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.
