[MAJOR] stream_interface: fix the wakeup conditions for embedded iohandlers
Now we stop relying on BF_READ_DONTWAIT, which is unrelated to the
wakeups, and only consider activity to decide whether to wake the task
up instead of considering the other side's activity. It is worth noting
that the local stream interface's flags were not updated consecutively
to a call to chk_snd(), which could possibly result in hung tasks from
time to time. This fix will avoid possible loops and uncaught events.
