If a lot of qpairs are connected all at once, the
RDMA optimal_poll_group logic does not work correctly,
because it only accounts for qpairs that received
their CONNECT capsule. Now that we have a counter
for a poll group's unassociated qpairs, use that value
to supplement the current io qpair count.
We can just assume for now that all of these unassociated
qpairs are io qpairs. That won't always be true, but
for purposes of picking the optimal poll group it is
sufficient.
Note that for RDMA, we could increment the counters
based on the RDMA qpair ID in the private data in the
rdmacm connect, but to keep the code simpler and common
across all transports, we defer the accounting until
after receiving the CONNECT command, so that it is
the same for all transports.
Fixes issue #2800.

We make decisions on how to pick a poll group for a new
qpair by looking at each poll group's current_io_qpairs
count. But this count isn't always accurate since it
doesn't get updated until after the CONNECT has
been received.
This means that if we accept a bunch of connections
all at once, they may all get assigned the same poll
group, because the target poll groups counter doesn't
get immediately incremented.
So add a new counter, current_unassociated_qpairs,
to account for these qpairs. We protect this counter
with a lock, since the accept thread will increment
the counter, and the poll group thread will
decrement it when the qpair receives the CONNECT
allowing us to associated with a subsystem/controller..
If the qpair gets destroyed before the CONNECT is
received, we can use the qpair->connect_received
flag to decrement current_unassociated_qpairs.

Currently we use qpair->ctrlr at qpair destroy
time to decide if we need to decrement the
qpair's poll group's qpair count. But this is
not correct - these counters get incremented
when the CONNECT is received, but qpair->ctrlr
doesn't get set until later.
So add a new connect_received bool to the spdk_nvmf_qpair.
Use this instead to determine when we should decrement
the poll group qpair counters.

Note, that command support in the controller is initialized once on
controller create. If another namespace which doesn't support copy
command is added to the subsystem later, it will not be reflected in
the controller data structure and will not be communicated to the

To support SQs allocated to a poll group other than the controller's
main poll group, we need to make sure to poll those SQs when we wake up
and handle the controller interrupt. As they will be running in a
separate SPDK thread, we will arrange for all poll groups to wake up
when we receive an interrupt corresponding to a vfio-user message
arriving.
This can mean needless wakeups: we don't (yet) have a mechanism to only
wake up the poll groups that correspond to a particular SQ write.
Additionally, as we don't have any notion of a poll group per
controller, this ends up polling all SQs in the entire poll group, not
just the ones corresponding to the controller we were handling.
As this has potential performance issues in many cases, it defaults to
disabled.

The word engine was both used (interchangeably with module) to refer to
the things that plug into the framework and to the framework itself.
This patch eliminates all use of the word engine that meant the
framework. It leaves uses of the word that meant "module".

If initiator and target run on the same application, and initiator
uses SRQ, target may get async events for initiator, e.g.,
IBV_EVENT_QP_LAST_WQE_REACHED unexpectedly.
The reason is initiator and target may use the same device
simultaneously and only target polls async events.
Target sets attr.qp_context to rqpair when creating QP, but initiator
sets attr.qp_context to NULL when creating QP.
Hence one simple fix is to ignore async events whose qp_context is
NULL.

Multiprocess is only supported by a few libraries (e.g. NVMe driver).
Other libraries that don't support it will often fail on mempool
initialization when running as a secondary process, as the mempools are
already created by the primary process. But the error messages are
vague and don't indicate why this happened. So, this patch adds a check
to see if a mempool exists after spdk_mempool_create() fails and prints
an error message informing users that multiprocess is unsupported.

Fixes #issue 2636.
The existing allocation method (nvmf_rdma_get_optimal_poll_group())
is traversal and unperceived link disconnection. A more fair method
considering the number of real-time connections to allocate a poll
group is implemented.
