Value:

                              void*>::type

CONTRAIL-CUSTOM Helper macros to allow function overloading even when using boost::shared_ptr.

shared_ptr makes overloading really annoying, since shared_ptr defines constructor methods to allow one shared_ptr type to be constructed from any other shared_ptr type. (Even if it would be a compile error to actually try to instantiate the constructor.) These macros add an extra argument to the function to cause it to only be instantiated if a pointer of type T is convertible to a pointer of type U.

THRIFT_OVERLOAD_IF should be used in function declarations. THRIFT_OVERLOAD_IF_DEFN should be used in the function definition, if it is defined separately from where it is declared.
