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.

Moved this to the SW module (part of the accel engine) so the
caller doesn't have to worry about. Allowed for a few simplifcations
in the tool as well.
Also, instead of using send_msg to call the completion we add it to
a list in the sw module that a new poller uses to perform the
completions as this is more efficient the sending a message to the

The new design:
* Supports a generic batching capability in the accel_fw layer
that keeps track of hw accelerated vs sw commands based on
the capabilities of the engine and processes sw commands in the
generic layer while sending a list of commands (not a batch)
to the engines for processing.
* Batch completions are managed via the generic layer, when using
the accel_fw the engines only process commands. With DSA however,
if a list of commands is sent down it will use the DSA public
API to create and send batches but will rely on the generic layer
to complete the batch task itself. When using DSA directly, batching
works as usual (DSA handles batch completion).
* The engine function tables were greatly simplified by replacing
all of the individual entries (copy, fill, crc32c, etc) with one
`submit_tasks` function that is used to both send lists of tasks
for batches or just one task for single shot API.
* Internally batching is now used to re-submit tasks that were queued
for flow control reasons.

The one large global mempool was a waste of memory for apps that
don't use the accel framework as its always allocated a pool sized
to handle a heavy load with multiple threads.
Instead move to a per channel list of just 1024 tasks greatly
decreasing the memory footprint but still able to scale as more
threads are added.
Also renamed all accel_req to acccel_taak and simply task to
accel_task as this was being touched anyways and not consistent.

Added to the framework as well as all 3 engines. Needed by apps
in the event that they have to fail following the creation of a
batch, allows them to tell the framework to forget about the batch
as they have no intent to send it.

This was sort of a clunky interface requiring a couple of inline
functions in every app that wants to use the accel_fw moving
forward. By having the accel_fw public API accept a callback arg
instead of an accel_task combined with adding a pool of accel_tasks
in the accel_fw engine we can eliminate this.
After changing the parm to a cb_arg, changes were made to all accel_fw
interfaces to put cb_fn and cb_arg as the last parms in public and
private function calls.
Related bdev_malloc changes need to be in this patch in order to pass CI.

When an engine has not filled out an entry point for an accel_fw
function, call the sw implmentation that's built into the accel_fw
transparently.
Also update the accel_perf app to no longer block attempts to use
capabilities not reported as supported by the selected engine but
instead to print an informational message.
The exception is batch related commands as their implementation
is specific to the engine.

This patch only includes the basic framework for batching and the
ability to batch one type of command, copy. Follow-on patches will
add the ability to batch other commands and include an example of
how to do so via the accel perf tool. SW engine support for batching
will also come in a future patch. Documentation will also be coming.
Batching allows the application to submit a list of independent
descriptors to DSA with one single "batch" descriptor. This is beneficial
when the application is in a position to have several operations ready
at once; batching saves the overhead of submitting each one separately.
The way batching works in SPDK is as follows:
1) The app gets a handle to a new batch with spdk_accel_batch_create()
2) The app uses that handle to prepare a command to be included in the
batch. For copy the command is spdk_accel_batch_prep_copy(). The
app many continue to prep commands for the batch up to the max via
calling spdk_accel_batch_get_max()
3) The app then submits the batch with spdk_accel_batch_submit()
4) The callback provided for each command in the batch will be called as
they complete, the callback provided to the batch submit itself will be
called then the entire batch is done.
