Better control of the IO manager thread; improvements to deadlock checking
In the threaded RTS on *nix platforms:
- we now start the IO manager thread eagerly at startup time
(previously was started on demand).
- we now ask the IO manager thread to stop at shutdown
- In Timer.c:handle_tick, if it looks like we might be in a
deadlock, instead of calling prodOneCapability() which was known to be
wrong, we now send a byte down the IO manager's pipe to wake it up.
This also avoids a case of double-acquisition of a mutex, which
happened if prodOneCapability() was called while the current thread
was holding a mutex.
