Add exit_on_io_done option to the CPU IO engine
The CPU IO engine is most often used to saturate the system,
while running an IO load on it. As such, it's useful to have
CPU engine threads exit automatically, when IO has completed.
Add exit_on_io_done as a CPU IO engine option for that purpose.

iolog: don't serialize the writing of all logs
Serialize based on filename, so that independent logs can be
written at the same time. If the logs are big, this can take
a while to flush to disk. It's silly to have all jobs waiting
on each other, when they could write their own logs independently.

Adds check for numberio during verify phase.
Currently, fio checks the block offset number in a block's header during
the verify phase.
We add a check for the io number (numberio) to detect stale blocks. This
check is performed only on workloads that write data, as those workloads
know what numberio was written to each block.
td->io_issues[ddir] = 0; was removed so that numberio does not get reset
at each iteration; we want numberio to keep incrementing to reflect
how many times the same data was written.

Add options to have fio latency profile a device
This adds three new options:
- latency_target. This defines a specific latency target, in usec.
- latency_window. This defines the period over which fio samples.
- latency_percentile. This defines the percentage of IOs that must
meet the criteria specified by latency_target/latency_window.
With these options set, fio will run the described workload and
vary the queue depth between 1 and iodepth= to find the best
performing spot that meets the criteria specified by the three
options.
A sample job file is also added to demonstrate how to use this.

Fix rate iops with ramp time
When the ramp time is over, fio resets the ->io_issues[]
counters, but not the rwmix counters. This causes a problem
for mixed read/write workloads that are rate limited and
include a ramp time.
Fix it by resetting rwmix_issues with the regular issues.

- Don't track written bytes, just replay the workload by resetting
all the random generators. This should work for any mixture of IO.

- Fixup logging for replay.
