Previously, we used cap_lo and cap_hi to represent the 32-bit halves of
the full CAP register. However, it is simpler to keep them in a single
64-bit structure, and is no less efficient on 64-bit platforms.
Also name the NSSRS field from NVMe 1.2, which was previously reserved.

If the controller is failed, attempting to submit additional I/O is
futile - it will be immediately failed using the completion callback,
which can result in infinite recursion if the application code resubmits
I/Os on failure.
Instead, provide a way for request submission to indicate failure, and
use it to exit early if the controller is failed; this can only happen
when a reset failed (timed out).
If a request is submitted directly by the user when the controller has
failed, we can return an error code directly. For the case where I/O
was queued and is being resubmitted after a reset, we still need to call
the completion handler via _nvme_fail_request_ctrlr_failed().

Replace the previous code that allocated each tracker individually with
one large allocation per queue pair.
struct nvme_tracker is now explicitly padded to reach exactly 4096 bytes
to allow normal array indexing to work correctly while maintaining the
alignment requirement that ensures each tracker's PRP list does not
cross a page boundary.
This also allows removal of the act_tr array, since the tr array can be
indexed directly now, and each tracker can store its own active state.

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.

When multiple NVMe controllers are being initialized during
spdk_nvme_probe(), we can overlap the hardware resets of all controllers
to improve startup time.
Rewrite the initialization sequence as a polling function,
nvme_ctrlr_process_init(), that maintains a per-controller state machine
to determine which initialization step is underway. Each step also has
a timeout to ensure the process will terminate if the hardware is hung.
Currently, only the hardware reset (toggling of CC.EN and waiting for
CSTS.RDY) is done in parallel; the rest of initialization is done
sequentially in nvme_ctrlr_start() as before. These steps could also be
parallelized in a similar framework if measurements indicate that they
take a significant amount of time.
