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.

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.

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.

We could not restore the setting of ana_reporting because it was not
included in the JSON config dump.
Add the parameter ana_reporting into JSON config dump by adding and
using a new helper function nvmf_subsystem_get_ana_reporting().
Besides, previously the JSON RPC nvmf_subsystem_get_listeners had
ana_state regardless of the value of ana_reporting. We make it
conditional in this patch. The JSON RPC nvmf_subsystem_get_listeners
had not been used in the test code in the repository. Hence this
change will be acceptable.

Similar with Create IO SQ command, we should also defer the completion
of Delete IO CQ command until the IO QP is disconnected finally. However,
since the NVMf library will disconnect/free the queue pair finally, we
can't use the queue pair data structure to save the context, so define
a delete_cq context for Delete IO CQ command.

The NVMf library doesn't process Create IO SQ command, so for
this command we will use a fabric connection command instead,
however, the fabric connect command is called asynchronously,
so we need to defer the completion for Create IO SQ command after
fabric connect command is completed.
Fix issue #2043.

The VM may already delete all queue pairs and just leave the
socket when killing VM, so we can check number of connected
queue pairs here, if no connected queue pairs, free the
controller immediately.
It's an optimization so that we don't need to loop all
queue pairs below.

"A host may replace its reservation key without regard to its registration
status or current reservation key value by setting the Ignore Existing Key

So for this case we treat it as a new registrant, also add UT to cover

Since we are using NVMf fabric library to emulate a PCIe based SSD via
vfio-user target, so there maybe some commands that are related with
PCIe SSD only, such as set/get features with interrupt coalescing
and Interrupt Mask Set/Interrupt Mask Clear registers. Even the
NVMf library doesn't support that, it is not a fatal error to Host
NVMe driver, so here we use the info log instead of error log for
this case so that to avoid noise logs.
Fix#2036.

The NVMf library will not implement interrupt coalescing and ignore them, but we can
report this via get_features.
Some OS may check the result from get_features so that it will not send set_features
for interrupt coalescing.

Users may switch kernel NVMe driver to SPDK NVMe driver
in the VM, without this fix, we will got "AERL exceeded"
response very frequently, because the AERs submitted by
previous driver will never be aborted in runtime.

When users remove kernel NVMe driver in the VM, after 120 seconds,
SPDK NVMf target will disconnect ADMIN queue pair due to association
timer timeout, and for vfio-user transport, the ADMIN queue pair
connection is associated with the socket connection, so when probing
the NVMe controller again, because there is no active ADMIN connection
for fabric register R/W commands, it will cause segment fault.
Here we set the association timeout value to 0 for vfio-user transport,
so that the ADMIN connection will not be disconnected when shutdown the
controller, the ADMIN queue pair will be disconnected when the socket
connection breaks.
