Tokio Stability

• No functional change
• Update from Tokio 0.3 to 1.0.
• Add some quickcheck tests to validate PeerAddr and retain_unordered

Going Green

• Restructure connection handling to reduce memory and CPU use
• Observed drop of ~2MB from 8MB to 6MB with 4000 connections
• Remove --threads option, tarssh is now strictly single-threaded
• Send the banner line-by-line
• Track bytes sent per-connection and globally
• Add SIGINFO (and SIGHUP) support to log status on demand
• Stop calling accept() when the connection limit is reached

Moving to NeoTokio

• Update to Tokio 0.3.4
• Set socket buffers on listen rather than after accept
• Remove references to not-really-maintained Docker image
