rS329092: Add a deprecation warning when using the feature which mounts devices

Summary

While this feature is long standing, it is undocumented, fails to
follow the unix philosophy, and is easily scripted.

The warning will be merged to FreeBSD 11 along with recent improvemnts
and the feature will be removed from HEAD before FreeBSD 12.

264 ↗	(On Diff #22934)	Why not move this much earlier after `if (S_ISCHR())`?

Move the warning earlier and use xo_warnx().

LGTM, however, this made me realize that the #ifdef MOUNT_CHAR_DEVS is actually in the wrong place (I think).

If (mntpt = getmntpt(*argv)) != NULL, the device is already mounted and we fall out the bottom and stat normally. So the #ifdef should only cover the == NULL part. (I think the #endif may actually be in the right place, just the #if is misplaced.)

Correct the location of MOUNT_CHAR_DEVS and emit better errors.

I hate to see more libxo enter programs, but the functional change looks good.

I reported on this deprecated element core dumping ( https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=237368 )

As it was scheduled to be removed before 12 away, maybe it could be actioned now?

Cheers
