libsigc++ 2.99.5: Even less code

I managed to rip out another chunk of slightly-incomprehensible code from libsigc++, and those improvements are in libsigc++-3.0’s 2.99.5 version.

Now there’s no common functor_base base class and I removed all those interdependent result_type typedefs that were scattered throughout the code. When I had unravelled the whole result_type chain, I could replace it with just a handful of decltype(auto) uses, realising that that’s what the whole mess was trying to achieve. I love decltype(auto).
