WIP Unify error codes returned to the connection handler

Browse Source 
Error argument in the connection handler is not always set and in some
cases provides meaningless values. For example, every TLS module returns
its specific error codes.

Current solution unifies error codes and allows to distinguish between
different types of disconnection.

Fixes #123.
