reserved for the admin queue, there can be only 65535 unique I/O queue

The automated test systems will catch any issues that would
theoretically be missed by contributors compiling with old

cf0871a57e ioat: make channel allocation explicit
Add a parameter to each I/OAT library function that requires a channel
instead of implicitly using the thread-local channel registration model.

I/OAT channels are already reported by the spdk_ioat_probe() attach
callback, so no infrastructure for channel allocation is necessary.

3272320c73 nvme: make I/O queue allocation explicit
The previous method for registering I/O queues did not allow the user
to specify queue priority for weighted round robin arbitration, and it
limited the application to one queue per controller per thread.

Change the API to require explicit allocation of each queue for each
controller using the new function spdk_nvme_ctrlr_alloc_io_qpair().

Each function that submits a command on an I/O queue now takes an
explicit qpair parameter rather than implicitly using the thread-local
queue.

This also allows the application to allocate different numbers of
threads per controller; previously, the number of queues was capped at
the smallest value supported by any attached controller.

Weighted round robin arbitration is not supported yet; additional
changes to the controller startup process are required to enable
alternate arbitration methods.

5dafa4940f nvme.h: include stdbool.h and stdint.h
Explicitly include system headers for types that are used in public
headers.

These were being pulled in by example code, so SPDK itself would build,
but other apps that did not include stdbool.h would fail to compile when
including spdk/nvme.h.

Also include nvme.h first in nvme_internal.h so this case gets tested
during normal compilation.

8374a727a9 nvme: refactor nvme_attach() into nvme_probe()
The new probing API will find all NVMe devices on the system and ask the
caller whether to attach to each one.  The caller will then receive a
callback once each controller has finished initializing and has been
attached to the driver.

This will enable cleanup of the PCI abstraction layer (enabling us to
use DPDK PCI functionality) as well as allowing future work on parallel
NVMe controller startup and PCIe hotplug support.
