Implement co-operative script termination if termination comes during a script wait event (llSleep(), etc.)
This makes use of EventWaitHandles since various web references indicate that Thread.Interrupt() can also cause runtime instability. If co-op termination is enabled, then termination sets the wait handle instead of waiting for a timeout before possibly aborting the thread. This allows the script to cleanly terminate if it's in a llSleep/LL function delay or the next time it enters such a wait without any timeout period. Co-op termination is not yet testable since checking for termination request within loops that never trigger a wait is not yet implemented. This commit, unlike 1b5c41c, passes the wait handle as an extra parameter through IScript.Initialize() instead of passing IScriptInstance itself.
