8f92938fab Use proper variable for device path.
It seems *-passthru commands were broken from the day one, since the
device path is fetched into opt.dev variable and not left in argv[optind].
The other three wrong argv[optind] instances are just in error messages.

5458a1c840 Allow namespace-id specification where it makes sense.
It makes tool more convenient to not require user to explicitly convert
namespace device name into controller device name.  There should be no
changes to already existing syntaxes.

6995fb5eb7 Fix various Coverity-detected errors in nvmecontrol
This fixes several Coverity-detected errors in nvmecontrol. While in
here, a couple additional errors with shift/mask confusion that were
not diagnosed by Coverity are also fixed.

CIDs addressed: 1040299, 1040300, 1403972, 1403973, 1403985, 1403988,
1403990, 1404374, 1404427, 1404469, 1404510, 1404534, 1418118

CID 1403657 (resource leak of shared library handle) was marked
"intentional" in the Coverity scan database.

f634b4c1be Create generic command / arg parsing routines
Create a set of routines and structures to hold the data for the args
for a command. Use them to generate help and to parse args. Convert
all the current commands over to the new format. "comnd" is a hat-tip
to the TOPS-20 %COMND JSYS that (very) loosely inspired much of the
subsequent command line notions in the industry, but this is far
simpler (the %COMND man page is longer than this code) and not in the
kernel... Also, it implements today's de-facto
	command [verb]+ [opts]* [args]*
format rather than the old, archaic TOPS-20 command format :)

This is a snapshot of a work in progress to get the nvme passthru
stuff committed. In time it will become a private library and used
by some other programs in the tree that conform to the above pattern.

0d095c23a0 Const poison the command interface
Make the pointers we pass into the commands const, also make the
linker set mirrors const.

d4fdb249f2 Usage cleanup pt 2
Eliminage redundant spaces and nvmecontrol at start of all the usage
strings. Update the usage printing code to add them back when
presenting to the user. Allow multi-line usage messages and print
proper leading spaces for lines starting with a space.

7d923c13d7 Usage cleanup pt 1
Provide a usage() function that takes a struct nvme_function pointer
and produces a usage mssage. Eliminate all now-redundant usage
functions. Propigate the new argument through the program as needed.
Use common routine to print usage.

a13a291adf Move nvmecontrol to using linker sets for commands
More commands will be added to nvmecontrol. Also, there will be a few
more vendor commands (some of which may need to remain private to
companies writing them). The first step on that journey is to move to
using linker sets to dispatch commands. The next step will be using
dlopen to bring in the .so's that have the command that might need
to remain private for seamless integration.

Similar changes to this will be needed for vendor specific log pages.

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.

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.

d2cdb28b6f Ensure that a device node is specified when invoking the identify or reset
commands.

Also improve the checking of device node names, so that better error
messages are displayed when incorrect names are specified.
