Add support for runtime log compression

If log_compression=64M is specified, fio will "bite" off chunks of
the IO logs and runtime compress them with zlib. This can greatly
reduce the amount of memory required to do iops/bw/lat logging of
a run, at the cost of using some background CPU for the compression.
