This patch introduces wrappers for accessing in/out streams indirectly.
This will enable to replace physically contiguous memory arrays
of streams with flexible arrays (or maybe any other appropriate
mechanism) which do memory allocation on a per-page basis.

v2 changes:
 sctp_stream_in() users are updated to provide stream as an argument,
 sctp_stream_{in,out}_ptr() are now just sctp_stream_{in,out}().

...

 
 struct sctp_stream {
-	struct sctp_stream_out *out;
-	struct sctp_stream_in *in;
+	struct flex_array *out;
+	struct flex_array *in;

If this patch was meant to be a preparation, shouldn't this belong to
the next patch instead?
