function_template_util  <-- Can we give this a snappier name?  Maybe I'm
prejudiced against names with "util"...  How about function_template.h ?

Done.

Yeah I always struggle with naming with C++ templates, because they tend to not
be object-oriented. Naming suggestions throughout welcome.

+WrapperInfo CallbackHolderBase::kWrapperInfo = { kEmbedderNativeGin };

+void CallbackHolderBase::Register(v8::Isolate* isolate) {

EnsureRegistered?  Who's job is it to call this function?  Maybe we should call
it in gin.cc since almost every embedder is going to need it.

+  PerIsolateData* data = PerIsolateData::From(isolate);
+  if (!data->GetObjectTemplate(&kWrapperInfo).IsEmpty())
+    return;
+  v8::Handle<v8::ObjectTemplate> templ(v8::ObjectTemplate::New());
+  templ->SetInternalFieldCount(kNumberOfInternalFields);
+  data->SetObjectTemplate(&kWrapperInfo, templ);
+}
+
+WrapperInfo* CallbackHolderBase::GetWrapperInfo() {
+  return &kWrapperInfo;
+}
+
+}  // namespace gin
