service_read ()
Used to read from a session. Handles scheduling
if the session would block.
Used for reading from a service thread. If the read would block,
put the thread to wait. When the scheduling cycle sees input on this
session the random_input_ready_action is called.
This wakes up this thread and schedules it for execution on the next
round
The need_all argument controls whether this function may return after reading
fewer than the requested number of bytes. This function always reads at
least 1 byte.
If the calling thread is the scheduling thread and io would block, this
allows schedule and recursively blocks on all pending i/o.
If the calling thread is some other thread, this disables
the thread and tells the scheduler to resume this when the input is ready.
Returns the number of bytes read.
