790bad22c3 nvmf: add discovery controller ops
Simplify code that previously needed to check for subsystem type by
factoring out the discovery controller operations into a new ops
instance.

249a68e92b bdev: add API to claim block devices
Claim the block devices used by iSCSI LUNs and NVMe-oF subsystems so
they can't accidentally be reused.

This will also be used by virtual block devices to allow layering of
bdevs.

6ca517d460 nvmf: split subsystem lookup from host check
This allows us to print better error messages when connecting to a
subsystem that exists but does not allow a specific host.

Additionally, we can now return the correct error code for a host that
is not allowed.

9f2fc78e3f NVMf: Handle the memory leak issue of nvmf tgt
Reason: In acceptor_poller_unregistered_event, we
directly call spdk_nvmf_check_pools and spdk_app_stop,
it will fail the memory check.

And function nvmf_delete_subsystem_poller_unreg will
not be called since we already call spdk_app_stop.

c04b2968a6 nvmf: enforce NQN validity at creation time
Move the NQN validation into the subsytem creation function, and fix the
allowed size to match the spec.

The spec is not clear about the allowed NQN size; for now, interpret it
as 223 bytes, including the null terminator (222 bytes of actual NQN
plus one terminator byte).

5d8c94536a event: hide struct spdk_poller internals
This leaves more flexibility for future changes to the poller
representation without requiring API changes (after this one).

It also prevents the user from accidentally using poller fields in a
non-thread-safe way, since they can't be accessed directly anymore.
