Hide the implementation details about multiple threading libraries
from the synopses of pthread*(3) manpages.

Reviewed by: deischen, davidxu

Document that EPERM is returned when the calling thread does not have
the mutex locked. Also tweak the wording to make it more consistant
between pthread_cond_wait and pthread_cond_tiedwait.

Confirmed with the opengroup's web site that this is a valid return
value. Wording used specifically not that of opengroup's online man
pages.

mdoc(7) police: split punctuation characters + misc fixes.

Introduce .Lb macro to libc_r manpages.

Remove single-space hard sentence breaks. These degrade the quality
of the typeset output, tend to make diffs harder to read and provide
bad examples for new-comers to mdoc.

$Id$ -> $FreeBSD$

Fix EINVAL related descriptions.

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.

I've put together man pages for the pthread_cleanup, pthread_cond, and
pthread_mutex routines. I've also tweaked pthread_create.3 to point to
pthread_cleanup_push(3) and pthread_cleanup_pop(3).
