This patch adds two macros, spdk_nvme_cpl_is_success and
spdk_nvme_cpl_is_pi_error. The former will be used to check if
checked read completes normally, and the latter will be used to
know if PI verification should be done.

divided into work in the host and target sides:
Host side: Add the TCP/IP transport in nvme lib (lib/nvme).
Target side: Add the TCP/IP transport in nvmf lib (lib/nvmf).

We can support up to 0.5 PB unmap requests by using the maximum number

sufficient for now.

Note that the name is "dataset_management" as opposed to

It's questionable whether "dataset" is valid English, but
it is best to match the specification.
