nvmecontrol: Implement telemetry-log command.

This produces the same data as the Linux nvme-cli 'nvme telemetry-log'
command. It extracts the telemetry log from drive. This is a variable
length log, so we read the first page and find out how much of the log
to grab. There's 3 levels of details available, and we grab the level of
detail specified on the command line.

nvmecontrol: New commands to support Fabrics hosts

- discover: Connects to a remote Discovery controller, fetches its
Discovery Log Page, and enumerates the remote controllers described
in the log page.

The -v option can be used to display the Identify Controller data
structure for the Discovery controller. This is only really useful
for debugging.

- connect: Connects to a remote I/O controller and establishes an
association of an admin queue and a single I/O queue. The
association is handed off to the in-kernel host to create a new
nvmeX device.

- connect-all: Connects to a Discovery controller and attempts to
create an association with each I/O controller enumerated in the
Discovery controller's Discovery Log Page.

- reconnect: Establishes a new association with a remote I/O
controller for an existing nvmeX device. This can be used to
restore access to a remote I/O controller after the loss of a prior
association due to a transport error, controller reboot, etc.

- disconnect: Deletes one or more nvmeX devices after detaching its
namespaces and terminating any active associations. The devices to
delete can be identified by either a nvmeX device name or the NQN of
the remote controller.

- disconnect-all: Deletes all active associations with remote
controllers.

Add a basic test for nvmecontrol

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.

While very useful by itself, it also makes `nvmecontrol` not depend on

Also added IOCTL bypass from nvdX to respective nvmeYnsZ makes them

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.
