Updated the patch on
<https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=198863>; with trim
and detach fixed there.  While I was at it, I also made some similar
changes on the boot/trim flags in 'configure' handling so it works
with old userland too.


Of course, it still throws errors up on the terminal when you try, but
then it goes ahead and does the stuff.  I sorta think that's
unnecessary, and maybe we oughta bypass gctl_get_paraml()'s error
spouting; in these cases it's not really fatal if the param isn't
there.  It does point up the being-out-of-sync, but I dunno if that's
worth bugging the user in such a roundabout way.

But either way, that's a whole different issue from just adding trim.
With the new patch, it should at least work with stuff unsync'd.  So,
where's the best place to hide out on the road and waylay a committer?
