Use the fancy .In macro for includes. From Jan Klemkow. ok jmc schwarze

Add getprogname() and setprogname() to ease slackers^porters' work.
Man page adapted from FreeBSD and NetBSD.

Bump libc minor now (there will be more upcoming changes).

input from tedu@

convert to new .Dd format;

- sync prototypes and header file excerpts to reality
- many grammar, punctuation, macro, layout, spelling/typos,
rewording, etc. fixes
- avoid first person
- sprinkle crossrefs where relevant

help & ok jmc

It's not that I mind split infinitives. I just like to save'em for when
they're really needed.

Clarify that the proctitle is set to "progname: fmt", not "progname:fmt".

Various repairs, mostly to get rid of short lines.

In the format string bug description under CAVEATS, clarify what we mean by
building the string ``by hand'' using a function like snprintf(); deraadt@ ok

Stronger caveat wrt stack smashing via % escapes. Each man page
carries the same caveat...

Add a CAVEATS section explaining that you should never pass a user-supplied
format string directly without %s.

- remove all trailing whitespace
* except when it is escaped with a `\' at the end of the line
- fix remaining .Nm usage as well
- this is from a patch I received from kwesterback@home.com, who has been
working on some scripts for fixing formatting errors in mdoc'd man pages

Ok, so there could be a cost/benefit debate with this commit, but since I have
the patch we might as well commit it...

remove extra comma from .Dd arguments: "Month ##, ####" is the correct format,
not "Month, ##, ####"
