Previously we mixed SQ/CQ definition together, one queue pair
data structure may contain CQ,SQ or both CQ and SQ separately,
while here, we split the queue pair definition into SQ and CQ
respectively as code cleanup.
The NVMf library uses queue pair concept, but for vfio-user
case, each SQ created by VM is mapped to NVMf queue pair, so
we also change `connected_qps` to `connected_sqs` to reflect
the fact.
No actual code logic change in this commit.

This patch adds support for using zero-copy operations to execute IO
requests in the TCP transport. Of course, they're only used if the
underlying bdev supports them. Additionally, only requests with no
in-capsule-data can be executed using this mechanism.
Added several new states to accommodate for the difference in a way
zero-copy is handled. Also, these flows very depending on the type of a
request (read or write). It stems from zero-copy semantics: to perform
a write we need to wait for zcopy_end completion, while for reads
zcopy_end can only be submitted once we send all of the requested data
to the host.

Zero-copy requests are kept on the outstanding queue for the whole
duration of the request - from the initial zcopy_start submission to the
completion of zcopy_end. This means, that there's a period in which a
request doesn't wait for a completion from the bdev layer, but is still
on the oustanding queue (after zcopy_start callback, before zcopy_end
submit). If a qpair gets disconnected while a request is in this state,
we need to manually force its completion, as otherwise it might hang
indefinitely (e.g. waiting for host data).

We have very frequent failures when we run test/nvmf/host/multipath.sh
in the test pool.
Call stack showed nvmf_stop_listen_disconnect_qpairs() accessed
qpair->ctrlr even if qpair->ctrlr was NULL.
nvmf_stop_listen_disconnect_qpairs() did not check if qpair->ctrlr is
not NULL before accessing qpair->ctrlr->subsys.
When a qpair is added to a poll group, qpair->ctrlr is cleared to NULL.
The test code test/nvmf/host/multipath.sh executes multiple
reconnects for path error.
So a conflict might occur between adding a qpair to a poll group and
disconnecting a qpair in a poll group.
In this case, it may be acceptable even if we disconnect a qpair whose
qpair->ctrlr is NULL. It will be better than SIGSEGV.
Fixes one of the issues in #2300

The discovery log isn't updated when a subsystem is created
or deleted, it's only updated when a listener for a
subsystem is added or removed.
So remove the nvmf_update_discovery_log() in the subsystem
create and delete paths. They just generate extra AER
completions that potentially cause the host to do unneeded
work.
Note that if a subsystem is deleted with active listeners,
the subsystem delete path will remove each of the listeners
before deleting the subsystem itself. So the discovery log
will still get updated when those listeners are removed.

When no optimal poll group exists for a qpair,
assignment for round robin happens in spdk_nvmf_tgt_new_qpair().
RDMA transport implments the logic for this assignment in
nvmf_rdma_get_optimal_poll_group().
TCP relied on the spdk_nvmf_tgt_new_qpair() instead.
This resulted in race condition when looking up and assigning
optimal poll groups - see #2113.
To remedy that, TCP now follows the same pattern as RDMA.

There is no need to sum SPDK_CEIL_DIV(length, io_unit_size) and
req->iovcnt as the later is always zero (assignment in spdk_nvmf_request_get_buffers).
Checking SPDK_CEIL_DIV(length, io_unit_size) is enough.

The specification says "host specifies an offset (i.e., LPOL and LPOU)
that is greater than the size of the log page requested, then the
controller shall abort the command with a status of Invalid Field
in Command."
Offset is used (if needed) to retrieve specific records of
Discovery Log Page, so we don't check it for Discovery Log Page.

There is a race condition between controller destruction and
subsystem state change, e.g. admin qpair may already be freed
when a namespace is added or removed. As result in function
poll_group_update_subsystem we may get heap-use-after-free error
Another problem is that some qpair's live time may exceed controller's
life time. To avoid it, start controller destruction process when the last
qpair finished the disconnect process (previously controller started
the descruction process before the last qpair starts to disconnect
and it could lead to raise conditions)

nvmf_subsystem_get_qpairs RPC handler may cause the program
could not exit normally (e.g. ctrl c). Reason is that,
spdk_get_io_channel() will be called during the getting
qpairs stream, which will add refcount value for each
existing channel. When end target, channel cannot be
destroyed since refcount be added additionally and
its value could not be subtracted to 0. As a result,
the program will hang in the process of exiting.
So here we don't need to allocate a new channel, just use
the exist one.

