The latency tracking is done with ranges of bucket arrays.
The bucket for any given I/O is determined solely by TSC
deltas - any translation to microseconds is only done after
the test is finished and statistics are printed.
Each range has a number of buckets determined by a
NUM_BUCKETS_PER_RANGE value which is currently set to 128.
The buckets in ranges 0 and 1 each map to one specific TSC
delta. The buckets in subsequent ranges each map to twice
as many TSC deltas as buckets in the previous range:
Range 0: 1 TSC each - 128 buckets cover deltas 0 to 127
Range 1: 1 TSC each - 128 buckets cover deltas 128 to 255
Range 2: 2 TSC each - 128 buckets cover deltas 256 to 511
Range 3: 4 TSC each - 128 buckets cover deltas 512 to 1023
Range 4: 8 TSC each - 128 buckets cover deltas 1024 to 2047
Range 5: 16 TSC each - 128 buckets cover deltas 2048 to 4095
etc.
While here, change some variable names and usage
messages to differentiate between the existing latency
tracking via vendor-specific NVMe log pages on Intel
NVMe SSDs, and the newly added latency tracking done
in software.

Several examples have a function to associate workers
with threads. Simplify that algorithm.
This seems to just shift some of the complexity
from register_workers down to main, but in the long
run the DPDK threading will get abstracted into
env as well and greatly simplify that part.

The previous implementation tried to maintain a ring buffer of completed
I/O retrieved from ->getevents() that had not yet been retrieved by
->event(), but this is not necessary. None of the other FIO engines
implement this sort of ring buffer, and the only code that calls
->getevents() will always retrieve the full number of events via
->event() afterwards.
Instead, just count how many I/Os have been completed within each
->getevents() call in iocq_count, and reset iocq_count on each new
->getevents().

Since we know the queue depth that we will be using during the test,
request that as the queue size when attaching to NVMe controllers.
Reserve one extra queue entry above the expected queue depth since NVMe
queues must always have one entry free to distinguish between queue

The "idle" status has 2 meanings for IOAT kernel performace
test module dmaperf: performance test task has finished or
no performance task at all. For the lastest kernel(4.8), the
userland tool will get the "idle" status before the kernel
changed to "running", but for some older kernels(3.17,4.0)
the test tool run correctly. So add a sleep syscall before
to get the status will fix it.
