The controller concept in NVMf is like a session, for any
new connection in nvmf_vfio_user_accept() with the endpoint,
we treat it as a new controller, we don't need the `ready`
field in controller to indicate the connection state, we
need the connection state in endpoint, so here just use
endpoint->ctrlr point to indicate the socket connection
is valid or not.

Currently we allocate buffers perf each SGL descriptor.
That can lead to a problem when we use NVME bdev with
PRP controller and length of the 1st SGL descriptor is
not multiple of block size, i.e. the initiator may send
PRP1 (which is SGL[0]) which end address is page aligned
while start address is not aligned. This is allowed by
the spec. But when we read such a data to a local buffer,
start of the buffer is page aligned when its end is not.
That violates PRP requirements and we can't handle such
request. However if we use contig buffer to write both
PRP1 and PRP2 (SGL[0] and SGL[1]) then we won't meet
this problem.
Some existing unit tests were updated, 1 new was added.

2) use __SPDK_BDEV_MODULE_ONLY #define
The latter allows nvmf to just get the spdk_bdev_module
definitions and APIs that it needs for claiming bdevs
for purposes of avoiding the same namespace used in
different subsystems.
This also ensures that future changes to structures
like spdk_bdev and spdk_bdev_io will not cause
lib/nvmf so version changes.
Note: we include bdev_module.h explicitly in the
nvmf/subsystem unit tests now, before including

knowing the internal structure of spdk_bdev.

The QEMU may only use one page for a memory region, we are sure
these memory regions will not be used as NVMe data buffers.
Previously libvfio-user will help us to round up these memory

nvmf_poll_group_remove_subsystem_msg() disconnects all
qpairs associated with controllers in the specified
subsystem. If it finds any controllers that need to
be disconnected, it sends a message to the running
thread to execute the same function again later.
But when it runs again later, the qpair may no longer
be in the poll group, but there could still be
outstanding messages being sent between threads. For
example, _nvmf_qpair_destroy() needs to send a message
to the ctrlr->thread to clear the qpair mask bit.
All of this could result in the nvmf target starting
to destroy poll groups prematurely. Destroy poll
groups results in the nvmf spdk_threads exiting. If
there are still messages being processed from
the STOP_SUBSYSTEMS target state, we can get
use-after-free errors since processing of those
messages could access freed memory associated with
the exited thread.

Max data tranfer size is defined in NVMe-oF spec as 2^(mdts cmd field) * 4KB.
Mdts cmd field is calculated as spdk_u32log2(transport->opts.max_io_size / 4096),
so max_io_size < 8KB results in mdts=0, which means no size limit (according to spec).
User can set max_io_size = 0 explicitly to allow no size limit.

When we iterate qpairs that belong to a subsystem

some qpair can be disconnected on transport level,
e.g. the initiator may receive a disconnect for
the first qpair and disconnect others. That may lead
to a dead loop when we call spdk_nvmf_qpair_disconnect
with a callback, the callback is called immediatelly
and tries to disconnect the qpair again.
To solve this problem, move part of nvmf_poll_group_remove_subsystem
function to another function nvmf_poll_group_remove_subsystem_msg
which disconnects all qpair at once without any callback
and calls itself via thread_send_msg untill all qpairs are
disconnected.

SPDK block devices can only be resized up when

pausing the subsystem is enough.
Also modify the ns_hotplug_test to do null bdev

The current implementation treats HPDA/CPDA as the absolute offset
to the beginning of the PDU where the payload data starts. This is
incorrect. The HPDA/CPDA actually specify where the payload data
should start such that the starting location is a multiple of HPDA
(for C2H PDU) or CPDA (for H2C PDU or CapsuleCmd PDU).
The other issue fixed is that the current implementation calculates
padding only when header digest is enabled. This is also incorrect.

Aspects of bit fields are 'implementation defined'. On some platforms
alignment will occur if two adjacent fields are of different types. This
occurs in spdk_nvme_feat_async_event_configutation after the crit_warn
member which is effectively an int8_t, followed by an int16_t. There
isn't a generic way of changing the compiler's behaviour, so the best
options are:
- Change crit_warn to a uint32_t bit field and copy the value to/from
a spdk_nvme_critical_warning_state variable to use it. This requires
changes to code using the field.
- Adjust the structure definition to use smaller types to avoid the
problem. This preserves existing semantics, but the field order will
need to be reviewed if big-endian support is ever added (other places
in nvme_spec.h will need similar attention). A second reserved field
is required.
Use smaller types which seems the most straightforward option. Adjust
the use of the spdk_nvme_feat_async_event_configuration reserved fields
in lib/nvmf/ctrlr.c.
The new structure is binary compatible and the fields behave in the same
way, with the exception of an additional reserved field, so updating
CHANGELOG.md probably isn't necessary.

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 quarterly releases
to update versions as needed. Yet allowing LTS to increase minor

To estimate the number of bytes that can be written

This patch has dependency on libvfio-user library, users can start NVMe identify/perf
examples.
Usage:
1. Start nvmf_target.
2. Use RPC to create a subsystem with namespace bdev.

Currently, file /var/run/muser/domain/muser0/8/ctrlr is the socket file which is used
to transfer socket messages between target and client.

This reverts commit 0bcaf050d7.
Reason: After this patch, the last nvme command cannot be executed

(1) The qpair is in waiting for available req state.
(2) There is no incoming data again (i.e.. no read in event).

This reverts commit 9ef1496ba5.
Reason for revert: The public API spdk_nvmf_qpair_get_listen_trid() was
overlooked when this patch is created. Then the code to use the trid was
replaced by spdk_nvmf_qpair_get_listen_trid(). To avoid someone from using
the trid in future, revert this patch. struct spdk_nvmf_qpair is defined]
in the public header file, nvmf_transport.h but it is mainly for pluggable
custom transport.
Any custom transport will not use the trid, and so even if we remove it,
we will have no issue.

Delete connection code is scattered all over the place for
different scenarios. For FC-NVME2, we also need to have
ability to delete single connection at runtime. Cleanup delete
connection code and have a signle nvmf_fc_del_connection api that
can be used in all scenarios.

1) Create fc_req pool per fc connection based on SQ size. This gives more flexibity.
2) Remove create_max_aq_conns_test as it is not longer valid. We dont have any limit
on number of AQ connections based on the HW RQ size.

nvmf_subsystem_state_change() protects against going
starting the pause/change/resume chain again if we
haven't completed the previous chain. But add
some asserts to make sure the cb_fn and cb_args
never get set twice. This also requires setting
them back to NULL after they've been used.

iWARP doesn't support this ibv async event.
Probably some clean up of SRQ needs to be done, e.g.
post dummy drain WR to SRQ and wait for its completion
when qpair is being destroyed.
