We already provides the API `spdk_nvme_ctrlr_is_fabrics` to return
input controller is fabrics controller or not, but it needs a controller
data structure as the input, so here we add another API to do the same
thing and it takes the transport type as the input, with this change,
both nvme and nvmf library can use the API.
Also we should treat UINT8_MAX(255) as valid fabrics transport type.

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).

NVMe bdev module manages ANA log page itself now. So NVMe driver
should disable managing ANA log page.
Add a new option disable_read_ana_log_page to struct spdk_nvme_ctrlr_opts.
Then NVMe bdev module enables it when calling spdk_nvme_connect_async().

This fix is as same as for NVMe bdev module.
If a ANA log page has two or more ANA group descriptors, the second
or later of ANA group descriptors will not be 8-bytes aligned.
Then runtime error would occur as follows:
runtime error: member access within misaligned address 0x612000000074
for type 'const struct spdk_nvme_ana_group_descriptor', which requires
8 byte alignment
nvmf_get_ana_log_page() in lib/nvmf/ctrlr.c creates a ANA log page
data and processes 8 bytes alignment correctly because we got the
same runtime error before. However, lib/nvme had been missed at that
time.

Each time the following file
"/sys/kernel/config/nvmet/subsystems/nqn_name/namespaces/ns_id/enable"
on the target side was changed, the SPDK initiator should receive an
async event (type: SPDK_NVME_ASYNC_EVENT_TYPE_NOTICE, info:
SPDK_NVME_ASYNC_EVENT_NS_ATTR_CHANGED).
But actually not.
Since for SPDK, when target sent the non-first event, the condition
"nvmet_aen_bit_disabled(ctrl, NVME_AEN_BIT_NS_ATTR)" that prevents
target from sending event was matched.
This commit fix this issue by issuing a get_log_page cmd for each async

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().

Connect the adminq as part of controller initialization
instead of controller construction.
We never actually 'connected' the adminq for
PCIe or vfio-user transports, since its a nop.
But their connect_qpair transport ops function
is also a nop for the adminq, so it's fine to
generically connect the adminq across all transports.
Note that we cannot read registers (cc or csts)
during controller initialization now until after
the adminq has been connected since reading fabrics
registers depends on a connected adminq. This gets
special cased for now, but eventually reading
cc and csts will need to be part of the state machine
itself to make it asynchronous.

Fixes#1777.
When a qpair cannot be allocated because the transport connection fails,
the qpair was freed without unlinking it from the other structures.
This was leading to a segfault when attempting to create and free other
qpairs.
Also added a unit test to cover this case.

In some extreme use cases, an SPDK process could get
swapped out for a long period of time just after
we checked the state but before we called spdk_get_ticks().
So now we will only timeout if the timer expired before
we checked the state *and* the state did not advance.
It's possible we could just move the timeout check
to before the ctrlr->state switch, but I was
hesitant to change the flow for this case.

While I assume that the initial thought of having the
NVME_CTRLR_STATE_WAIT_FOR_* state directly after the state which it is
waiting for, was to make it clear for the reader in which order the
states will be executed.
However, it feels silly to have the same code copy pasted everywhere.
Someone who needs to add a new state will still need to edit
nvme_ctrlr_state_string() and enum nvme_ctrlr_state, which still defines
the NVME_CTRLR_STATE_WAIT_FOR_* state directly after the state which it
is waiting for.
In one way, moving the NVME_CTRLR_STATE_WAIT_FOR_* states to the end of
nvme_ctrlr_process_init(), when reading nvme_ctrlr_process_init(), it is
actually easier to see the ordering of the states which actually do
something of significance.

This patch is the first of the patch series to make spdk_nvme_detach()
asynchronous.
We have lengthy shutdown notification, i.e., we have to wait a long time
until shutdown processing is completed, in some SSDs. If the running system
has many such SSDs, we see large intolerable delay.
SPDK provides a controller option, no_shn_notification as a workaround.
We can use the workaround if the use case of the detach is to switch to
the next application without system reboot. However, we cannot use the
workaround if we want to do system reboot after detach.
To mitigate such lengthy shutdown notification, we need to parallelize
detachment among SSDs.
Hence the patch series will introduce an asynchronous detach API and
will use the API to parallelize detachment.
This patch adds the following changes.
Introduce a context structure and separate nvme_ctrlr_shutdown()
itno nvme_ctrlr_shutdown_async() and nvme_ctrlr_shutdown_poll_async()
using the context structure.
Name the context structure as nvme_ctrlr_detach_ctx because it will be
used only in internal APIs. The upcoming public APIs will support
multiple detachment and will have the contest structure named as
spdk_nvme_detach_ctx.
Use TSC instead of counter because polling interval will be controlled
by the caller.
Use the convenient macro, SPDK_CEIL_DIV(), to round off the time
value in milliseconds.

Since namespace types were introduced in NVMe, the CC.CSS register
has a new value (SPDK_NVME_CC_CSS_IOCS) which indicates that all
supported command sets should be selected/enabled. This possibly
includes command sets other than NVM and ADMIN only.
Therefore, if a SPDK application wants enable all the command sets
that the controller supports, it has to explicitly set
opts->command_set to SPDK_NVME_CC_CSS_IOCS.
To avoid possibly a lot of SPDK applications having to set this
parameter, check if the user requested a command set explicitly,
if not, make SPDK automatically use the most reasonable default,
based on the supported bits set by the controller.
The most common case is that you want to enable (all) the command
sets that the controller supports.
A user will still be able to restrict the controller to only use
the NVM command set (or ADMIN only), by setting opts->command_set
to a specific value.
Since the current default command set value specified by
spdk_nvme_ctrlr_get_default_ctrlr_opts() is SPDK_NVME_CC_CSS_NVM,
which is defined as 0, we cannot know if the user specified a
command set explicitly or not.
To solve this, change the default command set value specified by
spdk_nvme_ctrlr_get_default_ctrlr_opts() to CHAR_BIT (0x8), which
is larger than the largest value that can be set in CS.CSS (which
is only 3 bits wide, thus 0x7).

The new NVME_CTRLR_STATE_IDENTIFY_NS_IOCS_SPECIFIC state is added
after the NVME_CTRLR_STATE_IDENTIFY_ID_DESCS state. This is because
we need to have fetched the identifiers in the desc list in order
to know which command set a namespace belongs to.
A slightly nicer design might have been to refactor the NVMe state
machine to first fetch the id desc list, then the identify namespace

However, since this would have required a lot of changes, it didn't
