The general style in sbin/nvmecontrol apppears to print uint64_t types
using %j, so I'm using that instead of the more general (but admittedly
ugly) PRIu64.
Add decoding of the Device Self-test log page and the ability to start
or abort a test.

local software base directory, as committed in SVN rev. 367813.
The pkg and mailwrapper programs used the LOCALBASE environment variable
for this purpose and this functionality is preserved by getlocalbase().
After this change, the value of the user.localbase sysctl variable is used
if present (and not overridden in the environment).
The nvmecontrol program gains support of a dynamic path to its plugin
directory with this update.

It seems *-passthru commands were broken from the day one, since the

The other three wrong argv[optind] instances are just in error messages.

Literal references to /usr/local exist in a large number of files in
the FreeBSD base system. Many are in contributed software, in configuration
files, or in the documentation, but 19 uses have been identified in C
source files or headers outside the contrib and sys/contrib directories.
This commit makes it possible to set _PATH_LOCALBASE in paths.h to use
a different prefix for locally installed software.
In order to avoid changes to openssh source files, LOCALBASE is passed to
the build via Makefiles under src/secure. While _PATH_LOCALBASE could have
been used here, there is precedent in the construction of the path used to
a xauth program which depends on the LOCALBASE value passed on the compiler
command line to select a non-default directory.
This could be changed in a later commit to make the openssh build
consistently use _PATH_LOCALBASE. It is considered out-of-scope for this
commit.

nvmecontrol tries to upload firmware in chunks as large as it thinks
the device permits. It fails to take into account the FWUG value used
by some drives to advertise the size and alignment limits for firmware
chunks.
- Use the firwmare update granularity value from the
- If the granularity is not reported or not restricted, fall back to
the previously existing logic that calculates the max transfer
size based on MDTS.
- Add firmware update granularity to the identify-controller output.

I recently made some bug fixes in nvmecontrol. It occurred to me that
since nvmecontrol lacks any kyua tests, I should convert the informal
testing I did into a more formal automated test. The test in this
change should be considered just a starting point; it is neither
complete nor thorough. While converting the test to ATF/kyua, I
discovered a small bug in nvmecontrol; the nvmecontrol devlist command
would always exit with an unsuccessful status. So I included the fix
for that, too, so that the test won't fail.

It allows to delete all user data from NVM subsystem in one of 3 methods.
It is a close equivalent of SCSI SANITIZE command of `camcontrol sanitize`,
so I tried to keep arguments as close as possible.
While there, fix supported sanitize methods reporting in `identify`.

While very useful by itself, it also makes `nvmecontrol` not depend on
hardcoded device names parsing, that in its turn makes simple to take
nvdX (and potentially any other) device names as arguments.
Also added IOCTL bypass from nvdX to respective nvmeYnsZ makes them
interchangeable for management purposes.

This adds several previously missed but important subcommands to list

just found with real testing to be broken subcommands.
Also while there, add possibility to explicitly specify nsid for

not having own devices, for example 0xffffffff, or just newly created

These are mostly compatible with Linux, with three exceptions.
1. We don't do metadata segment stuff. Our passthrough interface
doesn't cope. The code is there, but generates an error.
2. Linux lets you specify a namespace ID for the command. We current
do not: we get ours from the namespace device, or pass in a generic
one. Generally, this will lead to the same command, but FreeBSD's
is safer since you can't specify the wrong id.
3. --show-command outputs to stderr instead of stdout so you can both
see your command, and capture its output with a simple redirect.

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.
