Rename preconv and roff.7 to have a 'mandoc-' prefix.  This removes the
conflicts with textproc/groff and allows both packages to co-exist,
paving the way for mdocml to be used in the tools infrastructure as an
nroff replacement.

Bump PKGREVISION.
Updated textproc/mdocml to 1.12.0nb3
Adjust CONFLICTS with mdocml, versions after and including 1.12.0nb3
no longer conflict with this package.

Bump PKGREVISION.
Updated textproc/groff to 1.20.1nb11
Switch to textproc/mdocml as the tool replacement provider for 'nroff'.

The nroff tool is primarily used to generate catman pages, however there
were circular dependency issues with using groff as the provider, as it
has a large number of dependencies, some of which depend on nroff.

mdocml is much smaller, has fewer dependencies, is BSD licensed, and is
just as capable in nroff mode.
Don't build the unit tests under Mac OS X. The makefile tries to create an
empty ".a" file which fails and breaks the build.
bootstrap-mk-files-20130912: Fix catman pages on SunOS.

Introduce a modified bsd.own.mk on SunOS which enables MKCATPAGES by
default, and a modified bsd.man.mk which correctly installs catman
pages with a section suffix rather than a blanket '.0'.

This allows the SunOS man(1) to find the catman pages correctly.
Updated pkgtools/bootstrap-mk-files to 20130912
Introduce CATMAN_SECTION_SUFFIX which if set to 'yes' will ensure that
catman pages are installed with a suffix which matches their section
instead of the default '.0'.

Enable it by default on SunOS, which requires that particular layout.
Add CATMAN_SECTION_SUFFIX support.
+ aria2-1.18.0, autogen-5.18.1, etm2-2.2.0 [etm successor],
  opendnssec-1.4.2, skype-4.2, xterm-297.
Add USE_TOOLS+=nroff to packages which generate catman pages.
Use CATMAN_SECTION_SUFFIX in packages which perform their own catman
page installation.
Install the generated catman page if requested.

Bump PKGREVISION.
Updated mail/milter-regex to 1.7nb2
Restore the catman page installation.  This reverts the fix for PR#42533,
and ensures that the manual pages can now be read on SunOS, however it
should not affect HP-UX support as this package now pulls in nroff as a
tool to correctly generate the catman page.

Bump PKGREVISION.
Updated lang/f2c to 20100903nb1
