This patch make the function spdk_scsi_task_process_null_lun() as public and
finish the task immediately once we get task in iscsi layer.

The function spdk_iscsi_transfer_in will handle the task if the
status is not SPDK_SCSI_STATUS_GOOD.

When we enabled the ERL1 configuation, for the DATAIN task release
process, we will queue the task to the SNACK list firstly, and then
remove the list when got ACK from initiator, but for this part of
logic, the reference count of primary task was not released correctly.

The SPDK_TRACELOG macro depends on a CONFIG setting (DEBUG), so it
should not be part of the public API.
Create a new include/spdk_internal directory for headers that should
only be used within SPDK, not exported for public use.

Remove usage of the conf structs so they can be moved out of the public

This patch is preparation for fixing alloc_len overrun in SENSE 6/10 and
READCAP 6/10. To simplify code forbid usage of iov outside of
scsi/task.c.
This also drop SPDK_SCSI_TASK_ALLOC_BUFFER flag that obfuscate code. As
a replacement assume that if field alloc_len is non zero it mean that
iov.buffer is internally allocated. Functions
spdk_scsi_task_free_data(), spdk_scsi_task_set_data() and
spdk_scsi_task_alloc_data() manage this field.

This removes the 2 bytes of SenseLength from the beginning of the SCSI
sense_data buffer, so now the offsets within sense.data match up to the
expected values from the SCSI spec.

This patch adds support for spdk_bdev_readv in scsi layer.
It also fixes write so that it uses multiple iov's instead of one.
Currently we should use only task->iov (for single vector operation)
or task->iovs (for multiple vector operations).

We already require the assert header from the C standard library,
so use that instead of RTE_VERIFY to further isolate DPDK
dependencies.

SPDK_NOTICELOG() can already do printf()-style formatting, so there is
no need to use snprintf() on a temporary buffer first.
