Add the ability to randomize parts of dirty_log_perf_test, specifically the order pages are accessed and whether pages are read or written. v7: Encapsulate the random state inside a struct. Add detail to names of those functions. Change interface so random function returns the next random number rather than using an out parameter. Rebased to kvm/queue to ensure freshness.
