Barriers fixed and tested more extensively.
* barrier.c: Fix several bugs in all routines. Now passes tests/barrier5.c which is fairly rigorous. There is still a non-optimal work-around for a race condition between the barrier breeched event signal and event wait. Basically the last (signalling) thread to hit the barrier yields to allow any other threads, which may have lost the race, to complete. tests/ChangeLog: * barrier3.c: Fixed. * barrier4.c: Fixed. * barrier5.c: New; proves that all threads in the group reaching the barrier wait and then resume together. Repeats the test using groups of 1 to 16 threads. Each group of threads must negotiate a large number of barriers (10000). * spin4.c: Fixed. * test.h (error_string): Modified the success (0) value.
