efcae1bdee accel: method for getting accel memory domain
This will allow drivers to check if a task is using buffers from accel
domain.  This is just a helper, since the same can be achieved by
calling `spdk_memory_domain_get_first("SPDK_ACCEL_DMA_DEVICE")`, but
there's only a single accel domain and it is a bit special, so it makes
sense to have a dedicated helper function for getting it.

b2454dfbcc accel: introduce platform drivers
The goal of a platform driver is to execute chained accel operations in
the most efficient way possible.  A driver is aware of the hardware
available on a platform and can execute several operations as a single
one.  For instance, if we want to do DMA and then encrypt the data, the
driver can do both at the same time, if the hardware is capable of doing
that.

Platform drivers aren't required to support all operations.  If a given
operation cannot be executed, the driver should notify accel to continue
processing a sequence, via spdk_accel_sequence_continue(), and that
operation will processed by a module assigned to its opcode.

It is required however, that all platform drivers support memory
domains, including the "virtual" accel domain.  A method for allocating
those buffers will be added in the following patches.

This patch only adds methods to register and select platorm drivers, but
doesn't change the way a sequnce is executed (i.e. it doesn't use the
driver to execute it).

b12419a231 tcp: don't abort requests waiting for R2T ACK
It is possible for requests waiting for R2T ACK to receive H2C PDU
before receiving the ACK.  Therefore, the following sequence:

1. Host sends a write request to the target.
2. Target sends R2T PDU to the host and sets request's state to
   AWAITING_R2T_ACK.
3. Host sends H2C PDU to the target, but it doesn't reach the target
   yet.
3. Host sends an abort command to abort that request.  Request's state
   is changed to READY_TO_COMPLETE.
4. Target receives the H2C PDU, sees that request's state is
   READY_TO_COMPLETE, which is unexpected, and terminates the
   connection.

will cause the target to terminate the connection, which is obviously
incorrect.

So, to avoid that, we can treat AWAITING_R2T_ACK state in the same way
as TRANSFERRING_HOST_TO_CONTROLLER and register a poller waiting for the
state to be changed.

Fixes #2789.

a7eb6187e5 bdev: implement claims v2
This implements the v2 claims API. Compared to the original v1 claims,
v2 claims:

- Support read-write-once, read-write-many, and read-only-many claims.
- Are claimed with spdk_bdev_module_claim_desc().
- Are associated with a bdev descriptor that is passed to
  spdk_bdev_module_claim_bdev_desc().
- Are released upon close of the bdev descriptor used to obain the
  claim.
- Cannot be taken when a descriptor other than the one passed to
  spdk_bdev_module_claim_bdev_desc() has write access.

Later commits in this series are needed to fully integrate them with the
bdev subsystem.

6dc9dbe5ca env_dpdk: don't call remove_rte_dev from secondary proc
During secondary process shutdown, when nvme device
would get detached, it would trigger env_dpdk to
send rte_eal_hotplug_remove event for the corresponding
BDF.  But this isn't valid from a secondary process -
we can only attach/detach from the primary process.

Usually this would just result in a bunch of annoying
print messages as the secondary and primary process
sent rte messages between each other.  But occasionally
one of the response messages from the primary process
could arrive just as the secondary process was going
through rte_eal_cleanup.  The message would get
kicked to the DPDK intr thread, we would do bus_cleanup
which frees all of the PCI state, and then the message
would execute on the intr thread causing seg faults,
use-after-free or some other violation.

It's possible some kind of cleanup should be
implemented in DPDK, but for now, let's just not
induce incorrect behavior from SPDK, and don't send
the hotplug_remove messages from a secondary
process.

Fixes issue #2651.

cf64422ad7 bdev: call unregister callback on correct thread
We should always called the unregister callback on
the same thread that spdk_bdev_unregister() was
originally called.  So save the thread pointer and
use an spdk_thread_send_msg() to make sure it gets

finishes.

Also add unit test that reproduces the original
issue.

bbd3d96b85 nvme_rdma: Ignore response if its QP was already destroyed
This is a workaround but is necessary to fix the github issue #2874.
Due to some unknown reason, in nightly test with Intel e810 NICs
when a qpair is created with synchronous mode and connection errors
are detected, the qpair is destroyed even if requests for the qpair are
still inflight. Then, nvme_rdma_process_recv_completion() causes NULL
pointer acccess. To fix this NULL pointer access, change
nvme_rdma_process_recv_completion() to return immediately if rsp->rqpair
is NULL. Add a TODO comment to find a root cause and really fix the
issue.

One of the fixes for the issue #2874.
