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 the port of the vbdev compress logic into the accel
framework. It includes just one enhancement, to only fill each
mbuf in either src or dst array with max "window size" param to
avoid QAT errors. Note that DPDK ISAL PMD was not ported as we
have native ISAL compression in accel now.
Note: ISAL w/DPDK is still built w/this patch, that can't be
removed until the vbdev module moves to accel fw as it still
depends on DPDK ISAL PMD.
Follow-on patches will include addition C API for PMD selection,
this patch just gets equivalent functionality going. Upcoming
patches will also convert the vbdev compress module to use the
accel framework instead of talking directly to compressdev.
More patches will also address comments on vbdev common code
that addressed here would make the review challenging.
This patch also fixes a bug in the ported code that needs to
be fixed here to pass CI. Capability discovery was incorrect
causing all devices to appear to not support chained mbufs,
with the mbuf splitting code this is important to get right.

Error counters for NVMe error was added in the generic bdev layer but
we want to know more detailed information for some use cases.
Add NVMe error counters per type and per code as module specific
statistics.
For status codes, the first idea was to have different named member
for each status code value. However, it was bad and too hard to test,
review, and maintain.
Instead, we have just two dimensional uint32_t arrays, and increment
one of these uint32_t values based on the status code type and status
code. Then, when dump the JSON, we use spdk_nvme_cpl_get_status_string()
and spdk_nvme_cpl_get_status_type_string().
This idea has one potential downside. This idea consumes 4 (types) *
256 (codes) * 4 (counter) = 4KB per NVMe bdev. We can make this smarter
if memory allocation is a problem. Hence we add an option
nvme_error_stat to enable this feature only if the user requests.
Additionally, the string returned by spdk_nvme_cpl_get_status_string()
or spdk_nvme_cpl_get_status_type_string() has uppercases, spaces, and
hyphens. These should not be included in JSON strings. Hence, convert
these via spdk_strcpy_replace().

completions, thus xnvme_queue_poke() returns immmediatly, the user can
then call xnvme_queue_poke() as frequently as desired. This requires
xNVMe v0.5.0. Earlier versions will ignore 'opts.poll_io' for 'libaio'.
For 'io_uring', xNVMe is instructed via 'opts.poll_io' to enable
IORING_SETUP_IOPOLL.
For 'io_uring_cmd', xNVMe is instructued via 'opts.poll_sq' to enable
IORING_SETUP_SQPOLL, this sets up a kernel-side thread reaping
completions from user-space on the ring. Note that 'io_uring_cmd'
requires liburing >= 2.2.
This commit enables the above by default. The above can be disabled by
setting 'conserve_cpu' to true on the bdev-setup.

This is only relevant when rpc.py is running in server mode. Recent
changes in argparse under python3.11 force it to raise the
ArgumentError exception whenever subparser of the same name is being
added.
With that in mind, avoid extra call to spdk_rpc_plugin_initialize()
by keeping track of all plugins that were already successfully
initialized.

This gives us a place to initialize iobuf pools, specify subsystem
dependencies, and execute RPCs to configure the sizes of the pools.
We allow users to configure the size of the pools either through the
options in spdk_bdev_opts or through the new RPC, iobuf_set_options.
The second option has higher priority, so it will override the options
set by the bdev layer.

Both max and min should be reset periodically. We can use the queue
depth sampling poller to reset these but the queue depth sampling poller
is optional. We extend the bdev_reset_iostat RPC to support mode to
reset all or only max/min fields.

Add a helper function bdev_reset_device_stat() to reset I/O statistics.
This funciton is used for the bdev_reset_iostat RPC.
We do not have any plan to use bdev_reset_device_stat() outside
lib/bdev. Hence, we do not add this as a public API.
Then, add a new RPC bdev_reset_iostat to reset I/O statistics of a
single bdev or all bdevs.
Resetting I/O statistics affects all consumers. Add a note to CHANGELOG
and doc/jsonrpc.md.
