After recent refinement of LUN hotplug, it is possible that
for large write I/O, primary task is freed doubly as a github issue
is reported.
However we could not notice the case because spdk_del_transfer_task()
had not return success/failure, and to make matters worse,
the second call of TAILQ_REMOVE() to the same header and instance
caused no error if the first call succeeded.
This patch changes spdk_del_transfer_task() to return success/failure.
Besides, the next after patch expects the stub of spdk_del_transfer_task()
returns true in the unit test, and hence do that.
The next after patch will fix the issue of double free of primary task
by using this patch.

By the recent refactoring, SCSI task is configured when getting
DIF context from SCSI layer. Passing not CDB and offset separately
but SCSI task to SCSI layer is more concise and do in this patch.
In iscsi_send_datain(), we have to update task->scsi.offset for the
case that data is split into a sequence, but the update is no harm
because task has completed what it must to do.

iSCSI target frees iSCSI tasks when exiting connection or removing

tasks from iscsi_conn_free_tasks() and _iscsi_conn_remove_lun()

This patch binds poll groups to SPDK thread through IO channel and
assigns connections to poll groups instead of cores.
iSCSI subsystem registers iSCSI global object as an IO device, and create
poll groups as context of IO channels of the IO device.
Each portal get and hold portal group on which the corresponding acceptor is
running.
When a connection is constructed, iSCSI subsystem assigns a poll group
to the connection by getting it from the corresponding portal.
When a connection enters full-feature phase, iSCSI subsystem schedules
the connection to a poll group by round-robin.
Then, each connection can know its running SPDK thread directly and can
use SPDK message passing infrastructure instead of SPDK event framework.
By this change, iSCSI connections are binded to SPDK thread, and not
binded to processor core anymore.
Some other changes in this patch are
- core ID is removed from the output of get_iscsi_connections RPC. The
upcoming patches will change the RPC to use spdk_for_each_channel and can
access SPDK thread safely, and add SPDK thread ID instead.
- utilize UT multithread framework added by the last patch to test
iSCSI poll groups by UT.

The next patch will add the function ponter typedef
spdk_scsi_dev_destruct_cb for SCSI device destruction.
Hence add lun to the names of descriptors and callback for SCSI
LUN for clarification.
This patch doesn't change any behavior.

When any iSCSI target is destructed, if the target exits all corresponding
connections first, destructing SCSI device will be easier.
Hence, iscsi_tgt_node_destruct() starts exiting all corresponding
connections. Then it destructs SCSI device immediately if no active
active connections, or waits for the completion if there is any
active connection for the target.

Add the flag destructed to struct spdk_iscsi_tgt_node and
iscsi_op_login_check_target() refers it and returns
ISCSI_LOGIN_TARGET_REMOVED if it is true.
When destructing iSCSI target node, it will be nice if iSCSI library
can stop further connections are created but, connections are not
associated with any target node until processing login. Hence stop
creating sessions instead.
Additionally, when destructing iSCSI target node, if the flag destructed
is already set, return immediately, and the flag destructed does not
affect discovery session.

LUN ID is not converted from integer to structure and integer is
set to R2T PDUs.
Popular iSCSI initiators don't check this value and work correctly.
This patch uses the public helper function of the SCSI library
to fix the issue.
Additionally, private helper function to convert structure to
integer for LUN ID is replaced to the public helper function
of the SCSI library.

iSCSI library had used the prefix spdk_ for most functions regardless
of private or public. Using the prefix spdk_ only for public functions
will be helpful to distinguish private and public functions, and
will be helpful to investigate issues or do further improvement.
Besides in iscsi.c static variable spdk_arc4random_initialized had
the prefix spdk_, and change it to g_arc4random_initialized according
to the SPDK's good practice.
iSCSI library still have some issues but is more stable than before
and now will be the good time to adjust the naming rule to other
libraries.
This patch doesn't change any behavior.

Upcoming patches will support DIF insert and strip feature in
iSCSI target and the feature will be implemented by utilizing
iovecs.
Even when we support the DIF feature, we want to keep current
batched PDU flush, and current requirement that there must be
enough free iovecs to map all segments of a PDU is too strict.
This patch alleviates the requirement by passing remaining
number of iovecs to spdk_iscsi_build_iovs().
