This will allow drivers to check if a task is using buffers from accel

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

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).

Accel modules can now implement the get_memory_domains() callback to
indicate the types of memory domains they support. If unimplemented, a
module is assumed not to support memory domains and accel will take care
of pulling/pushing data to local buffers prior to passing a task to be
executed by a module.
For now, similarly to the bdev layer, we only check if a module supports
memory domains, but we don't verify the types of the domains. That
could be easily added in the future, if necessary.

This patch is first in the series of patches aimed to make all accel
operations describe their buffers with iovecs. The intention is to make
it easier to handle tasks in a generic way.
It doesn't mean that we change the API - all function signatures are
preserved. If a function doesn't use iovecs, we use the aux_iovs array.
However, this does mean that each accel module that provides support for
a given operation will need to be adjusted to use iovecs.
Additionally, update the unit test checking copy elision to verify the
buffers of the copy operation that is left.

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.

It'll make it possible to change some of the impl_opts options on a
per-socket basis, as well as make it easier to use fields common to all
implementations in the generic layer.

This patch defines a new function, spdk_sock_readv_async(), which allows
the user to send a readv request and receive a callback once the
supplied buffer is filled with data from the socket. It works simiarly
to asynchronous writes, but there can only be a single outstanding read
request at a time.
For now, the interface isn't implemented and any calls will return
-ENOTSUP. Subsequent patches will add support for it in the uring
module and as well as emulation in the posix module.

The bdev_lvol_grow_lvstore will grow the lvstore size if the undering
bdev size is increased. It invokes spdk_bs_grow internally. The
spdk_bs_grow will extend the used_clusters bitmap. If there is no
enough space resereved for the used_clusters bitmap, the api will
fail. The reserved space was calculated according to the num_md_pages
at blobstore creating time.

In SPDK, declarations have the return type on the same line. Definitions
have the return type on a separate line. Astyle has an option for
enforcing this. Unfortunately, it seems to have two bugs:
1) It doesn't work correctly at all on C++ files.
2) It often fails on functions that return enums, or long type names
Deal with 1) by adjusting the check_format.sh script to only tell astyle
to fix return type line breaks for C files and not C++. Deal with 2) by
adding a few typedefs to work around the problem.

Many open source projects have moved to using SPDX identifiers
to specify license information, reducing the amount of
boilerplate code in every source file. This patch replaces
the bulk of SPDK .c, .cpp and Makefiles with the BSD-3-Clause
identifier.
Almost all of these files share the exact same license text,
and this patch only modifies the files that contain the
most common license text. There can be slight variations
because the third clause contains company names - most say
"Intel Corporation", but there are instances for Nvidia,
Samsung, Eideticom and even "the copyright holder".
Used a bash script to automate replacement of the license text
with SPDX identifier which is checked into scripts/spdx.sh.

Not all PDUs that have can have data can also have padding - e.g.
C2HTermReq has data, but cannot have padding and the PDO field should be
reserved. Therefore, for these PDUs the data starts exactly at the end
of the header (and its digest, if present) and we shouldn't be using PDO
to calculate its offset.
This fixes handling for the C2HTermReq PDUs, as it used to be broken and
usually (if target set PDO=0) resulted in an overflow when calculating
psh_len.
