Remove remnants of dev_t.

These functions take a `struct cdev *' -- not a dev_t. Inside the
kernel, dev_t has the same use as in userspace, namely to store a device
identifier.

Remove spurious .Fc which caused this manpage to be closed
prematurely.

of the typeset output, tend to make diffs harder to read and provide
bad examples for new-comers to mdoc.

Fixed bitrot in synopsis. Important interface changes hadn't reached here.

$Id$ -> $FreeBSD$

Add $Id$, to make it simpler for members of the translation teams to
track.

The $Id$ line is normally at the bottom of the main comment block in the
man page, separated from the rest of the manpage by an empty comment,
like so;

.\" $Id$
.\"

If the immediately preceding comment is a @(#) format ID marker than the
the $Id$ will line up underneath it with no intervening blank lines.
Otherwise, an additional blank line is inserted.
