The API spdk_nvme_ctrlr_free_io_qpair() returns immediately if the
passed qpair is NULL, but calling spdk_nvme_ctrlr_free_io_qpair()
with NULL should be avoided.
This patch cleans up the code to ensure that nvme_ch->qpair is NULL if
disconnected and spdk_nvme_ctrlr_free_io_qpair() is called only if
nvme_ch->qpair is not NULL.
Then add a test scenario that two reset requests were submitted
simultaneously and the first reset request failed and then the second
reset request also failed. This verifies the refactoring done in the
next patch.

Add support for zoned namespaces in the bdev/nvme module.
Query the namespace type, and if a zoned namespace is found, set the
bdev struct members needed by the bdev_zone.h APIs.
Note that while vbdev_zone_block and bdev_ocssd have zone locks,
bdev/nvme does not need any kind of zone lock, because NVMe ZNS
supports append natively.
The whole point of the zone append command is that you don't need any
locks, even when having multiple writers, since the drive will return
back the Assigned LBA where the blocks were actually written.
If a SPDK application will utilize writes instead of zone appends,
the SPDK application itself will need a per zone lock in order to
make sure that there is only one outstanding write.
Adding zone locks in bdev/nvme would reduce the performance of zone
appends, for no reason at all.

The recent refactoring removed the destruct poller and change the

sending message.
But differentiating callback function is difficult if we reset multiple
ctrlrs.
If nvme_bdev_ctrlr->destruct is set, any new reset cannot start. So we can
use an new variable and always execute the callback function.
Add an new variable pending_destruct to struct nvme_bdev_ctrlr, and set
pending_destruct if ctrlr->ref is zero and ctrlr->destruct is true, and
then start destruct ctrlr if ctrlr->destruct_after_reset is set after
clearing pending resets.

In nvme_bdev_ctrlr_create, calloc will be called with a zero size
allocation request if the number of namespaces is zero. The behaviour
is implementation defined if the size of the space requested is zero -
calloc will either return a pointer that mustn't be dereferenced, or
NULL. If NULL is returned, the nvme_bdev_ctrlr_create will fail.
Only call calloc if there are a non-zero number of namespaces.
Otherwise, leave the namespaces pointer with a NULL value. All
references to namespaces[] are either known to be safe, or occur
in the context of looping through the namespaces which will be
skipped if the count is zero. The exception to this is in
vbdev_opal_create, where an assert has been added to match
equivalent code in bdev_ocssd_create_bdev.
Tested by running unit tests on a system that returns a null pointer
for a zero size allocation.

It has been confirmed that there is no affected use case in
the SPDK community when we remove the range parameter from
the bdev_ocssd_create RPC.
Hence, remove the range parameter from the bdev_ocssd_create RPC,
remove range parameter from bdev_ocssd_create_bdev(), remove range
info from ocssd_bdev_config_json(), and then update unit tests
accordingly.

To allow SO_MINOR updates on LTS for the whole year it is supported,
the major version for all components needs to be increased.
This is to prevent scenario where two versions exists with matching
versions, but conflicting ABI.
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 quarterly 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 21.04
release.
This patch:
- increases SO_VER by 1 for all components
- resets SO_MINOR to 0 for all components
- removes suppressions for ABI tests

When we do detect new devices, we would like to get them
attached as quickly as possible. Controller initialization
requires a non-trivial number of admin commands, and when
using async probe, it means that after we have detected
a new device, it will take many iterations of calling
spdk_nvme_probe_poll_async() before the controller is
fully attached.
So when we are actively probing a probe_ctx, create
a new poller that is solely responsible for probing
that context at a much higher frequency.

bdev_nvme_submit_request() calls bdev_nvme_get_buf_cb() directly
when the buffer is already allocated. This is for performance improvement
but will be helpful for the upcoming multipath feature to retry
read I/O submission because buffer should be allocated only once.
By reading the code a little more critically, bdev_nvme_submit_request()
can call bdev_nvme_readv() directly in this case, and do in this patch.

nvme_bdev_ctrlr pointer is already cached to nvme_io_channel.
Hence let's remove it from the helper functions, bdev_nvme_create_qpair()
and bdev_nvme_destroy_qpair().
The following minor fixes are done together in this patch.
Fix the error paths of bdev_nvme_create_qpair() because
bdev_nvme_destroy_qpair() cannot be used as is in this case.
When calling bdev_ocssd_destroy_io_channel(), check if nvme_ch->ocssd_ch
is not NULL instead of spdk_nvme_ctrlr_is_ocssd_supported().
Cache nvme_bdev_ctrlr to nvme_io_channel just before calling

When a device is removed, we should use the remove_cb
that was specified when the device was originally probed
and attached, if one was set.
Also add a new spdk_nvme_ctrlr_set_remove_cb API. This
can be used for cases where a different remove_ctx is
desired than was specified for the probe call. This
also enables setting a remove_cb when using connect APIs
which do not have a way currently to provide a remove_cb.
This also requires fixing the bdev nvme module, which
was depending on the previously errant behavior.

This is very clean because spdk_bdev_io is processed by the generic bdev

This patch is the first of the series and add ocssd_bdev parameter
