some systems (especially virtual machines) don't have an IOMMU capable

When we use async writev (e.g., lib io_uring), we find that
the callback of writev is executed after recving the new
data from the initiator, and this is possible.
For example, if the NVMe-oF TCP target receives the ic_req from the
initiator, and sendout the ic_resp, the state of tqpair will change from
invalid to running until the callback is executed. And the data of ic_resp
is already sent to the initiator, and we receive the new command later. However,
we may still not get the call back function executed
(i.e, spdk_nvmf_tcp_send_icresp_complete). And it is possible
for using lib io_uring, I faced this issue when using lib uring.

then the subsystem will allow dynamic listen address binding. For such
subsystems,
* When a FC port comes online, FC transport will add port's address
to subsystem's listen list.
* When a FC port goes offline, FC transport will remove port's address
from subsystem's listen list.
If subsystem definition has 1 or more valid "Listen" directives then FC ports
coming online or going offline will not affect subsystem's listen address
whitelist.

Added new public header for zoned bdev. Zoned bdev is an
extension of the bdev interface. Generic concept comes
from ATA/SCSI and is also being worked as an NVMe TP.
Zoned device logical blocks space is divided into fixed-sized
zones. Each zone is described by its start logical block address
and capacity. Writes to a single zone need to be sequential.
After zone is fully written it need to be reset to write to it
again. Such writing schema could be very beneficial in terms of
write amplification factor for NAND based devices.
SPDK Flash Translation Layer library will be consuming this
interface in the future.
Extending SPDK bdev interface will allow to use existing bdev
infrastructure for this new type of devices.
Zoned device have several properties defined in spdk_bdev
structure:
- zone_size: default size of each zone
- max_open_zone: maximum number of open zones
- optimal_open_zones: optimal number of open zones to get
best performance on writes
Single zone properties are defined in spdk_bdev_zone_info
structure:
- start_lba: first logical block of z zone
- write_pointer: logical block address in the zone at
which next write shall occur.
- capacity: maximum number of logical blocks that may
be written in the zone when zone is empty.
- state: zone state
Several zone states are defined: Empty, Open, Full, Closed,
Read Only and Offline.
To change zone state zone actions are defined: Close, Finish,
Open and Reset.

spdk_pci_device_claim() could create a file on the
filesystem that couldn't be deleted programatically.
It could only be overwritten - e.g. by another spdk
instance - but this didn't really work if that
another instance had less privileges and hence no
access to the previous file.
This is exactly the case we're seeing on our CI when
running SPDK as non-root. In general it's a good idea
not to leave any leftover files, so now we'll delete
the pci claim file when the spdk process exits.
spdk_pci_device_claim() used to return a file descriptor
that could be simply closed to "un-claim" the device.
It'll now return only a return code. The fd will be
stored inside spdk_pci_device and will be closed either
when user calls the newly introduced spdk_pci_device_unclaim(),
or when the device is detached.
We'll still need to clean up those files somewhere in
our test scripts (probably ./setup.sh cleanup) to
clean up after crashed processes or so - but we don't
necessarily want to run such scripts inside the autotest
whenever a non-root spdk is about to be started.

spdk_nvme_detach() will do the normal shutdown notification for
most cases, and it will take some time e.g. 2 seconds to finish
the process for PCIe based controllers. If users' environment
has several drives, each drive will call spdk_nvme_detach() one
by one, and the shutdown process may take very long time.
Since users know exactly what they would like to do for the next
step, so here we provide an option to users, users can enable it
to skip the shutdown notification process so that they can have
very quick shutdown process, and when starting next time, the
controller can be enabled again.

DPDK defines the minimum alignment as "suitable for any
kind of variable (in the same manner as malloc())", but
internally the alignment is always rounded up to the
cache line size, even if the requested alignment is 0.
We would like to start relying on this behavior in FTL,
where lba maps are allocated using DMA-able memory and
are constantly looked up or modified by different threads.
By having the lba maps unaligned, we risk having those
threads pollute each other's cache lines.
Rather than enforcing this memory alignment in FTL, we
do it in spdk_*malloc directly. In general it makes
sense to have DMA-able memory always cache-line-size
aligned for the same reason as above.

- Create four split vbdevs on the NVMe bdev.
- Add the split vbdevs to a NVMe-oF target.
- Application is aware of block address space of the split vbdevs.
- Application submits read/write I/O to the NVMe-oF target.
Case 1:
- Configure NVMe-oF target to DIF pass-through.
Case 2:
- Configure NVMe-oF target to DIF insert/strip
For the case 1,
- Application inserts DIF for write I/O and verifies DIF for read I/O.
- The split vbdevs remaps reference tags of DIF both for read and write
I/O because application expects reference tags are based on the
block address space of split vbdevs.
- The NVMe bdev processs read/write I/Os without remapping reference tags
because reference tags are already based on the block address space
of the NVMe bdev.
For the case 2,
- NVMe-oF target inserts DIF for write I/O, and verifies and strips
DIF or read I/O.
- The split vbdevs remaps reference tags of DIF both for read and write
I/O because NVMe-oF target expects reference tags are based on the
block address space of split vbdevs.
- The NVMe bdev processs read/write I/Os without remapping reference tags
because reference tags are already based on the block address space
of the NVMe bdev.
This patch adds two APIs, spdk_dif_ctx_set_remapped_init_ref_tag
and spdk_dif_remap_ref_tag to satisfy the use case.
UT code is added together in this patch.

When DIF is inserted or stripped, nvme_tcp_pdu_set_data_buf must
shift the range of the buffer from LBA based to extended LBA based

temporary iovec array to leave a space of metadata for each block then.
This patch do the following:
- Add a pointer to the current DIF context to struct nvme_tcp_pdu.
This pointer is set when DIF is inserted or stripped to the current
NVMf request.
- When the pointer to the current DIF context in the PDU is set, get
the extended LBA based offset and length by calling
spdk_dif_get_range_with_md() and use them in nvme_tcp_pdu_set_data_buf().
- Original data length is set in the PDU and original data offset is
set in the current DIF context in nvme_tcp_pdu_set_data_buf().
- Add UT code.

NVMe/TCP target had assumed the size of each iovec was io_unit_size.
Using nvme_tcp_pdu_set_data_buf() instead removes the assumption
and supports any alignment transparently.
Hence this patch moves nvme_tcp_pdu_set_data_buf() to
include/spdk_internal/nvme_tcp.h and replaces the current code to use it.
Besides, this patch simplifies spdk_nvmf_tcp_calc_c2h_data_pdu_num()
because sum of iov_len of iovecs is equal to the variable length now.
We cannot separate code movement (lib/nvme/nvme_tcp.c to include/
spdk_internal/nvme_tcp.h) and code replacement (lib/nvmf/tcp.c)
because moved functions are static and compiler give warning if
they are not referenced in lib/nvmf/tcp.c.
The next patch will add UT code.

For NVMe/TCP target, data segments which correspond to H2C or C2H PDU
will have any alignment. spdk_dif_set_md_interleave_iovs() have allowed
reading data to have any alignment but had required data segment to
be a multiple of block size.
In other words, spdk_dif_set_md_interleave_iovs() had required that both
ctx->data_offset and (data_offset + data_len) must be a multiple of the
data block size.
This patch refines the algorithm to remove the latter requirement.
The update implies that spdk_dif_set_md_interleave_iovs support any
data buffer whose size is less than a single data block.
The update doesn't change parameters of spdk_dif_set_md_interleave_iovs
and existing UT should be passed.
This patch adds additional UT code to test these updates.
