90c56d965d lib/accel: Two crc32c APIs are added to provide the chained crc32 operation support
This patch provides two new accelerated crc32c function interface.
And the next patch will be used to add the real support of chained crc32c feature.

17bb748a60 accel: Move non-engine specific batch to the accel_fw layer
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.

8d059e7a18 accel: add API to cancel a batch sequence
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.

fc250841ca idxd: add batch capability to accel framework and IDXD back-end
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.

d5b059dedc accel: add new API to discover an engine's capabilities
This patch also implements the new API for the 3 existing engines.
There was also some minor clean in one file, moving a function to
eliminate multiple forward declarations (there would have been
another one with this new API).

The next patch will use this API in the accel perf tool.
