It is now possible to append an operation calculating crc32c to an accel
sequence. A crc32c operation needs special care when it's part of a
sequence, because it doesn't have a destination buffer. It means that
we can remove copy operations following crc32c only when it's possible
to change the dst buffer of the operation preceding crc32c.

It is quite common for a user to use the exact same iovec (in memory) to
describe buffers for two different operations. If that iovec was
describing accel buffer, accel would modify it replacing it with an
actual buffer. This is broken if that iovec was used by some other task
in a sequence, as accel wouldn't be aware that it has been changed too.
To address this, accel will use a new iovec from the aux_iovs array. It
means that accel buffers always *must* be passed using a single iovec.
Theoretically, users could chunk that buffer into several iovecs, but
spdk_accel_get_buf() always returns a single buffer, so, in practice,
this should never happen, and therefore is unsupported.

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

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).

This is to prevent scenario where two versions exists with matching

Ex. Next SPDK release adds an API call increasing the minor version,
then LTS needs just a subset of those additions.
Increasing major so version after LTS, allows the future releases
to update versions as needed. Yet allowing LTS to increase minor
version separately.
Disabled test for increasing SO version without ABI change, as
that is goal of this patch. This check shall be removed with SPDK 23.05

Looks like this was left over from prior LTS, to avoid that
make sure it is only skipped when running against v23.01.x as latest

- increases SO_VER by 1 for all components
- resets SO_MINOR to 0 for all components
- removes suppressions for ABI tests

If a task has buffers in a remote memory domains, we'll now allocate a
buffer from local memory and replace the original buffer with it. This
is the first step in supporting buffers in remote memory domains. To
fully support it, we'll also need to pull/push the data before/after
executing a task.

All operations are using iovecs to describe their buffers and only
encrypt/decrypt additionally used nbytes to store the total size of a
src buffer. We don't really need this value in the generic accel code,
so we can let modules calculate it, if necessary. That way, we won't
waste cycles calculating it if a module doesn't use it and it makes the
code a bit easier, as we won't have to deal with the fact that nbytes is
only valid for certain operations.

Also, since this was the last operation using dst and nbytes, these
fields were removed from spdk_accel_task.
