(Deprecated:
          Use make_service().) Add a service object to the execution_context.
        
template<
    typename Service>
friend void add_service(
    execution_context & e,
    Service * svc);
          This function is used to add a service to the execution_context.
        
                The execution_context
                object that owns the service.
              
                The service object. On success, ownership of the service object is
                transferred to the execution_context.
                When the execution_context
                object is destroyed, it will destroy the service object by performing:
delete static_cast<execution_context::service*>(svc)
                Thrown if a service of the given type is already present in the
                execution_context.
              
                Thrown if the service's owning execution_context
                is not the execution_context
                object specified by the e parameter.
