MEDIUM: stconn: Check room needed to unblock opposite SC when data was sent

Browse Source 
After a sending attempt, we check the opposite SC to see if it is waiting
for a minimum free space to receive more data. If the condition is
respected, it is unblocked. 0 is special case where the SC is
unconditionally unblocked.
