Safepoint protocol upgrade

Upgrade to the new stop-the-world protocol from the Windows branch,
dating back to late 2011, an all-in-one readability and correctness
improvement.

Replace per-thread qrl locks with one process-wide lock for all
operations relating to GC state and the threads' CSP area.  Use
condition variables for notifications on GC state changes.

Thanks to Anton Kovalenko.
