Some basic improvements to the binlog-specific page fifo to hopefully get reasonable scalabitily as a starting point. The fifo is still protected by a global mutex, but some effort is taken to reduce the duration a thread is holding the mutex. Use a cyclic array instead of a linked list so pages can be looked up in constant time. And cache allocated page objects to avoid repeated malloc/free while holding the mutex.
