define stream_security_context_t as a struct to get type checking

Browse Source 
By using a struct we may have warnings at compilation time in some
cases if the type is not used properly.

The type definition becomes a bit weird, so we need to properly
comment.

If too strange, we can revert to the classical "void" definition.
