With the advent of global and per-schedule signals which use variadic templates, we can retire our use of SIGC++ entirely by storing the callback pointers in the signal objects and invoking them directly rather than by delegating to SIGC++. Since we do not use SIGC++'s abilities to connect signals to each other this should be quite a simple operation, and result in the removal of a layer of indirection and the need to build and distribute the SIGC++ package.
