Fix bug in which we could forget to mark stopping mutators
...
Separately track total mutator count, paused mutators, and inactive
mutators. Paused mutators need to mark their roots before stopping. We
had a bug whereby a paused mutator would not wake up before the next
collection, which resulted in that mutator's roots not being marked.
Fix by resetting paused mutator count to 0 after collection, requiring
those mutators to sync up again.

Rework parallel tracing state machine
...
Instead of sending a message to each worker, we pthread_cond_broadcast
at the start. Instead of having N worker threads, we have N-1 threads
and the main thread also does work. Instead of termination being
detected by the worker threads, let the main thread detect it. Avoid
parallelism if the mark stack is small enough, which can be the case for
ephemeron chains. Let aux threads exit when they have no work instead
of spinning: sharing will start them up again.
