Python udp broadcast client-server example (previously)

Works for python 3.7 and 2.7 for Mac OS and Linux(kernel>=3.9) hosts. If you're using linux(kernel<3.9), then use socket.O_REUSEADDR instead of socket.SO_REUSEPORT to share (host, port) between multiple clients and servers.

Tricks and traps:

• Socket portability issues: How do SO_REUSEADDR and SO_REUSEPORT differ?;
• Awesome "Socket Programming HOWTO";
