Implement generic lock-free queue
The implementation of an ERTS internal, generic, many to one, lock-free
queue for communication between threads. The many to one scenario is
very common in ERTS, so it can be used in a lot of places in the future.
Changing to this queue from a lock based queue, however, often requires
some redesigning. This since we have often used the lock of the queue
to protect other information too.
