Currently cpumask cannot be specified for each portal when it is
created by JSON-RPC and portal group creation is not unified
between iSCSI.conf and JSON-RPC.
This patch does the following:
- cpumask string is decoded in spdk_iscsi_portal_create() which
is common between iSCSI.conf and JSON-RPC.
- parsing configline of portal is difficult to understand and
hence it is refactored.
- UT code is added.
JSON-RPC will be added by the next patch.

For I/O that do not span a cluster boundary, just issue
a single batch command to underlying block device.
For I/O that do span a cluster boundary, issue a batch
command for each against the blob (not the block device)
for each cluster accessed by the I/O.
This is all in preparation for upcoming patches which
enable thin provisioning and hence cluster allocation
in the I/O path. It will simplify implementation of
the cluster allocation path since now that code only
needs to be concerned with a single allocation at once.
Splitting for readv/writev will be handled in a
later patch.

This breaks out the logic for building a batch for
non-iov operations to a separate function. Future
patches will do further modifications on this
new function - separating it out into two separate
functions, one for operations that span a cluster boundary
and one for those that do not.
No functional change here - this is just moving code
around to reduce size of upcoming patches.

When there are two bdevs built on the same io_device,
it is possible that one bdev entirely saturates
underlying queue, not letting the second bdev issue
a single I/O. The second bdev will silently fail any
subsequent I/O and append it to the nomem_io list.
However, since we resend I/O only from I/O completion
callback and there's no outstanding I/O for that bdev
(io_outstanding==0), the I/O will never be resent.
It'll be stuck in nomem_io forever.
This patch makes nomem_io list to be shared between
bdevs built on the same device. It is now possible
that I/O completion callback from one bdev will retry
sending I/O from other bdev.
The shared bdev data is based on thread-local
bdev_mgmt_channel, so doesn't need any external
synchronization.

bdev hotremove event is send directly to hotremove callback given
during spdk_scsi_dev_construct() call. So any bdev hotremove might be
promoted to whole SCSI device removal (like in vhost) wich will trigger
LUN removal. But after returning from hotremove callback LUN and device
might be still referenced (eg to register poller or by outstanding IO).
Even worse: spdk_scsi_dev object is not dynamicaly allocated but
returned from static array which mean there is no way to detect
use-after-free error on spdk_scsi_dev by any tool. This might lead to
using SCSI device that is freed or assigned to different device.
To fix this:
- always delete LUN using hotremove path
- defer spdk_scsi_dev delete/removal after all LUNS are really
deleted.

temporarily put in this queue just to be moved
out of it yet within the same reactor cycle.

The NVMe spec states that nqn names are to be encoded in utf-8. The
prefixes of all nqn's are already required to be ascii by virtue of
their structure so they are already valid utf-8, but the user specified
strings should be checked for valid utf-8 strings.

When trying to create a scsi dev with inexistent
lun (bdev name), the scsi_dev_construct would
just return a NULL without printing any error.
We should probably return an error code of some
kind, but for now let's just print an extra
message.

This is more efficient and buf_link users don't
need the extra flexibility that TAILQ provides.
link could also be changed to an STAILQ, but its usage
is not in the performance path so not touching that
as part of this commit.

Purpose: If the qp creates in a failure state,
we should set cm_id = NULL, then we do not need to
destroy the qp which is not created.
Also this patch add return value check while calling
spdk_nvmf_rdma_qpair_initialize.
