Unit tests for spdk_strtol/spdk_strtoll use hard coded strings for
arithmetic constants (LONG_MIN/MAX etc). These are only valid
on platforms where both long and long long are 64-bit values.
Replace the hardcoded values with strings generated from limits.h.
The tests use values that are outside of the MIN/MAX range, which
cannot be represented as int64_t. These are calculated in two parts
to avoid overflow and recombined as a string.
Verified using the unit tests on two different architectures and with
test code to check that the generated string is the same as the
hardcoded value on x86 Linux. Used a small test program to calculate
+/-30 around each limit value to check carry handling and boundary
conditions.

When using stacked virtual bdev (e.g. split virtual bdev), block
address space will be remapped during I/O processing and so reference
tag will have to be remapped accordingly.
The use case is explained in detail as follows:
- Format a single NVMe SSD with DIF enabled.
- Create a NVMe bdev on the NVMe SSD with DIF enabled.
- 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.

Data offset are intended to correspond to DATAO in NVMe/TCP and
Buffer Offset in iSCSI.
Previously for iSCSI, buffer offset had been merged to start block
address, but passing buffer offset separately from start block address
clarifies the logic more.
On the other hand, for NVMe/TCP, passing DATAO separately from start
block address will be critically important because DATAO will bave any
alignment and will be necessary to use for not only reference tag
but also guard computation.
This patch adds data_offset to struct spdk_dif_ctx and adds it to the
parameters of spdk_dif_ctx_init(). ref_tag_offset is also added to struct
spdk_dif_ctx and it is computed by dividing data_offset by data_block_size
and is used to compute reference tag.
The next patch will use this change when getting DIF context in SCSI.

Currently iSCSI target have used a single contiguous data buffer
both for read and write I/O. Hence spdk_dif_set_md_interleave_iovs
accepts a single contiguous data buffer and its size as arguments.
On the other hand, NVMe-TCP target recently has changed to use
SGL data buffer instead.
DIF strip and insert will be supported in NVMe-TCP target next,
and updating spdk_dif_set_md_interleave_iovs to accept SGL data
buffer will be helpful.
This patch changes the interface of spdk_dif_set_md_interleave_iovs,
but allows only a single iovec. The next patch will allow multiple
iovecs.

Subsequent patches will share the struct among iteration and

_dif_sgl. The name sgl has been already adopted widely in SPDK.

This patch adds an API spdk_dif_set_md_interleave_iovs().
This function is used to leave a space for metadata for each block
when the network socket reads data, or to make the network socket
ignore a space for metadata for each block when the network socket
writes data. This function removes the necessity of data copy in
the SPDK application during DIF insertion and strip.

Previously, test data buffer was filled by one value, 0xAB, but
this may not be enough to detect future potential issues.
ut_data_pattern_verify() already did per-byte check, but size of
test data buffer is small and completion time of tests is not long.
So, even if we change ut_data_pattern_generate() to set per-byte
data instead of memset(), extra overhead of test completion time
will be negligible.

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.

Error check of strtol is left to users of it. But some use cases
of strtol in SPDK do not have enough error check yet.
For example, strtol returns 0 if there were no digits at all.
It should be avoided for each use case to add enough error checking
for strtol.
Hence spdk_strtol and spdk_strtoll do additional error checking
according to the description of manual of strtol.
Besides, there is no use case of negative number now, and to keep
simplicity, spdk_trtol and spdk_strtoll allows only strings that
is positive number or zero.
As a result of this policy, callers of them only have to check if
the return value is not negative.
Subsequent patches will replace atoi to spdk_strtol because atoi
does not have error check.
