Switch from using the interface objects from the Xrays compartment to wrapping
interface objects and interface prototype objects in Xrays. Make dom binding
Xrays deal with both instance objects and interface and interface prototype
objects.
For new DOM proxies, we could probably use the Xray expando machinery for the
regular expando object as well, and free up one of the reserved slots. That's
more than I want to bite off for the moment, though.
I also decided not to block on bug 760095 and just kick the problem of globals
with new binding down the road a little bit.
ErrorResult is in a separate header file so it can be included from all over the
place without having to pull in mozilla/dom/Utils.h and all the xpconnect gunk
that needs.

In the new setup, all per-interface DOM binding files are exported into
mozilla/dom. General files not specific to an interface are also exported into
mozilla/dom.
In terms of namespaces, most things now live in mozilla::dom. Each interface
Foo that has generated code has a mozilla::dom::FooBinding namespace for said
generated code (and possibly a mozilla::bindings::FooBinding_workers if there's
separate codegen for workers).
IDL enums are a bit weird: since the name of the enum and the names of its
entries all end up in the same namespace, we still generate a C++ namespace
with the name of the IDL enum type with "Values" appended to it, with a
::valuelist inside for the actual C++ enum. We then typedef
EnumFooValues::valuelist to EnumFoo. That makes it a bit more difficult to
refer to the values, but means that values from different enums don't collide
with each other.
The enums with the proto and constructor IDs in them now live under the
mozilla::dom::prototypes and mozilla::dom::constructors namespaces respectively.
Again, this lets us deal sanely with the whole "enum value names are flattened
into the namespace the enum is in" deal.
The main benefit of this setup (and the reason "Binding" got appended to the
per-interface namespaces) is that this way "using mozilla::dom" should Just
Work for consumers and still allow C++ code to sanely use the IDL interface
names for concrete classes, which is fairly desirable.

Pass two objects when creating a DOM interface object, the global used to cache
the DOM interface objects and a receiver object on which the named property is
that points to the DOM interface object.

This part changes the signatures for various finalization API to take
not JSContext* but rather either JSFreeOp structure or its
library-private counterpart FreeOp. These structures wrap parameters
that are passed to the finalizers removing most of explicit dependencies
on JSContext in the finalization code.
Currently the GC finalizes on the background thread only objects with null
JSClass::finalize. However, this implies that any object that uses
JS_FinalizeStub for the finalizer would be prevented from the background
finalization.
To fix this the patch removes JS_FinalizeStub replacing it with NULL in all
cases when the class has no custom finalizer. For style consistency the patch
also removed the usage of JSCLASS_NO_OPTIONAL_MEMBERS in the static
declarations as the compiler fills the missing fields with null in any cases.
