[MEDIUM] stream_interface: make use of buffer_cut_tail() to report errors
The stream_int_return() function used to call buffer_erase() on the response
buffer, which completely wipes it without taking care about whatever could
have been there. Now we more carefully strip only data not scheduled to be
sent.
