4216f7fff5 nvmf/vfio-user: fix shared CQ usage case
Multiple IO Submission Queue can share one Completion Queue, and
we use field 'cqid' to save it in Submission Queue, so when posting
completion response, we need to get the Submission Queue's CQID first,
then post the completion queue based on CQID.

Also rename vfio-user internal variables with 'vu_' prefix in this
function.

1d4a88104d vfio-user: correct return code for library context poller
Currently, the poller that calls vfu_run_ctx() always returns SPDK_POLLER_BUSY.
Update libvfio-user and adjust the API usage so that it can accurately
report SPDK_POLLER_IDLE when needed.

Additionally, renaming the poller to better reflect its meaning: it's not just
for mmio handlers, but libvfio-user handling in general.

814cd25882 nvmf: optimize log level for unsupported feature IDs and invalid property offset
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.

695425c776 nvme: move spdk_nvme_map_cmd to nvmf/vfio-user
Nvmf/vfio-user uses this API to map NVMe command sent from
VM from Guest Physical Address to Host Virtual Address, so
now we moved this API from the nvme library to nvmf/vfio-user
as an internal API.

UT code will be added back in coming patch.

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.

ac3a42b15c nvmf: retry connect commands internally when subsys not ready
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.

b503ef4fa0 nvmf: Fix heap-use-after-free when poll_group_remove() is called after ctrlr is freed
When a qpair is destroyed and the qpair is the last,
_nvmf_ctrlr_free_from_qpair() (in lib/nvmf/nvmf.c) sends two messages,
one is for _nvmf_ctrlr_destruct() and another is for
_nvmf_transport_qpair_fini().

We do not know which of two completes earlier.

_nvmf_ctrlr_destruct() frees the qpair->ctrlr in the end.
On the other hand, _nvmf_ctrlr_free_from_qpair() calls
spdk_nvmf_poll_group_remove() in the end, and spdk_nvmf_poll_group_remove()
accesses the qpair->ctrlr to free queued requests to the qpair.

Before one recent change, spdk_nvmf_poll_group_remove() had been called
before _nvmf_ctrlr_free_from_qpair() was called.

Hence extrace the operation to free queued requests from
spdk_nvmf_poll_group_remove() and inline it into _nvmf_qpair_destroy().

Fixes one showstopper error to investigate the issue reported in #1819.

164bfddf24 nvmf: don't set aerl=0 for non-discovery controllers
Commit b7cc4dd added support multiple AERs, but didn't
remove the code that hardcodes aerl=0 for non-discovery
controllers.  So even though the target now supports
multiple AERs, we never indicate that for non-discovery
controllers.

The spec also recommends that implementations support
a minimum of 4 AERs - so the current behavior is not
recommended.

It seems that at least on Windows (when testing with
vfio-user transport) we see the limit get exceeded
which results in ERRLOGs.  Let's keep the ERRLOG there
for now, assuming that once we report we support 4
AERs that Windows won't try to send more than that.

Fixes issue #2000.
