Parses and verifies hexadecimal cpu bit mask specified by the user.
Added verification to check for cpu cores range, making sure poll groups cores
assigned within the range of cpu cores allocated for the application.
RPC nvmf_set_config now takes an argument to configure ‘poll groups’,
a new parameter for NVMf subsystem. This parameter sets a CPU mask
to spawn threads which run an event loop for a ‘poll group’.

If ctrlr supports ANA log page, nvme_ctrlr allocates a buffer for ANA
log page and read ANA log page itself, and then each nvme_ns sets its
ANA state by parsing ANA log page.
Most code was brought from NVMe driver because NVMe driver already
supports ANA log page management. However it had a bug that assumed
each descriptor is 8-bytes aligned. Fix the bug together in this
patch. Besides, the implementation in NVMe driver was synchronous.
NVMe bdev module reads ANA log page asynchronously instead.
The next patch will support ANA log page update by AER handler.

When entering the if case to order the list, there is bug should be
fixed. The original code does not address this.
The way this happens is when there is a connection left in the socks_with_data list
between polls and there are enough new events detected that it would exceed the
maximal number of events. A connection is left on this list between polls if it isn't
fully drained via reads by the upper layer on each poll loop.
Currently, the maximal socket event num is 32. Then we did not hit this issue
in our normal test cases. But when you use NVMe-oF tcp target to test which is
described in #2105, there are more than 32 active sockets, and it exceeeds
the maximal num of events of polling (32), so we will trigger this issue.

Recent work identified race conditions having to do with the
dynamic flow control mechanism for the idxd engine. In order
to both address the issue and simplify the code a new scheme
is now in place. Essentially every DSA device will be allowed
to accomodate 8 channels and each channel will get a fixed 1/8
the number of work queue entries regardless of how many
channels there are. Assignment of channels to devices is round
robin and if/when no more channels can be accommodated the get
channel request will fail.
The performance tests also revealed another issue that was
masked before, it's a one-line so is in this patch for convenience.
In the idxd poller we limit the number of completions allowed
during one run to avoid the poller thread from starving other
threads since as operations complete on this thread they are
immediately replaced up to the limit for the channel.

In uring_sock_create(), we loops through all the addresses available.
If something is wrong, we should close(fd) and set fd to -1, and
try the next address. Only, when one fd satisfies all conditions,
we will break the loop with the useful fd.

The reference count of nvme_bdev_ctrlr will be used to update ANA log
page safely, and nvme_bdev_ctrlr_destruct() can be used to decrement
reference count after completing ANA log page update.
However, nvme_bdev_ctrlr_destruct() is not a good name for this case.
Furthermore, nvme_bdev_ctrlr_destruct() does not set the destruct flag
to true, and the next patch will need nvme_bdev_ctrlr_acquire().
Hence rename nvme_bdev_ctrlr_destruct() by nvme_bdev_ctrlr_release().

Factor out registering nvme_bdev_ctrlr as io_device and populating
namespaces after creating nvme_bdev_ctrlr into a helper function.
We extract spdk_io_device_register() from nvme_bdev_ctrlr_create()
because free(NULL) is correct but spdk_io_device_unregister(NULL) is
not allowed, and hence it is very simple if we call spdk_io_device_register()
only after nvme_bdev_ctrlr is successfully created.

Reorder a few operations and increment nvme_bdev_ctrlr->num_ns
after allocating nvme_bdev_ctrlr->namespaces[i] successfully.
Then unify the goto label for error cases to err and the err label
simply calls nvme_bdev_ctrlr_delete().
There is one noticeable change in this patch. Previously the
controller had not been detached when creating nvme_bdev_ctrlr failed.
However, after this patch, the controller will be detached when creating
nvme_bdev_ctrlr failed. This will be reasonable change.

spdk_nvmf_subsystem_state). This allows us to
