marko 0011a8a91a Reduce buffer pool mutex contention under >= 4 big concurrent
CPU-bound SELECT queries.  (Bug #15815)

Fix: replace the mutex by one mutex protecting the 'flush list'
(and the free list) and several mutexes protecting portions of the
buffer pool, where we keep several indivudual LRU lists of pages.

This patch is from Sunny Bains and Heikki Tuuri.
