6716729c9c dif: Create iovec array so that a space for metadata is left for each block
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.

2fefd9f53c ut/dif: Fill test data buffer by cyclic values to find potential issues
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.

8696cd4288 dif: Add seed value for guard to avoid 0 in case of all zero data.
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.

b78e763c1a string: spdk_strtol to delegate additional error checking
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.

3f836b036f dif: Fix opposite definition of DIF location parameter from SPDK NVMe API
SPDK NVMe driver and NVMe CLI define the parameter about DIF location as
follows:

If set to 1 and DIF is enabled, then DIF is transferred as the first 8
bytes of metadata. If set to 0 and DIF is enabled, then DIF is transferred
as the last 8 bytes of metadata. Defaults to 0.

This patch fixes the apparent inconsistency.

These APIs follow realloc about buffer management, i.e., the original
buffer is left untouched if they fail.

Besides, the original buffer is NULL, they are equivalent to
sprintf_alloc() and vsprintf_alloc(), respectively.

7c56c393ba bit_array: return UINT32_MAX if no cleared bits found
spdk_bit_array_find_first_set() returns UINT32_MAX if no
set bits are found.  But spdk_bit_array_find_first_clear()
would return the size of the bit array instead in this case.
(Note: the comments say size of the bit array + 1 which was
incorrect)

So this patch makes spdk_bit_array_find_first_clear()
consistent with spdk_bit_array_find_first_set() and returns
UINT32_MAX if no cleared bit is found.

spdk_io_device_register() doesn't have a return value, but we can at
least catch trivial mistakes like neglecting to pass a valid io_device
or create/delete callback in debug builds.

One invalid unit test case that passed NULL for all parameters is
removed, since there's no way to make that work without adding a return
value instead of asserts.

601bcbcf66 util: extend cpumask to hold more than 64 cpus
Fixes github issue #218.

This patch introduces spdk_cpuset object to store and manipulate
the set of individual CPUs. The main objective of this object is
to replace cpumask declared as uint64_t and extend the limitation
of supported CPUs (lcores) above 64 CPUs.

spdk_cpuset is always allocated dynamically and accessed by opaque
pointer, what makes it easier to extend in the future without
breaking API/ABI.

This patch also extends parsing function allowing to set cpumask
using a list of cpus e.g. "[0-4,10,12]" sets mask of 0,1,2,3,4,10,12
as well as hexadecimal string with and without "0x" prefix.
