MINOR: stream: Add a pointer to set the parent stream

Browse Source 
A pointer to a parent stream was added in the stream structure. For now,
this pointer is never set, but the idea is to have an access to a stream
environment from another one from the moment there is a parent/child
relationship betwee these streams.

Concretely, for now, there is nothing to formalize this relationship.
