By subsequent patches for iSCSI, spdk_scsi_dev_queue_mgmt_task()
will not be called directly from the function that knows TMF code,
and currently setting TMF code to SCSI task is done in
spdk_scsi_dev_queue_mgmt_task().
Hence after subsequent patches for iSCSI, to hand off TMF code to
SCSI task, any dynamic context will be required.
To avoid the dynamic context, extract setting TMF code from
spdk_scsi_dev_queue_mgmt_task() and put appropriate place for
each call of spdk_scsi_dev_queue_mgmt_task().
Additionally, in spdk_abort_transfer_task_in_task_mgmt_resp(),
ref_task_tag is got from PDU but getting it from SCSI task is
much easier. Hence get ref_task_tag from SCSI task in the callback.

Task management functions don't require performance. Serializing
execution of task managment functions will sipmlify and stabilize
the logic and will be helpful for upcoming patches to support
other task management functions.
This patch introduces two queues, pending and submitted queue,
and serializes LUN reset exection and makes LUN hot removal
wait for LUN reset.
Besides, checking if LUN is NULL is moved to the upper layer as
same as IO task submission.

Instead of silently truncating overly-long SCSI dev names, add an
explicit check and return an error if the name is too long.
Since we now calculate the length of name up front, this also allows
simplification of the copy into dev->name.
This also ensures that dev->name will always be zero-terminated, so we
can simplify the strnlen() in spdk_bdev_scsi_pad_scsi_name() to a
strlen() and remove the invalid unit test case for padding names longer
than SPDK_SCSI_DEV_MAX_NAME.

Removing an LUN from an existing iSCSI target is possible by
removing the corresponding BDEV. However adding an LUN to an
existing iSCSI target is not possible yet.
Add a new function spdk_iscsi_tgt_node_add_lun() and related
functions first toward supporting this function.
JSON-RPC for this operation will be submitted an another patch.
Informing the newly added LUN to the initiator is not included
in this patch. Hence this operation is possible only for any
inactive target.

bdev hotremove event is send directly to hotremove callback given
during spdk_scsi_dev_construct() call. So any bdev hotremove might be
promoted to whole SCSI device removal (like in vhost) wich will trigger
LUN removal. But after returning from hotremove callback LUN and device
might be still referenced (eg to register poller or by outstanding IO).
Even worse: spdk_scsi_dev object is not dynamicaly allocated but
returned from static array which mean there is no way to detect
use-after-free error on spdk_scsi_dev by any tool. This might lead to
using SCSI device that is freed or assigned to different device.
To fix this:
- always delete LUN using hotremove path
- defer spdk_scsi_dev delete/removal after all LUNS are really
deleted.

There is no need to keep a lun name anymore - we always
use the bdev name as the lun name so it is not providing any
additional value. This also keeps us from associating
the same bdev with different LUNs on different iSCSI target
nodes or vhost-scsi controllers.
Side effect of this change is:
1) Use "bdev_name" across the APIs to make it more clear
what these names refer to.

spdk_scsi_lun_construct() and _destruct() in the UT code will

However, the current code was assuming that LUN 0 had to be in the first

with the scripts/rpc.py implementation that uses a Python (unordered)
dictionary object to generate the lun_ids array, there could be cases
where LUN 0 exists in the list but isn't first.
Fix the check by allowing LUN 0 in any position of the lun_id_list
array.
