Mdoc Janitor:

* Fix hard sentence breaks.

* NOTE: devstat(9) requires more mdoc(7) work.

The devclass is an object type, mark it as such.
This also unbreaks the devclass_find(9) manpage.

Some mdoc(7) fixes:

Nuke incorrect usage of .Ar; replace it with .Vt, .Va or .Fa appropriately.
The .Ar mdoc(7) specifier should only be used when displaying command line
arguments.
