5e132b6b7a scsi: Set proper transport protocol id
This patch adds property of transport protocol id to spdk_scsi_dev.
This allows to change it depending on which appliation is using
the device. Previously only iSCSI was used for all.

Setting protocol id is done at the time when device is added to
vhost controller (vhost) or target node (iSCSI).

Please note that for SPDK vhost SAS protocol id is used,
as that is what kernel vhost reports as well.

4b521e1720 app/stub: add a stub application to accelerate startup
Starting SPDK applications can take a long time due to
two factors:  DPDK memory initialization and NVMe
device initialization.

This stub application facilitates eliminating those
delays by leveraging DPDK's multi-process mode.  This
stub application acts as the primary process,
initializing DPDK as well as all NVMe devices bound
to userspace modules (uio/vfio).  Then another
SPDK process can be started using the same instance
ID, which will make that SPDK process a secondary
process of the stub and leverage the DPDK memory and
NVMe device initialization already performed by the
primary process.

To start this will be used to accelerate the iSCSI
system level tests (in test/iscsi_tgt) to significantly
reduce test time in the CI pool.

5f3841f0e3 nvmf: allow NQN to be 223 bytes + null terminator
An ECN to the NVMe 1.3 specification has clarified that the NQN may
contain 223 bytes before the null terminator.  Make all of our NQN
length checks consistently enforce this behavior.

f66a0c9e34 scsi: pass management function as a parameter
Specify the function as a parameter to spdk_scsi_dev_queue_mgmt_task.
This makes the API clearer by making it explicit that the management
function is required for management tasks.

The type of a task is known due to the function used to submit it:
- spdk_scsi_dev_queue_task() for normal SCSI command tasks
- spdk_scsi_dev_queue_mgmt_task() for management tasks

8de75f8107 nvme/perf: add software-based latency tracking
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.
