NVMe opcodes contain a two-bit field that encodes the expected data
direction for each command. Add an enum and a function to extract these
bits.

Only 65535 I/O queues are allowed, not 65536.
Each I/O queue must have a unique queue ID, and since queue ID 0 is
reserved for the admin queue, there can be only 65535 unique I/O queue
IDs.

nvme_spec.h already has a structure with the correct bitfields for the
CSTS register, so use it in struct spdk_nvme_registers.

Also add a space between Copyright and (c).
The copyright year can be determined using git metadata.
Also remove the duplicated "All rights reserved." - every instance of
this line already has a corresponding "All rights reserved" immediately
below it, except for examples/ioat/kperf/kmod/dma_perf.c, where I have
added it manually.
Performed using this command:
git ls-files | xargs sed -i -e 's/Copyright(c) \(.*\) Intel Corporation. All rights reserved./Copyright (c) Intel Corporation./'

A namespace indicates support for reservations by reporting a non-zero
value in the Reservation Capabilities field in the Identify Namespace
data structure, and controller indicates support for reservation in the
Identify Controller data structure, Here we used namespace field as the
support flag.
