[MAJOR] make stream sockets aware of the stream interface
As of now, a stream socket does not directly wake up the task
but it does contact the stream interface which itself knows the
task. This allows us to perform a few cleanups upon errors and
shutdowns, which reduces the number of calls to data_update()
from 8 per session to 2 per session, and make all the functions
called in the process_session() loop completely swappable.
Some improvements are required. We need to provide a shutw()
function on stream interfaces so that one side which closes
its read part on an empty buffer can propagate the close to
the remote side.
