Willy Tarreau 41d3ea521b MEDIUM: ring: unlock the ring's tail earlier
We know we can continue to protect the message area so we can unlock the
tail as soon as we know its new value. Now we're seeing ~6.4M msg/s vs
5.4M previously on 3C6T of a 3rd gen EPYC, and 1.88M vs 1.54M for 24C48T
threads, which is a significant gain!

This requires to carefully write the new head counter before releasing
the writers, and to change the calculation of the work area from
tail..head to tail...new_tail while writing the message.
