0d787e9b35 NVMe: Add big-endian support
Remove bitfields from defined structures as they are not portable.
Instead use shift and mask macros in the driver and nvmecontrol application.

NVMe is now working on powerpc64 host.

1de7b4b805 various: general adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

No functional change intended.

efa2980530 For "nvmecontrol devlist", show namespace sizes in terms of MB instead of
GB to improve granularity of the reporting - especially for namespaces
that are on the order of 1 or 2 GB.

38441bd9a9 Add message when nvd disks are attached and detached.
As part of this commit, add an nvme_strvis() function which borrows
heavily from cam_strvis().  This will allow stripping of
leading/trailing whitespace and also handle unprintable characters
in model/serial numbers.  This function goes into a new nvme_util.c
file which is used by both the driver and nvmecontrol.

2fb37e8f1a Fix nvme(4) and nvd(4) to support non 512-byte sector sizes.
Recent testing with QEMU that has variable sector size support for
NVMe uncovered some of these issues.  Chatham prototype boards supported
only 512 byte sectors.

dddb618e3f Use _PATH_DEV (from paths.h) for the "/dev/" string, rather than
hard-coding it.

b378da2781 Simplify open_dev() by returning errno values rather than just 0 or 1.
Also remove stat() call and just rely on errno from open() call to discern
whether dev node exists or not.

e8f25c6266 Define constants for the lengths of the serial number, model number
and firmware revision in the controller's identify structure.

Also modify consumers of these fields to ensure they only use the
specified number of bytes for their respective fields.

821ef73ca6 Incorporate feedback from bde@ based on r252672 changes:
* Use 0/1 instead of sysexits.  Man pages are confusing on this topic,
  but 0/1 is sufficient for nvmecontrol.
* Use err function family where possible instead of fprintf/exit.
* Fix some typing errors.
* Clean up some error message inconsistencies.

6420873cd6 Create #defines for NVME_CTRLR_PREFIX and NVME_NS_PREFIX for the "nvme"
and "ns" strings, rather than hardcoding the string values throughout the
nvmecontrol code base.
