Move a Connection into Another Socket

Demonstrates Socket.TakeConnection, which moves the active connection from one Socket into another. The receiving object first releases any connection it previously held.

Background. Unlike TakeSocket, TakeConnection does not add a member to a socket set. After success, the source socket holds no connection. This is useful for handing an accepted connection to a dedicated handler object.
