Add the ability to randomize parts of dirty_log_perf_test,
specifically the order pages are accessed and whether pages are read
or written.
v4:
Ensure all randomization is off for the populate phase (write_percent
= 100 and random_access = false).
Move random number generator to test_util.{c,h} and rename to
guest_random. Make it destructively modify its argument to cover the
most common (probably only) use case.
Make the perf_test_set* functions more efficient by only syncing the
field they change.
Improve style and consistency.
