Unified callback system based on tr1::function/tr1::bind and Google's internal callback code.
This callback system allows for creation of functors for normal functions, methods, and const methods. It is a superset of the functionality of NewRunnableMethod, NewRunnableFunction, NewCallback, and CreateFunctor.
We support partial binding of function arguments, and also specification of refcounting semantics by wrapping a target object in a wrapper object.

+// The method by which a function is invoked is determined by 3 different
+// dimensions:
+//
+// 1) The type of function (normal, method, const-method)
+// 2) The arity of the function
+// 3) The number of bound parameters.
+//
+// The FunctionTraitsN classes unwrap the function signature type to
+// specialize based on the first two dimensions. The N in FunctionTraitsN
+// specifies the 3rd dimension. We could have specified the unbound parameters
+// via template parameters, but this method looked cleaner.
+//
+// The FunctionTraitsN contains a static DoInvoke() function that is the key to
+// implementing type erasure in the Callback() classes. DoInvoke() is a static
+// function with a fixed signature that is independent of StorageType; its
+// first argument is a pointer to the non-templated common baseclass of
+// StorageType. This lets us store pointer to DoInvoke() in a function pointer
+// that has knowledge of the specific StorageType, and thus no knowledge of the
+// bound function and bound parameter types.
+//
+// As long as we ensure that DoInvoke() is only used with pointers there were
+// upcasted from the correct StorageType, we can be sure that execution is
+// safe.
