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.

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.

One more small cleanup, forgotten yesterday.

Update to 0.86

Remove iconv(), iconv_open() and iconv_close() symbols from libiconv.

These were FreeBSD specific aliases for libiconv(), libiconv_open() and
libiconv_close() that are now also provided by libc which complicates
writing configure tests that work correctly when both libc iconv and
libiconv are available.

Also, because the libiconv iconv.h header redefines iconv* to libiconv*
correct use of the header implies that the aliases aren't used.

The following ports needed fixes because there was something wrong with
the way they tried to detect or use iconv:

audio/deadbeef: Remove LIBICONV_PLUG from a source file.  It's a
compile-time option and should not be set in source code.

converters/libiconv:
- Remove const qualifier from iconv(3) to match POSIX:
  http://pubs.opengroup.org/onlinepubs/9699919799/functions/iconv.html
- Patch iconv.h to expose more GNU extensions when LIBICONV_PLUG is
  defined because the base system iconv supports these extensions too.

Add/remove patches to/from ports to call iconv with non-const arguments.

This breaks some ports on FreeBSD 10 because base system iconv.h still has
the const qualifier.  Fix this by letting USES=iconv add a build dependency
on converters/libiconv so ports can use its iconv.h (with LIBICONV_PLUG
defined) instead of the base system iconv.h.

This exposed some ports that link with libiconv when it is available instead
of using libc iconv.  In these cases one of the following changes has been
