Add pthread barrier support.
Implementation and documentation for:
- pthread_barrier_init()
- pthread_barrier_destroy()
- pthread_barrier_wait()
- pthread_barrierattr_init()
- pthread_barrierattr_destroy()
- pthread_barrierattr_getpshared()
- pthread_barrierattr_setpshared()
Currently only private barriers are supported.
Okay guenther@.
