man pages: add missing commas between subordinate and main clauses

jmc@ dislikes a comma before "then" in a conditional, so leave those
untouched.

sleep.3: miscellanous cleanup, rewrites

Highlights:

- Tighten up the NAME.
- "process" -> "thread".
- Tidy up the DESCRIPTION. In particular, omit discussion of the
historial SIGALRM-based implementation.
- Simplify RETURN VALUES.
- Add an ERRORS section, note that sleep(3) can set EINTR.
- Update STANDARDS to POSIX.1-2008.
- Note that setting errno is an extension to the spec.

Discussed with and revised by jmc@, deraadt@, millert@, and schwarze@.
With a history lesson from jsg@.

correct Research Unix edition "appeared in" use in HISTORY

Starting from "Combined Table of Contents" in Doug McIlroy's
"A Research UNIX Reader" a table of which edition manuals appeared in.
Checked against manuals from bitsavers/TUHS and source from TUHS where
available.

Ingo points out there are cases where something is included but not
documented until a later release.
bcd(6) v6 v7
printf(3) v2 v4
abort(3) v5 v6
system(3) v6 v7
fmod(3) v5 v6

ok schwarze@

remove section 2/3 pointers from section 1,
and do not point programmers at the obsolete usleep(3);
based on a diff from Jan Klemkow <j dot klemkow at wemelug dot de>,
but removing more as suggested by jmc@ and deraadt@

HISTORY; tweaks and ok sobrado@ jmc@

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

Make sleep(3) and usleep(3) more consistent and remove extraneous
historic implementation details that get in the way of readability.
Our usleep(3) does not return EINVAL for values >= 1,000,000 but
still mention it in CAVEATS since some do.
Portions adapted from FreeBSD. OK jmc@

some SEE ALSO additions from Ingo Schwarze;

convert to new .Dd format;

Remove the advertising clause in the UCB license which Berkeley
rescinded 22 July 1999. Proofed by myself and Theo.

Repairs, mostly removing hard sentence breaks.

Consistify naming of RETURN VALUES section.

- 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...

added select(2) to see also, mostly to test cvs commit
