtensions, but it should be fine.
2. GetKeyframesFromObject is executed in the caller's compartment to access
the passed-in JSObject that is keyframe, with iterable/iterator protocols.
This operation doesn't perform any GCThing allocation on the target window
global.
I looked at the diff in the generated code, and the only change is that
SpeechRecognitionEvent's unlink impl goes from:
NS_IMPL_CYCLE_COLLECTION_UNLINK_BEGIN_INHERITED(SpeechRecognitionEvent, Event)
NS_IMPL_CYCLE_COLLECTION_UNLINK(mResults)
tmp->mInterpretation.setUndefined();
NS_IMPL_CYCLE_COLLECTION_UNLINK(mEmma)
NS_IMPL_CYCLE_COLLECTION_UNLINK_END
to:
NS_IMPL_CYCLE_COLLECTION_UNLINK_BEGIN_INHERITED(SpeechRecognitionEvent, Event)
NS_IMPL_CYCLE_COLLECTION_UNLINK(mResults)
NS_IMPL_CYCLE_COLLECTION_UNLINK(mEmma)
+ tmp->mInterpretation.setUndefined();
NS_IMPL_CYCLE_COLLECTION_UNLINK_END

These are cases that are implementing the "convert an exception to a Promise"
steps of the Web IDL spec. Typically the exception is thrown in the current
compartment; the Promise returned should simply match that. Otherwise we can
end up with a situation in which the promise doesn't actaully have access to
its rejection value, which will cause problems if someone uses then() on the
promise: the return value of the then() call will get a sanitized exception
instead of the real one.
We _could_ try to match the actual compartment of the exception, in theory.
But it's not clear why this would be preferable to using the current
compartment, even if there were cases in which the exception _doesn't_ match
the current compartment. Which there likely are not.

We currently don't generate a ::ToJSON() method for WebIDL types with record<K,V>
members. These types should be safe to convert to JSON, as long as type V itself
is. Per spec, type K is always a DOMString, USVString, or ByteString.
As opposed to Alias attribute, which reuses the JS function object for the property, BindingAlias will only reuse the generated attribute binding implementation, without changing observable behavior. It can be used to reduce amount of generated code, if the attributes are known to behave exactly the same.
This cuts the size of generated CSS2PropertiesBinding.cpp by half, and removes ~100kB of dupicated code from libxul.

This restriction was put in place back when we automatically added
QueryInterface to all rootmost non-abstract interfaces. At the time, we needed
to make sure it did NOT end up on EventTarget, because then webidl quickstubs
would replace the QI impl on non-webidl EventTargets with the WebIDL one, which
would not work for them.
Since then, we have removed WebIDL quickstubs and we now explicitly list which
interfaces get QueryInterface, so this check is no longer needed.

When defining WebIDL constants in C++, we may need to undefine some
constant names that conflict with windows.h preprocessor defines.
Doing this in the binding header is far easier than tracking down the
include orders that may cause conflicts.

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.
