This domain is meant to represent data being transformed by accel
engine. Users will be able to allocate buffers from that memory domain
and use them when appending operations to an accel sequence.
Since these buffers are only meant to be used as placeholders for actual
buffers, none of the push/pull/translate callbacks are implemented. To
access the data after it was transformed by accel, users should make
sure that the final command's destination buffer isn't allocated from
accel memory domain.

Operation sequence should always be treated as a whole, meaning that
users cannot rely on the contents of any intermediate buffers and should
only care about the buffer that's the destination of the whole
operation. This allows us to remove some of those copy operations by
changing source / destination buffer of a preceding / following
operation.
If a sequence is using buffers from non-local memory domain, users can
append a copy operation to a sequence to specify a local destination
buffer. If the module executing the operations is aware of memory
domains, this can avoid doing an extra spdk_memory_domain_pull_data().

This patch introduces the concept of chaining multiple accel operations
and executing them all at once in a single step. This means that it
will be possible to schedule accel operations at different layers of the
stack (e.g. copy in NVMe-oF transport, crypto in bdev_crypto), but
execute them all in a single place. Thanks to this, we can take
advantage of hardware accelerators that supports executing multiple
operations as a single operation (e.g. copy + crypto).
This operation group is called spdk_accel_sequence and operations can be
appended to that object via one of the spdk_accel_append_* functions.
New operations are always added at the end of a sequence. Users can
specify a callback to be notified when a particular operation in a
sequence is completed, but they don't receive the status of whether it
was successful or not. This is by design, as they shouldn't care about
the status of an individual operation and should rely on other means to
receive the status of the whole sequence. It's also important to note
that any intermediate steps within a sequence may not produce observable
results. For instance, appending a copy from A to B and then a copy
from B to C, it's indeterminate whether A's data will be in B after a
sequence is executed. It is only guaranteed that A's data will be in C.
A sequence can also be reversed using spdk_accel_sequence_reverse(),
meaning that the first operation becomes last and vice versa. It's
especially useful in read paths, as it makes it possible to build the
sequence during submission, then, once the data is read from storage,
reverse the sequence and execute it.
Finally, there are two ways to terminate a sequence: aborting or
executing. It can be aborted via spdk_accel_sequence_abort() which will
execute individual operations' callbacks and free any allocated
resources. To execute it, one must use spdk_accel_sequence_finish().
For now, each operation is executed one by one and is submitted to the
appropriate accel module. Executing multiple operations as a single one
will be added in the future.
Also, currently, only fill and copy operations can be appended to a
sequence. Support for more operations will be added in subsequent
patches.

We currently use a hack AllowDuplicatedIsid with the
iSCSI target to allow running multiple Calsoft tests
in parallel, since each Calsoft test always uses the

But this causes some tests to intermittently fail,
likely due to changed behavior with many sessions
sharing the same InitiatorName. The problem is
very difficult to reproduce, and made worse since
the Calsoft tests themselves are binary only.
So instead split the tests into two sets - one set
contains nopin-related tests which each take longer
to run due to various interval expirations needed for
the test. There are just a few of these tests, and
do not appear to ever cause an intermittent failure,
so we run these in parallel. The rest are all run
serially and run rather quickly.

The idea behind "iobuf" is to have a single place for allocating data
buffers across different libraries. That way, each library won't need
to allocate its own mempools, therefore decreasing the memory footprint
of the whole application.
There are two reasons for putting these kind of functions in the thread
library. Firstly, the code is pretty small, so it doesn't make sense to
create a new library. Secondly, it relies on the IO channel abstraction,
so users will need to pull in the thread library anyway.
It's very much inspired by the way bdev layer handles data buffers (much
of the code was directly copied over). There are two global mempools,
one for small and one for large buffers, and per-thread queues that hold
requests waiting for a buffer. The main difference is that we also need
to track which module requested a buffer in order to allow users to
iterate over its pending requests.
The usage is fairly simple:
```
/* Embed spdk_iobuf_channel into an existing IO channel */
struct foo_channel {
...
struct spdk_iobuf_channel iobuf;
};
/* Embed spdk_iobuf_entry into objects that will request buffers */
struct foo_object {
...
struct spdk_iobuf_entry entry;
};
/* Register the module as iobuf user */
spdk_iobuf_register_module("foo");
/* Initialize iobuf channel in foo_channel's create cb */
spdk_iobuf_channel_init(&foo_channel->iobuf, "foo", 0, 0);
/* Finally, request a buffer... */
buf = spdk_iobuf_get(&foo_channel->iobuf, length,
&foo_objet.entry, buf_get_cb);
...
/* ...and release it */
spdk_iobuf_put(&foo_channel->iobuf, buf, length);
```

This check was put in place as a workaround for some specific kernel
builds which were mainly shipped under centos8. Since we already
dropped centos8 in the CI and replaced it with rocky8 (where kernel
is actually stable) there's no value in maintaining that anymore.

There may be some timing issue where attempt to rebind the ctrl from
vfio_pci driver back to nvme, right after issuing the
bdev_nvme_detach_controller() call, fails as the vfio_pci might have
not fully released the device yet.
To mitigate, simply kill the application (as it's not needed anymore
at at point) before starting the kernel_target test - this should give
enough time for the device to be properly released.
As a precaution, make setup.sh to retry the probe attempt in case it
fails.

Using new_id attribute is global in scope, meaning that depending
on the kernel's setup seen prior running setup.sh, single write
to it may re-bind ALL matching devices. This doesn't play well
with our PCI_{ALLOWED,BLOCKED} options as they can't be enforced
in such a case. Consider the following example:
> modprobe -r nvme # all nvme ctrls are detached from the kernel
> echo 0xdead 0xbeef >/sys/bus/pci/drivers/uio_pci_generic/new_id
# setup.sh-wise
> modprobe -r nvme
> PCI_BLOCKED=some:dead:beef.bdf setup.sh
# PCI_BLOCKED device still ends up bound to userspace driver.
After this single write, ALL matching devices will end up bound to
uio_pci_generic. To avoid this, we should override preferred driver
on per-bdf basis.

This is in prep for adding a new compressDev accel_fw
module that will contain all of the DPDK compressDev specifics
on it, the vbdev will make calls to the accel_fw instead.
As the accel_fw has SW based compression, we want the configure
option to apply to building the vbdev module but not the accel_sw
software implementation or the upcoming compressdev module.
Renamed to "compress" as reduce is a term specific to the vbdev
implementation of the compression to be provided by the accel_fw
and thus the same reason why we leave the test flag called REDUCE
because it's controlling tests for the reduce library as well as
the vbdev module that is using reduce. The flag does not apply
to the SW implementation of compression.
This does not affect upcoming accel_fw compressdev module, that
will have its own configure option.

When SRQ is supported, recv objects will be allocated by poll group
and qpair will associated and use them. In this case, we do not want
qpair to allocate and free recv objects. When connection is established,
it will be decided if SRQ is used or not. Hence, defer recv objects
allocation until connection is established.
Send objects are not affected directly by SRQ, but
nvme_rdma_register_reqs() no longer does any registration and deferring
send objects allocation makes the code more consistent. Hence, defer
send objects allocation until connection is established too.
Even after this patch, we rely on nvme_rdma_ctrlr_delete_io_qpair()
to free resources completely.
