Currently, each histogram range is hardcoded to
128 buckets (1ULL << 7), resulting in 58 ranges
(64 - 7 + 1) and a total size of 58 * 128 *
sizeof(uint64_t) = 59392 bytes.
To allow for more usage models in cases where this
size is prohibitive, enable the following changes:
1) specify number of buckets per range (in number of bits)
2) specify max datapoint value (in number of bits)
The latter can be useful for cases where datapoints
are never close to requiring all 64 bits - and allows
reducing the number of ranges. Any data points that
exceed the max will be tallied in the last bucket
in the last range.
Testing shows no performance disadvantage using the
dynamic approach.

being a series of jobs in the same fio config file. If we
don't do this and subsequent jobs are specifying a higher queue
depth than earlier jobs, the NVMe qpairs will be too small and
performance results can be way off.
Future fix logged on Trello to correctly size q pairs even when
multiple jobs are specified in a single file but this is a small
optimization.

fio has a race between reap_threads() and free_ioengine(). free_ioengine()
will call the ioengine's cleanup routine and then dlclose it if it
is dynamically linked (like the spdk fio plugin). free_ioengine() does
not set td->io_ops = NULL though until after dlclose() is complete. If
reap_threads() tries to dereference td->io_ops after our plugin has been
closed but before io_ops was set to NULL, it will segfault.
Solution (until an upstream fio fix is available) is to use LD_PRELOAD
instead.

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.

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().

This patch also drops support for automatically unbinding
devices from the kernel - run scripts/setup.sh first.
Our generic pci interface is now hidden behind include/spdk/pci.h
and implemented in lib/util/pci.c. We no longer wrap the calls
in nvme_impl.h or ioat_impl.h. The implementation now only uses
DPDK and the libpciaccess dependency has been removed. If using
a version of DPDK earlier than 16.07, enumerating devices
by class code isn't available and only Intel SSDs will be
discovered. DPDK 16.07 adds enumeration by class code and all
NVMe devices will be correctly discovered.

spdk_nvme_ctrlr_cmd_get_log_page() now allocates a physically contiguous
buffer internally, so the caller does not need to provide special
DPDK-allocated memory.

Now that the NVMe library handles physically contiguous buffer
allocation for reservation functions, the example can just use normal
local variables.

After the NVMe library API change to perform user copies, we don't need
to pass rte_malloc() memory to the NVMe controller utility functions
like spdk_nvme_ctrlr_cmd_get_log_page().
Use regular global variables to simplify the identify example code.
At the same time, fix the code that retrieves error log pages -
previously, it was allocating space for multiple error log entries, but
it was only passing the size of a single entry to the Get Log Page
command. Now we preallocate the worst-case array size: ELPE, which
indicates the maximum number of error log page entries, is a single
byte, and it is 0's based, so the largest possible array is just 256
entries.

The previous method for registering I/O queues did not allow the user
to specify queue priority for weighted round robin arbitration, and it
limited the application to one queue per controller per thread.
Change the API to require explicit allocation of each queue for each
controller using the new function spdk_nvme_ctrlr_alloc_io_qpair().
Each function that submits a command on an I/O queue now takes an
explicit qpair parameter rather than implicitly using the thread-local
queue.
This also allows the application to allocate different numbers of
threads per controller; previously, the number of queues was capped at
the smallest value supported by any attached controller.
Weighted round robin arbitration is not supported yet; additional
changes to the controller startup process are required to enable
alternate arbitration methods.
