MINOR: stream-interface: introduce si_reset() and si_set_state()
The first function is used to (re)initialize a stream interface and
the second to force it into a known state. These are intended for
cleaning up the stream interface initialization code in session.c
and peers.c and avoiding future issues with missing initializations.
