Check whether the cgd device selected is available to be
configured,that is, not already in use, before requesting
passwords from the user (or elsewhere).

Fix usage for rump.   Fixes test breakage caused by previous commit.
Check arg count in configure() at entry, rather than later.

This avoids the stupid null deref I added a couple of commits
ago (on bad usage) and also simplifies the rest of the routine
which no longer needs to check the arg count nearly as much.
Thanks to Alexander Nasonov for finding the null deref bug.

Fix missing -p in usage message (noted by Christoph Badura, thanks),
and update -l usage as well.
While here fix man page synopses and a few other odds and ends.
Add commas in enumeration.
