NVMe over Fabrics defines its own NVMe Qualified Name (NQN) format; it
does not use iSCSI Qualified Names.
Also change the default node base for nvmf_tgt to "nqn.2016-06.io.spdk".

The function call of spdk_nvmf_check_pools can be
directly put in nvmf.c.
Reason: This pool is created by nvmf subsystem,
it should be recycled by this subsystem.

The mempool functionality is never used at runtime - all bounce buffers
were immediately assigned to a rx_desc.

The RDMA tx_desc and rx_desc pools were only used at startup; all
descriptors are immediately allocated and put into a queue, and the
mempool functionality was never used at runtime.

Only move nvmf_request definitions from nvmf_internal.h
for now. Subsequent patches will move more.

Fabric commands were skipping a step, so unify all
types of requests through the same completion path.

The nvmf_request structure holds the pair of pointers
for rx_desc and tx_desc.

This moves some definitions from nvmf_spec.h to
nvme_spec.h based on the latest publication.

It is always set to nvmf_process_async_completion and is only used
within the library.
Also rename nvmf_process_async_completion to spdk_nvmf_request_complete
to clarify its purpose.

The pending type can be determined based on the command opcode.
This also moves the "issue pending RDMA reads" case out of the I/O queue
handling into the generic continuation code; this should not make any
difference for the current case, since the Fabrics Connect command is
the only other continuation case currently, and there cannot be any
pending RDMA reads in that case.

Keep a pointer to the local bounce buffer in the transport-agnostic
struct nvmf_request rather than groveling in tx_desc/rx_desc to get it.

This field is used to decide whether data needs to be transferred back
to the host after a command is completed.
Previously, this was determined using the length field, and length was
cleared to 0 after a transfer was completed. However, length will be
used in future patches after a host to controller transfer completes, so
we need some other way to tell what kind of data transfer is required.
