Backed out r228904, and added libstdthreads support to mdoc(7) to where
it belongs.

Pull up vendor changes to mdoc(7)

This switches us to using -isoC-2011 as the symbol name which is used by
groff and mdocml. It follows the change to 4 digit years as done with
IEEE Std 1003 post-1999.

MFC after: 2 weeks (groff changes only)

Add libstdthreads.

This library implements the C11 threads interface on top of the pthreads
library. As discussed on the lists, the preferred way to implement
this, is as a separate library.

It is unlikely that these functions will be used a lot in the future. It
would have been easier if the C11 working group standardized (a subset
of) pthreads and clock_nanosleep(). Having it as a separate library
allows the embedded people to omit it from their system.

Discussed on: arch@, threads@

Add the C11 standard to groff. This allows us to refer to C11 as -isoC-11.

Pull up vendor changes to mdoc(7).

Update groff manpage and symbols with what has been submitted upstream.
Also remove local overrides that are now in the contrib tree.

This is a direct commit to contrib/ as we will no longer import any
newer groff snapshots, due to licensing issues.

: 2002-01-14 Ruslan Ermilov <ru@FreeBSD.org>
:
: * tmac/groff_mdoc.man: Minor fixes.

Print architecture right after an operating system name in a title.

From ChangeLog:

:
: * tmac/doc-common (Dt): Change output of architecture strings.
: Do some syntax cleanup.

:
: * tmac/doc.tmac (Ex): New implementation.

From ChangeLog:

: 2001-08-13 Ruslan Ermilov <ru@FreeBSD.org>
:
: * tmac/doc.tmac (Rv): Implement support for 0 or more than 1
: argument.
: * tmac/groff_tmac.man: Updated.

All of the following are now valid:

.Rv -std f1
.Rv -std f1 f2
.Rv -std f1 f2 f3
.Rv -std

The last form is useful where the standard return behavior is applicable
to all of the functions described in this particular manpage. Look, for
example, at the stat(2), setresuid(2), and utimes(2) manpages.

The form with >1 functions is useful in a mixed environment. See the
fhopen(2) manpage for an example.

From ChangeLog:

: 2001-07-18 Ruslan Ermilov <ru@FreeBSD.org>
:
: * tmac/groff_mdoc.man: Document new -width and -column syntax.
: Some other minor fixes.
: * tmac/an-old.tmac: Add `AT' and `UC' macros.

Import latest mdoc(7) fixes of mine.

Fold -xwidth functionality into -width. .Bl now tests whether
string immediately following a leading dot starts with a valid
macro name.

Added similar functionality to the -column list's column width
specifiers. For example, the following now works as expected:

.Bl -column ".Va hw.crusoe.percentage" ".Vt integer" "Changeable"
.It Sy "Name\tType\tChangeable\tDescription"
.It Va hw.crusoe.longrun Ta Vt integer Ta yes Ta "LongRun mode:"
.It Ta Ta Ta "0: minimum frequency mode"
.It Ta Ta Ta "1: power-saving mode"
.It Ta Ta Ta "2: performance mode"
.It Ta Ta Ta "3: maximum frequency mode"
.It Va hw.crusoe.frequency Ta Vt integer Ta no Ta "Current frequency (MHz)."
.It Va hw.crusoe.voltage Ta Vt integer Ta no Ta "Current voltage (mV)."
.It Va hw.crusoe.percentage Ta Vt integer Ta no Ta "Processing performance (%)."
.El

This is especially useful for groff devices with variable width
fonts, like -Tps or -TX100.
