        * birnetthread.hh: provide read and write memory barriers:
        Atomic::read_barrier(), Atomic::write_barrier().
        Atomic::RingBuffer: prevent class copies, fixed destructor, use
        std::copy() for fast memory copies and added missing barriers;
        fixes suggested by Stefan Westerfeld.

        * tests/threads.cc: fixed contention handling in ring buffer tests.
