Connecting to a Raspberry Pi through a VPS using a reverse SSH tunnel

SSH (Secure Shell) to a host existing in an internal network through a reverse-tunneled SSH connection to an externally accessible VPS (Virtual Private Server). This setup is described where the internal host is a Raspberry Pi, but can be generalized for any host on the internal network that runs an OpenSSH server.
