The SPDX folks have obsoleted the BSD-2-Clause-FreeBSD identifier. Catch
up to that fact and revert to their recommended match of BSD-2-Clause.

Report status from dword0 for passthru commands. Many commands report
some status or information here, so reporting it can help know what's
going on.

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.

I merged passthru.c from the wrong branch (it was a branch that went further in
a direction I wound up not taking). Fix the mismerge and turn passthru on.
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.
