Shuhei Matsumoto 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.
