When zcero copy send is enabled and used by initiator,
it could significantly increase latency in some payloads.
To enable more fine graing configuration of zero copy
send feature, add new parameters enable_zerocopy_send_server
and enable_zerocopy_send_client to spdk_sock_impl_opts to
enable/disable zcopy for specific type of sockets.
Exisiting enable_zerocopy_send parameter affects all types
of sockets.

On host side the connections are created and then added to thread's
poll group. Those connections could use different NIC queues underneath.
To route all connections of poll group through single queue a unique
placement id is chosen as group_placement_id and each socket of poll
group is marked with group_placment_id using getsockopt(SO_MARK) option.
The driver could use so_mark value of skb to determine the queue to use.

suppression
When all of the following conditions are met:
- non-blocking socket
- zero copy is enabled
- interrupts are suppressed (i.e. busy polling)
- NIC tx queue is full at the time sendmsg() is called
- epoll_wait sees there is already an EPOLLIN event
then we can get into a situation where data we've sent is queued
up in the kernel network stack, but interrupts have been suppressed
because other traffic is flowing. This makes the kernel miss the
signal to flush the software tx queue. If there wasn't also already
a pending EPOLLIN event, then epoll_wait would have been sufficient
to kick the system out of this state. But when all of this aligns,
it hangs.
We deal with this by detecting the scenario and calling poll(), which
will force the kernel to issue the pending transmits.

However OCSSD namespace had used nvme_ns->populated to free resource

The nvme_ns->ref was added to nvme_bdev_ns to support both multipath
and OCSSD range. OCSSD range was to split a namespace into multiple
partitions.
However, OCSSD range was not used and removed to simplify multipath.
When namespace is not split, nvme_ns->ref is 2 at the maximum. First is
for populating namespace and second is for nvme_bdev. nvme_ns->populated
is for populating namespace and nvme_ns->bdev is for nvme_bdev.
Hence we can use nvme_ns->populated and nvme_ns->bdev directly instead of
nvme_ns->ref.
A few patches from this remove nvme_ns->ref and use nvme_ns->populated
and nvme_ns->bdev instead.
dThis patch inlines nvme_bdev_ns_detach() into the callers and remove it.
The following patches will adjust the locations to update nvme_ns->populated

Removing nvme_ns->ref will be helpful to associate multiple namespaces

nvme_bdev_ns_to_bdev() was introduced because nvme_ns->bdev may be
removed to support multipath. However, it is unlikely now.
Hence it is easier to read to stop using nvme_bdev_ns_to_bdev() and
access nvme_ns->bdev directly.

Clean up bdev_nvme_add_trid() by factoring out comparison of namespaces
and comparison of trids into helper functions, bdev_nvme_compare_namespaces()
and bdev_nvme_compare_trids(), respectively.
Then rename bdev_nvme_add_trid() by bdev_nvme_add_secondary_trid().
Rename is for clarification and clean-up is for the next patch.
The next patch will merge spdk_nvme_detach() and populate_namespaces_cb()
into the renamed bdev_nvme_secondary_trid(). Clean-up makes the
next patch simpler.
One note is that checking if the type of trid is not PCIe is done
by holding mutex now to prioritize clean up.

The API spdk_nvme_ctrlr_free_io_qpair() returns immediately if the
passed qpair is NULL, but calling spdk_nvme_ctrlr_free_io_qpair()
with NULL should be avoided.
This patch cleans up the code to ensure that nvme_ch->qpair is NULL if
disconnected and spdk_nvme_ctrlr_free_io_qpair() is called only if
nvme_ch->qpair is not NULL.
Then add a test scenario that two reset requests were submitted
simultaneously and the first reset request failed and then the second
reset request also failed. This verifies the refactoring done in the
next patch.

Add support for zoned namespaces in the bdev/nvme module.
Query the namespace type, and if a zoned namespace is found, set the
bdev struct members needed by the bdev_zone.h APIs.
Note that while vbdev_zone_block and bdev_ocssd have zone locks,
bdev/nvme does not need any kind of zone lock, because NVMe ZNS
supports append natively.
The whole point of the zone append command is that you don't need any
locks, even when having multiple writers, since the drive will return
back the Assigned LBA where the blocks were actually written.
If a SPDK application will utilize writes instead of zone appends,
the SPDK application itself will need a per zone lock in order to
make sure that there is only one outstanding write.
Adding zone locks in bdev/nvme would reduce the performance of zone
appends, for no reason at all.
