* include/ut0mem.h, os/os0proc.c, ut/ut0mem.c:
Protect ut_total_allocated_memory with ut_list_mutex in
os_mem_alloc_large() and os_mem_free_large(). The lack of this
mutex protection could cause an assertion failure during fast
index creation. Also, add UNIV_MEM_ALLOC and UNIV_MEM_FREE
instrumentation to os_mem_alloc_large() and os_mem_free_large(),
so that Valgrind can detect more errors.

Make innodb_thread_concurrency=0 the default. The old default
value was 8. A non-zero setting may be useful when InnoDB is
showing severe scalability problems under multiple concurrent
connections.

Clean up the insert buffer subsystem so that only one insert
buffer B-tree exists.
Originally, there were provisions in InnoDB for multiple insert
buffer B-trees, apparently one for each tablespace.
When Heikki Tuuri implemented multiple InnoDB tablespaces in
MySQL/InnoDB 4.1, he made the insert buffer live only in the
system tablespace (space 0) but left the provisions in the code.
