/**

* Application layered TCP connection API (to be used from TCPIP thread)<br>
* This interface mimics the tcp callback API to the application while preventing
* direct linking (much like virtual functions).
* This way, an application can make use of other application layer protocols
* on top of TCP without knowing the details (e.g. TLS, proxy connection).
