Unforgeable attributes are defined directly on the object, not on the
prototype. So we keep them in a separate spec array and define them
during object creation as needed.
This means that we have to pass that separate spec array to the Xray
helpers, unfortunately, which somewhat complicates those.
We mark constructors as static in the parser because they are. This
allows us to just use the isStatic() for the IDLMember to mark our
declarations static.
To generate an example interface implementation, just "make
interfacename-example" in $objdir/dom/bindings. This will place files
called interfacename-example.h and interfacename-example.cpp in that
directory. For example, "make XMLHttpRequest-example" will get you
$objdir/dom/bindings/XMLHttpRequest-example.h and
$objdir/dom/bindings/XMLHttpRequest-example.cpp.
Attribute getters currently default to const methods, while setters
and operations default to non-const methods.
The new setup is:
* Consequential interfaces with no explicit descriptor are still skipped.
* If no information is provided about an interface, an empty descriptor is
assumed.
* If a list is provided and the only entry is a worker descriptor, an empty
main-thread descriptor is assumed.
There are several parts here:
1) Enforce the requirement that dictionary arguments not followed by a required argument are optional.
2) Make dictionaries no longer be distinguishable from nullable types.
3) Disallow dictionaries or unions containing dictionaries inside a nullable type.
4) Force optional dictionaries to have a default value of null so that codegen doesn't have to worry about dealing with
optional arguments that have no default value in the IDL but need to be treated as if they were null.

In this new setup, there are three new extended attributes: Infallible,
GetterInfallible, SetterInfallible. The first one applies to both methods and
attributes, while the last two apply only to attributes. Each one can be
either set with no value specified (in which case it applies both on main
thread and in workers) or can be set to MainThread or Workers to limit where it
applies.
If Infallible is set on an attribute, then GetterInfallible and
SetterInfallible will be ignored. So if you want to specify, for example, an
attribute that's infallible on the main thread and has an infallible getter in
workers, the right way to do that is [GetterInfallible,
SetterInfallible=MainThread].
