When doing live migration we need to restore the AER commands
in the destination VM, so here to provide an API to save
these CIDs and the transport layer can save the value.
After migration in destination VM, we should allocate
new AER requests based on CIDs in vfio-user.

This reverts commit eb09178a59.
Reason for revert:
This caused a degradation for adminq.
For adminq, ctrlr_delete_io_qpair() is not called until ctrlr is destructed.
So necessary delete operations are not done for adminq.
Reverting the patch is practical for now.

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)

This patch is first in series that reworks vhost library
with two goals in mind:
1) Refactor vhost and vhost-blk to no longer depend on rte_vhost.
All references to that API will be moved to rte_vhost_user.c.
2) Add a transport abstraction for virtio-blk devices.
vhost-blk will now be able to expose virtio-blk using multiple
implementations of the interface.
First one will be vhost_user that depends on DPDK rte_vhost library.

From SAM-4, section 5.13 (Sense Data);
“When a command terminates with a CHECK CONDITION status, sense data shall be returned
in the same I_T_L_Q nexus transaction (see 3.1.50) as the CHECK CONDITION status. After
the sense data is returned, it shall be cleared except when it is associated with a unit
attention condition and the UA_INTLCK_CTRL field in the Control mode page (see SPC-4)
contains 10b or 11b.”
SPDK does not set UA_INTLCK_CTRL to 10b or 11b, so we set the unit attention condition
immediately against a single IO or Admin IO after reporting it via a CHECK CONDITION.
Once the failed IO received at iSCSI initiator side, it will be retried. In the case of
resize operation, if there is no IO from iSCSI initiator side, the unit attention
condition will be delayed to report until the first IO is received at the iSCSI target
side.
Meanwhile, we clear the resizing (newly added) flag on our SCSI LUN structure after
first time we report the resize unit attention condition.
The kernel initiator won’t actually resize the corresponding block device automatically.
It will report a uevent, and then you can set up udev rules to trigger a rescan. SPDK
iSCSI initiator will automatically report the LUN size change.

We will assign each SQ with different poll group in round
robin way by default, this may cause race condition to
post completions to one CQ in different threads, so here
we will assign the SQs which share one CQ into same poll
group.
Also enable multiple cores NVMe compliance tests so that
to cover shared IO CQ case.

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.

libvfio-user will call quiesce callback when there are
memory region add/remove and device state change requests
from client, and in the quiesce callback, we will pause
the subsystem so that it's safe to do everything after
it, then after quiesce callback, we will resume the
subsystem. The quiesce callback is also used in
live migration, each device state change will quiesce
the device first.

Users may remove the listener while VM is connected, the endpoint is
associated with Unix Domain socket file, we should destroy the endpoint,
however, the controller maybe still active for now, because nvmf
library will help us to disconnect all queue pairs in asynchronous
way. Here we use the same way as the NVMf library to destroy the
controller when there is no connected queue pairs.
Fix#2246.
