Careful SMP locking - Fix very occasional hangs Louis Zulli reported that Stockfish suffers from very occasional hangs with his 20 cores machine. Careful SMP debugging revealed that this was caused by "a ghost split point slave", where thread was marked as a split point slave, but wasn't actually working on it. The only logical explanation for this was double booking, where due to SMP race, the same thread is booked for two different split points simultaneously. Due to very intermittent nature of the problem, we can't say exactly how this happens. The current handling of Thread specific variables is risky though. Volatile variables are in some cases changed without spinlock being hold. In this case standard doesn't give us any kind of guarantees about how the updated values are propagated to other threads. We resolve the situation by enforcing very strict locking rules: - Values for key thread variables (splitPointsSize, activeSplitPoint, searching) can only be changed when the thread specific spinlock is held. - Structural changes for splitPoints[] are only allowed when the thread specific spinlock is held. - Thread booking decisions (per split point) can only be done when the thread specific spinlock is held. With these changes hangs didn't occur anymore during 2 days torture testing on Zulli's machine. We probably have a slight performance penalty in SMP mode due to more locking. STC (7 threads): ELO: -1.00 +-2.2 (95%) LOS: 18.4% Total: 30000 W: 4538 L: 4624 D: 20838 However stability is worth more than 1-2 ELO points in this case. No functional change Resolves #422