This commit fixes a race condition when calling free_ctrlr(),
nvmf_vfio_user_close_qpair->free_qp will set controller `ctrlr->qp[qid] = NULL`
finally, when calling free_ctrlr() we also need to check `ctrlr->qp[qid]`
is NULL or not, when there are multiple IO queues, we need a lock to protect
`ctrlr->qp[qid]`. However, the call to free_qp() in free_ctrlr() is valid
only when killing SPDK target, for all other cases, e.g: VM disconnected,
the queue pairs are already freed, so here we can process these different
cases separately, and avoid extra lock.

Ideally, SPDK should make sure no pending I/Os in this queue
pair are using the removed memory region. Currently we just
stop the submission path and leave a TODO comment here until
we have an asynchronous way to do this.
Also use the `<=` for the boundary check.

The host driver should do a wmb() before it updates the SQ tail doorbell
to ensure that any writes to the SQ are guaranteed to be visible if a
doorbell update is visible (a store-release) - and indeed, this is what
the Linux NVMe driver does.
Therefore, we require a rmb() after we read the tail doorbell in order
to synchronise properly with the host driver (we need a load-acquire),
and guarantee that the updates to the SQ are visisble to us.

When removing a listener, there's a small window when the listener is
already freed, while the controllers that were created on that listener
are still active. It happens, because the listener is removed before
disconnecting its qpairs and in turn destroying the controllers.
The ctrlr->listener pointer is now cleared when a listener is freed and
its value is checked for NULL before each use.

When a subsystem is being deleted, we disconnect all qpairs
and when the last qpair for some controller is disconnected,
we start controller desctruction process. This process requires
to send a message to subsystem's thread to remove the controller
from the list in the subsystem and after that send a message to
controller's thread to release resources.
The problem is that the subsystem also destroys all attached
controllers. This order is unpredictable and we may get
heap-use-after-free or double free.
To fix this problem we can rely on the fact that the subsystem
can only be destroyed in incative state, that means that all
qpairs linked to the subsystem are already disconnected and
all controllers are already destroyed or in the process of
destruction.
spdk_nvmf_subsystem_destroy API is now can be asyncrhonous,
it accepts a callback with cb argument.

Refine ANA state from per subsystem listener to per subsystem listener
per ANA group.
Add an array of ANA state per ANA group to subsystem listener. The array is
indexed by ANA group ID - 1.
Then in I/O paths, we get ANA state by
ctrlr->listener->ana_state[ns->anagrpid - 1].
The NVMe specification indicates the existence of NVM subsystem specific
ANA state when FFFFFFFFh is specified as NSID for the Get Features
and the Set Features commands. For these, we return the optimized state.
Update the nvmf_subsystem_get_listeners RPC to return all ANA states
of the underlying ANA groups. The nvmf_subsystem_get_listeners RPC is
not matured and not used in the test code yet. Hence compatibility is
not high priority.

This is the first patch in the patch series to control ANA states not only
as a unit of subsystem listener but also as a unit of ANA group and create
user preferred mapping between namespaces and ANA groups within a single
subsystem.
This patch adds anagrpid to both spdk_nvmf_ns and spdk_nvmf_ns_opts, and adds
ana_group array to spdk_nvmf_subsystem to count number of namespaces per ANA
group within a single subsystem. The size of the ana_group array is equal
with the size of the namespaces.
For each subsystem, allocate ana_group array regardless of the value of
ana_reporting of the subsystem.
For each namespace, at its creation, initialize anagrpid explicitly to be equal
with nsid by default and increments the corresponding entry of the ana_group
array of the subsystem regardless of teh value of the ana_reporting of thee
subsystem.
Hence the contents of the created ANA log page is not changed even if the
algorithm to crete ANA log page is changed.
Additionally this patch adds a unit test case that one ANA group
has multiple namespaces.

The map_q function is used to map Guest's physical memory address
to Host virtual address for SQ/CQ. This function can be used both
for initializing SQ/CQ and remap SQ/CQ, when used for remap SQ/CQ,
we don't need to unmap the related memory region.

Actually we should not re-enable the ADMIN queue during

we should just do the remap, but to avoid changing other

for this indirection to exist, and it would make interrupt support for the

It is better to not fail connect commands when a subsystem
is not ready. The host will not be expecting that and will
typically treat it as a catastrophic failure (i.e. it won't
retry the connect).
So instead when this situation occurs, start a poller for
the connect request. We will continue to retry processing
it until the subsystem is ready to handle it.
Fixes issue #1985.

It is possible for a controller to get added to the
subsystem before its admin_qpair has been assigned.
We need to account for that when traversing the subsystem's
ctrlr list when determining ns and ana_changes that need
to be reported for the ctrlr.
Found while doing stress testing with connects and
subsystem ns add/remove.
