While working on the changes required to make the health checks use the new connections, it started to become obvious that some naming was not logical at all in the connections. Specifically, it is not logical to call the "data layer" the layer which is in charge for all the handshake and which does not yet provide a data layer once established until a session has allocated all the required buffers. In fact, it's more a transport layer, which makes much more sense. The transport layer offers a medium on which data can transit, and it offers the functions to move these data when the upper layer requests this. And it is the upper layer which iterates over the transport layer's functions to move data which should be called the data layer. The use case where it's obvious is with embryonic sessions : an incoming SSL connection is accepted. Only the connection is allocated, not the buffers nor stream interface, etc... The connection handles the SSL handshake by itself. Once this handshake is complete, we can't use the data functions because the buffers and stream interface are not there yet. Hence we have to first call a specific function to complete the session initialization, after which we'll be able to use the data functions. This clearly proves that SSL here is only a transport layer and that the stream interface constitutes the data layer. A similar change will be performed to rename app_cb => data, but the two could not be in the same commit for obvious reasons.
