Renumber copyright clause 4

Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

mdoc(7): Use the new feature of the .In macro.

Change gethostname() to set errno to ENAMETOOLONG instead of ENOMEM
when the buffer is not long enough to hold the current host name.
POSIX does not standardize error returns for gethostname(), so it
doesn't matter which one we use, but ENAMETOOLONG is at least a little
more intuitive, and mi suggests the existence of prior art. I've been
running with this change for a while on my home machine with no
effect. At the same time, I've updated the prototype for
gethostname() to use the correct standard type (size_t) for the
namelen argument.

All of the in-tree callers fall into one of the following categories:
1) Call perror() or equivalent when gethostname() fails.
2) Ignore gethostname()'s return value entirely, potentially resulting
in data corruption if the buffer is too small.
3) Fall back to a (possibly sensible) default value if gethostname()
fails.

Many of the callers I examined shows signs of confusion about the
correct sizing of the host name buffer. gethostname(3) now has more
information about this, as well as updated standards information.

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.

Update a bunch of man pages to use .Fn instead

Correct a bunch of man page cross references and generally

ncurses, rpc, and some of the gnu stuff are still a big mess, however.
