Many open source projects have moved to using SPDX identifiers
to specify license information, reducing the amount of
boilerplate code in every source file. This patch replaces
the bulk of SPDK .c, .cpp and Makefiles with the BSD-3-Clause
identifier.
Almost all of these files share the exact same license text,
and this patch only modifies the files that contain the
most common license text. There can be slight variations
because the third clause contains company names - most say
"Intel Corporation", but there are instances for Nvidia,
Samsung, Eideticom and even "the copyright holder".
Used a bash script to automate replacement of the license text
with SPDX identifier which is checked into scripts/spdx.sh.

Previously free connections had been managed by g_conns_array,
and allocate_conn() gets the lowest free connection. This had worked
almost as LIFO, and the just freed connection had been reused
immediately to the new connection.
Using TAILQ makes management of free connections FIFO, and this will
be more intuitive and simpler, and avoid potential issues due to the
fact that we do not know the state INVALID is the current connection
or the current connection is exited and the new connection is allocated.
This patch includes following updates.
Remove the test condition that the connection ID should be zero.
Connection ID is used as Target Transfer Tag (TTT) and TTT is opaque
number. Hence requiring connection ID to be zero is not meaningful.
iscsi_conn_free() calls free_conn() while holding g_conns_mutex, but
iscsi_conn_construct() does not call free_conn() without holding
g_conns_mutex. Hence add g_conns_mutex to the latter.

We ensure current pending tasks are aborted and no new task or PDU

task completions and aborts are sent to initiator.
However, we had removed pending tasks without any notification to
initiator. For this implementation, we are not surprised if initiator
waits for in-flight commands for a long time.
Due to recent refinements of LUN hotplug, we can wait safely that
all existing tasks complete or abort.
In _iscsi_conn_hotremove_lun(), after aborting R2Ts, start a poller
to wait until all PDUs for the LUN are flushed. Then close the LUN.
We can safely free deferred PDUs for the LUN because they are
already flushed.

Previously we had allocated temporary context, struct
_iscsi_conn_remove_ctx to process LUN hotplug. However, we
had to consider out of memory during connection is active,
and we could not use any poller to process LUN hotplug because
LUN hotplug may conflict with connection exit, and this
possible conflict made us very difficult to use poller for LUN
hotplug. Introducing struct spdk_iscsi_lun will resolve all
these issues.
Allocate struct spdk_iscsi_lun per LUN and store connection,
LUN, and LUN's descriptor into the struct. Then use the struct
for LUN hotplug and free the struct after LUN is closed when
LUN is removed or connection exits.
struct spdk_iscsi_lun is similar with struct spdk_nvmf_ns in

Previously require_chap, disable_chap, and mutual_chap had been set

and used in iscsi_get_authinfo().
If a connection is in a discovery session, the connection can get

If a connection is in a normal session, the connection can get all
CHAP params in iscsi_op_login_negotiate_chap_param().
Each connection is in either discovery session or normal session.
So the following change is possible and is done in this patch.
spdk_iscsi_conn_construct() sets all CHAP params of the connection
by global parameters. Then iscsi_op_login_negotiate_chap_param()
overwrites them by the corresponding target's parameters.
iscsi_negotiate_chap_param() and iscsi_get_authinfo() just refer

Besides, iscsi_get_authinfo() changed to call just
spdk_iscsi_chap_get_authinfo() inside, and so inline
spdk_iscsi_chap_get_authinfo() into iscsi_auth_params() and then
remove iscsi_get_authinfo().

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 following changes are added in this patch:
1. Remove unused TRACE_ISCSI_CONN_ACTIVE and TRACE_ISCSI_CONN_IDLE.
2. TRACE_ISCSI_TASK_EXECUTED is added. This tracepoint can be used
to record TSC for every PDU, especially non-SCSI PDU.
3. TRACE_ISCSI_PDU_COMPLETED is added. This tracepoint is for SCSI PDU.
It will record the TSC which includes the cycles of flushing writebuf.

When hot removal of a LUN is started, callback is called for each
iSCSI connection which accesses the LUN. Callback checks all transfer
tasks complete and then close the LUN.
If the connection clears all transfer tasks before getting all responses
to them from the initiator, the initiator continues to retry data write.
Hence the connection have to wait until all transfer tasks complete.

Reason: If we trigger the spdk_iscsi_conn_migration,
we may face the issue that the io channel of lun
is NULL(which means not allocated). So I think
that if we trigger the migration, we need to
stop the executing the further pdu of this conn
by the current polling group.
Also since the connection is triggered migration,
we should stop execution on the current core, and
let this connection be handled by next round.

This provides an abstraction layer around TCP
sockets. Previously we just used fd integers, but
we don't want to be tied to integers for alternative
userspace TCP stacks.
Future patches will do more work to enable multiple
implementations of this abstraction. For now, just
get the abstraction in place for POSIX sockets and
make all of the iSCSI changes associated with it.

Fixes github issue #218.
This patch introduces spdk_cpuset object to store and manipulate
the set of individual CPUs. The main objective of this object is
to replace cpumask declared as uint64_t and extend the limitation
of supported CPUs (lcores) above 64 CPUs.
spdk_cpuset is always allocated dynamically and accessed by opaque
pointer, what makes it easier to extend in the future without
breaking API/ABI.
This patch also extends parsing function allowing to set cpumask
using a list of cpus e.g. "[0-4,10,12]" sets mask of 0,1,2,3,4,10,12
as well as hexadecimal string with and without "0x" prefix.
