Avoids call to CFXJS_Engine::EngineFromIsolateCurrentContext() during the Dispose() path, which feels scary because there aren't guarantees about it having an engine at isolate "dispose" time.

2017-02-27Explicitly tag fxjs native objects.Tom Sepez
Native object callbacks have to distinguish whether the object they have been given is actually a native object and not some ordinary JS object. For method/property calls, this happens via v8's signature mechanism, but signature checks aren't applied to method arguments themselves. Currently, we do this by treating any object with an internal field count of 2 as being such, but this is fragile, and it has been pointed out that other objects with two internal fields are present. Additionally, that the first field points to a structure with a small zero-based object definition ID doesn't really have enough entropy to trust that it isn't some other entity. So add a pointer to an internal address in the second slot to make this safer. Note that we'll also get the same release_assert in the majority of cases as described in the bug. This is great from a security standpoint, but not great from a functional standpoint, except this likely only occurs in the wild if they are trying to mess with us. This just guards the theoretical cases that might pass the existing release_assert.

2017-02-27Fix uninitialized memory read in CJS_Object::GetEmbedObject()Tom Sepez
The expected way to create native PDFium objects for JS is via the NewFxDynamicObject() call in C++, but that doesn't mean that the corresponding constructors won't be called from JS. In that case, the internal fields will be uninitialized, and subsequent method calls may try to use them. Add a constructor callback for all PDFium objects that nulls out these fields (shame that v8 doesn't do this by default, but probably saves some cycles). Then ensure that we check for this possibility in all the places it might turn up. Conversely, if we've just gotten a successful return from NewFxDynamicObject(), we know the CJS_Object/EmbedObj are good, so avoid checking there.
