This patch removes references to deprecated PMEM from accel library.
The code that was executed when ACCEL_FLAG_PERSISTENT flag is set,
is no longer needed and is removed.
_sw_accel_copy() function is removed and replaced with memcpy(), as
after PMEM removal its functionality is the same as memcpy().
_sw_accel_dualcast() is no longer needed, replaced with direct calls
to memcpy()
Removed 'flags' parameter - it is no longer needed
accel_ut.c: removed references to PMDK
deprecation.md updated
ACCEL_FLAG_PERSISTENT flag will be removed in next patch.

If a driver is registered and selected, it'll now be used to execute
sequences of accel operations. The driver has priority over accel
modules, so the modules will only be used to execute operations that the
driver cannot perform.
Once driver completes a task (or a number of tasks), it notifies accel
using standard spdk_accel_task_complete(). To let accel continue
processing a sequence, driver can call spdk_accel_sequence_continue().
This can be done when the driver executes all tasks (1), an error occurs
(2), or the driver doesn't know how to execute a given opcode (3). In
case of (3), that operation will be executed using appropriate accel
module and, while the rest of the sequence will be sent back to the
driver.

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.

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".

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.

We enable multiple engines by:
* getting rid of the globals that point to the one available HW
and one available SW engine
* adding a submit_tasks() entry point for the SW engine so that
it is treated like any other engine allowing us to just call
submit_tasks() to the assigned engine for the opcode instead of
checking what is supported
* changing the definition of engine capabilities from
"HW accelerated" to simply "supported"
* during init, use a global (g_engines_opc) that contains engines
and is indexed by opcode so we know what the best engine is for each
op code
* future patches will add RPC's to override engine priorities or
specifically assign an opcode(s) to an engine.

In support of upcoming patches and to greatly simplify things,
the capabilites enum which held bit positions for each opcode
has been removed. Only the opcodes enum remains and thus only
opcodes are used throughout. For the capabiltiies bitmap a helper
function is added to convert from opcode to bit position. Right
now it is used in the IO path but in upcoming patches that goes away
and the conversion is only done at init time.

Fill is sent in as a uint8, we need to populate the full uint64

how idxd was doing it, instead of adding the same code to ioat just
move it up a layer.
