* split out share/ package into multiple subpackages * added share/compat.go to keep backward compatibility(ish) * moved shared tunnelling logic from client/server packages into share/tunnel/ * added remote protocol "<host>:<port>/<protocol>", currently supporting tcp and udp * added an end-to-end test suite * added TODO e2e tests as contribution targets * added deep context integration for improved cleanup and cancellation

Performance
With crowbar, a connection is tunneled by repeatedly querying the server with updates. This results in a large amount of HTTP and TCP connection overhead. Chisel overcomes this using WebSockets combined with crypto/ssh to create hundreds of logical connections, resulting in one TCP connection per client.
In this simple benchmark, we have:
