Remove WWW entries moved into port Makefiles

Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.

This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.

Approved by:		portmgr (tcberner)

Add WWW entries to port Makefiles

It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.

Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.

There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.

Bump PORTREVISION for ports depending on the canonical version of GCC
as defined in Mk/bsd.default-versions.mk which has moved from GCC 8.3
to GCC 9.1 under most circumstances now after revision 507371.

This includes ports
 - with USE_GCC=yes or USE_GCC=any,
 - with USES=fortran,
 - using Mk/bsd.octave.mk which in turn features USES=fortran, and
 - with USES=compiler specifying openmp, nestedfct, c11, c++0x, c++11-lang,
   c++11-lib, c++14-lang, c++17-lang, or gcc-c++11-lib
plus, everything INDEX-11 shows with a dependency on lang/gcc9 now.

Bump PORTREVISION for ports depending on the canonical version of GCC
in the ports tree (via Mk/bsd.default-versions.mk and lang/gcc) which
has now moved from GCC 6 to GCC 7 by default.

This includes ports
 - featuring USE_GCC=yes or USE_GCC=any,
 - featuring USES=fortran,
 - using Mk/bsd.octave.mk which in turn features USES=fortran, and those
 - with USES=compiler specifying one of openmp, nestedfct, c11, c++0x,

Re-try ports affected by bug 193528 on powerpc* after r449590

For ports that are marked BROKEN on armv6, and also fail to build on
armv7, mark them so.

This is part two of a multipart commit to bring armv7 ports to parity
with armv6.

Remove BROKEN_FreeBSD_9

Approved by:	portmgr (blanket)

Libopencad is a library written in C++11, which provides a way to
read/write CAD  (DWG/DXF/DXFB) files. It was designed to have a
uniformal API to work with any CAD files.

It has a base class - CADFile.

Inheriting this class it's possible to create a driver for any CAD
format, all you need to do - is to overwrite interface functions
like GetGeometry(index), and others.

Now it has an implementation for DWG2000 (R15), but only for read.

Library comes with cadinfo utility, which prints out everything
library can get from file - header variables, CAD custom classes,
presented layers and geometries with their attributes.
