This patch adds an API spdk_scsi_bdev_get_dif_ctx().
spdk_scsi_bdev_get_dif_ctx() decodes opcode in CDB, and if opcode
is read or write block commands, it gets LBA and use the lower
32bits of LBA as Reference Tag. It gets DIF information from
specified bdev next. Then it sets all to DIF context and return.
spdk_scsi_bdev_get_dif_ctx() is exported to iSCSI through
spdk_scsi_lun_get_dif_ctx().

When the specified buffer size to spdk_bdev_io_get_buf() is greater
than the permitted maximum, spdk_bdev_io_get_buf() asserts simply and
doesn't call the specified callback function.
SPDK SCSI library doesn't allocate read buffer and specifies
expected read buffer size, and expects that it is allocated by
spdk_bdev_io_get_buf().
Bdev perf tool also doesn't allocate read buffer and specifies
expected read buffer size, and expects that it is allocated by
spdk_bdev_io_get_buf().
When we support DIF insert and strip in iSCSI target, the read
buffer size iSCSI initiator requests and the read buffer size iSCSI target
requests will become different.
Even after that, iSCSI initiator and iSCSI target will negotiate correctly
not to cause buffer overflow in spdk_bdev_io_get_buf(), but if iSCSI
initiator ignores the result of negotiation, iSCSI initiator can request
read buffer size larger than the permitted maximum, and can cause
failure in iSCSI target. This is very flagile and should be avoided.
This patch do the following
- Add the completion status of spdk_bdev_io_get_buf() to
spdk_bdev_io_get_buf_cb(),
- spdk_bdev_io_get_buf() calls spdk_bdev_io_get_buf_cb() by setting
success to false, and return.
- spdk_bdev_io_get_buf_cb() in each bdev module calls assert if success
is false.
Subsequent patches will process the case that success is false
in spdk_bdev_io_get_buf_cb().

Allow user to add seed value for guard compuation to DIF context.
This will avoid the guard being zero in case of all zero data.
NVMe controller doesn't support seed value for guard computation
explicitly, and hence if we want to use such a seed value in
NVMe controller, we have to format metadata more than 8 byte,
and add seed value into the reserved metadata field.
But some popular iSCSI/FC HBAs and SAS controllers have supported
seed value for guard computation, and so supporting seed value
in the SPDK DIF library is very helpful for some use cases.
Hence this patch makes the DIF library possible to specify seed
value for those use cases.

to generate functions like spdk_bdev_module_register_187().
Typically, this is not a problem as these functions are not called directly
rather, they are only used as constructor functions to load the bdevs during
system startup.
There are languages however, (e.g rust) that require these functions to be
referenced explicitly to prevent them from being removed during the linking phase.
In order to reference them, having the names predictable (and potentially
changed per commit) makes things easier.

This patch is for DIF check types.
Add enum spdk_dif_check_type to DIF library.
Add a field dif_check_flags to struct spdk_bdev and add
spdk_bdev_is_dif_check_enabled to bdev APIs.
Added enum is intended to improve usability. If no enum, the
caller will have to get raw data of flags and mask each bit.

This patch is for DIF settings.
Add fields dif_type and dif_is_head_of_md to struct spdk_bdev and
add APIs spdk_bdev_get_dif_type and spdk_bdev_is_dif_head_of_md to
bdev APIs.
The fields dif_type and dif_is_head_of_md are added to the JSON
information dump.

Next patch will introduce enum spdk_dif_check_type for user to
know easily if checking DIF field is enabled or not.
This patch renames bitmask macros from SPDK_DIF_*_CHECK to
SPDK_DIF_FLAGS_*_CHECK to avoid mis-interpretation .
Using FLAGS was derived from SPDK_NVME_IO_FLAGS_PRCHK_* in
include/spdk/nvme_spec.h.

To support DIF, bdev will need to expose the following information:
- Metadata format
- Block size
- Metadata size
- Metadata setting (interleave or separate)
- DIF settings
- DIF type 1, 2, or 3
- DIF location
- DIF check types
- Guard check
- Reference tag check
- Application tag check
This patch is for the metadata format. Subsequent patches will do for the DIF
setting and DIF check types.
Add fields, md_len and md_interleave, to struct spdk_bdev and add APIs,
spdk_bdev_get_md_size and spdk_bdev_is_md_interleaved, to bdev APIs.
The fields, md_len and md_interleave, are added to the bdev JSON infomation dump.
DIF will be used only in the NVMe bdev module and the upcoming virtual
DIF bdev module first. But additional required storage by md_len and md_interleave
will be very small and they are simple. Hence add them to struct spdk_bdev simply.

Removed their various usages inside the core vhost code
together with the external events themselves. External
events were completely replaced by spdk_vhost_lock()
and spdk_vhost_dev_find().

Vhost external events no longer do any asynchronous
calls, they only lock the vhost mutex and directly
call the provided function. The mutex encapsulation
isn't worth the additional complexity of splitting
each vdev-handling code into multiple functions, so
we expose low-level APIs that should eventually
replace external events entirely.
Instead of:
```
static int do_something_cb(struct spdk_vhost_dev *vdev, void *arg)
{
struct my_data *ctx = arg;
/* access the vdev and ctx */
free(ctx);
}
struct my_data *ctx = calloc(...);
rc = spdk_vhost_call_external_event("my_vdev", do_something_cb, ctx);
if (rc != 0) { /* err handling */ }
```
We can now do just:
```
spdk_vhost_lock();
vdev = spdk_vhost_dev_find("my_vdev");
if (vdev == NULL) { /* err handling */ }
/* access the vdev any context data */
spdk_vhost_unlock();
```
