This patch introduces asynchronous versions of the ctrlr_(get|set)_reg
functions. Not all transports need to define them - for those that it
doesn't make sense (e.g. PCIe), the transport layer will call the
synchronous API and queue the callback to be executed during the next
process_completions call.

This new API signals that the ctrlr will soon be
reset. This allows the transport to skip unnecessary
steps in following calls to the driver prior to the
reset - for example, skipping PCIe DELETE_SQ/CQ
commands when freeing an IO qpair.
Note that if we are deleting a qpair after
prepare_for_reset was called, and the qpair is
still waiting for a CREATE_IO_CQ or CREATE_IO_SQ,
we cannot poll for those commands to complete,
but we also cannot free the qpair immediately.
So set a flag for this case to defer the
destruction until the outstanding CREATE_IO_CQ or
CREATE_IO_SQ callback is invoked (typically as an
aborted command when the reset happens).

The pcie layer can't always detect bad addresses
in the request at submission time - for example,
the transport may not have any trackers available
and the request gets queued at the generic
nvme level.
So this means that we might detect vtophys failures
during submission time, or in a process_completions
context - the latter happening when we complete
one request which triggers submitting a new request.
Currently if the vtophys failure happens during
submission context, we return -EFAULT to the
caller *and* call the completion callback. Nowhere
else in the driver do we do both - the intention
has always been that you get one or the other.
So make all of this consistent by tagging the
tracker and the qpair with a flag if we hit a vtophys
error in the submission path. Return 0 to the caller,
who will then later get a completion callback for the
bad request when the qpair is next processed for
completions.
I considered a separate TAILQ to hold these 'bad'
trackers, but that would have required duplicating
quite a bit of the tracker completion code for this
one case. The flag on the pqpair is already in the
hot cacheline, so it's cheap to check it. We will
only interate the outstanding_tr list when that flag
is set, so this should have zero impact to performance.
Fixes issue #2085.

We map the SPDK_NVME_TRANSPORT_* values directly to
the NVMe-oF trtype values. Since PCIe isn't
Fabrics, we choose 256 which is outside of the
8-bit trtype range of values.
So we can just check if trtype >= 256 to determine
if the trid is for fabrics or not. This is
preferable to checking PCIE || VFIOUSER in case
additional non-fabrics transport types are added
in the future.
I considered taking a trid as the parameter instead,
but went this route since it is consistent with
the existing spdk_nvme_ctrlr_is_discovery().

A very heinous error case is when a delete_io_sq or
delete_io_cq command fails when freeing a PCIe IO
qpair. In that case we return an error to the caller,
and the resources are not freed.
Instead of trying to 'fix' this error case, let's
just tell the user that if freeing an IO qpair fails,
the user should reset the controller and try again.
Resetting the controller will do one of two things:
1) The subsequent create_cq/create_sq will succeed,
at which point, trying to delete again should work
fine. (If it doesn't, it indicates some kind of
horrendous SSD.)
2) The subsequent create_cq/create_sq will fail,
at which point the entire ctrlr would fail and
need to be detached. This could result in some
leaked memory, but seems unavoidable.

spdk_nvme_ctrlr_cmd_get_log_page_ext()), avoid creating a third one for
now, since nvme_ctrlr_get_zns_cmd_and_effects_log() itself can leverage
one of the existing public functions.

Make enum spdk_nvme_ctrlr_flags more readable.
Other enums in spdk, e.g. enum accel_capability,
and enum NVME_RDMA_COMPLETION_FLAGS, already define
the enum values using bit shifts.
Do the same for enum spdk_nvme_ctrlr_flags.
No functional change intended.

It is possible that a single probe_ctx could be used
to probe multiple newly attached nvme controllers. If
one of those controllers is removed during this process,
the rest of the controllers do not get probed and can
even get stuck in a zombie state.
It is better to just continue with probing the rest of
the controllers.
Fixes issue #1611.

Add two new public APIs, spdk_nvme_detach_async() and
spdk_nvme_detach_poll_async() to detach multiple controllers in parallel
as a simple manner to users.
Hold the target controller to nvme_ctrlr_detach_ctx because users
will free any object which held it after returning spdk_nvme_detach_async().
spdk_nvme_detach_ctx holds all nvme_ctrlr_detach_ctx in a sequence
by linked list.
spdk_nvme_detach_ctx has a boolean variable polling_started to prevent
the user from calling spdk_nvme_detach_async() while
spdk_nvme_detach_poll_async() is called repeatedly.

Move ZNS specific functions to their own header file:
include/spdk/nvme_zns.h.
This is similar to how it's done for e.g. NVMe-oF with
include/spdk/nvmf.h.
This avoids cluttering the nvme.h header with ZNS specific functions.
A SPDK program that wants to use the spdk_nvme_zns_* functions will
need to include include/spdk/nvme_zns.h, however, this is similar
to how e.g. spdk_nvmf namespaced functions work.
This change is safe to do now, since there is no SPDK release with
ZNS so far.

In cases where the SPDK nvme driver is being used as a validation/test
vehicle, users may need to allocate a currently unused qid that can be
used for creating queues using the raw interfaces. One example would be
testing N:1 SQ:CQ mappings which are supported by PCIe controllers but
not through the standard SPDK nvme driver APIs.
These new functions fulfill this purpose, and ensure that the allocated
qid will not be used by the SPDK driver for any future queues allocated
through the spdk_nvme_ctrlr_alloc_io_qpair API.
