This will allow removal notifications to be propagated to the library
user (e.g. for hotplug).
The callback is currently unused, but this at least prepares the API for
the future hotplug support.

Previously, there was no way to determine what namespace ID was assigned
when a namespace was created via the NVMe library interface.
Also drop the incorrect comment about calling
spdk_nvme_ctrlr_process_admin_completions(), since
spdk_nvme_ctrlr_create_ns() checks the admin queue internally.

Provide a new structure, spdk_nvme_ctrlr_opts, to let the user modify
the default controller initialization options during probe/attach.
Currently, only the number of queue pairs can be modified in this way;
other options will be added later.

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.

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.
