Support connection to functor with multiple operator()

When variadic templates and decltype are supported, detect the best
overload of operator() to call.
Currently, the code takes the type of the operator(), which requires that
the functor only has one, and that it has no template parameter.

This feature is required if we want to connect to c++1y generic lambda
(N3418)
