lib: Use PTHREAD_COND_CLOCK for blocking reads0.10.6

The rbuff uses the PTHREAD_COND_CLOCK for its condition variables, but
the flow_read was passing a time it got from the CLOCK_REALTIME_COARSE
clock. This causes the blocking reads not to timeout correctly.

The oping was updated to detect server timeouts and finish gracefully.
