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.

dns/wdns: Upgrade to version 0.11.0

  * Improve support for CAA records. (CAA was previously rendered as a
    "generic" rdata type.)

  * Bug fix for NSEC/NSEC3/CSYNC: do not output empty rrtype bitmaps
    per RFC6840 section 6.4.

  * Fix parsing of A6 records that ommit and address portion. Correct
    parsing of A6 records with prefix length 0. Correct handling of
    A6 address bytes. The address bytes of an A6 record are an address
    suffix relative to the prefix represented by the domain name, and
    so must be copied to and from the lower order bytes of the internal
    address representation. These A6 code updates were for the purposes
    of clearing "round trip" test errors in the existing code base.

dns/dnstable-convert: Upgrade to version 0.11.0

dnstable-convert 0.11.0:

  * Add new tool dnstable_unconvert which converts the RRSET entries of
    a dnstable file to the equivalent NMSG format.

  * Add SVCB and HTTPS records indexing support, based upon
    draft-ietf-dnsop-svcb-https-07. Note that the hostname portion in
    the RDATA is downcased in the sliced encoding and reversed name
    entry.

  * Put CDS, CDNSKEY, and TA resource record types into dnssec.*
    output files. To duplicate these three DNSSEC types to the dns.*
    output files for compatibility, use the new dnstable_convert -D

net/nmsg: upgrade to version 1.0.0

  The network encapsulation library, nmsg, version 1.0.0 is released.
  This release deprecates Crossroads I/O (libxs) support in favor of
  ZeroMQ (libzmq). Note command-line updates enabling ZeroMQ socket
  connections for nmsgtool, as described in its man page. In addition
  the treatment of unknown rrtypes was amended for nmsgtool JSON
  output. In detail:

    Replace libXS with ZeroMQ and associated calls.

    Developer API functions nmsg_input_open_xs(),
    nmsg_input_open_xs_endpoint(), nmsg_io_add_input_xs_channel(),
    nmsg_output_open_xs(), and nmsg_output_open_xs_endpoint() are
    deprecated and replaced with respectively: nmsg_input_open_zmq(),

One more small cleanup, forgotten yesterday.

Remove # $FreeBSD$ from Makefiles.

New port dns/dnstable_convert.  It was split out of dnstable to reduce the
dependencies of dnstable.

dnstable_convert is a conversion utility for passive DNS data in
dnstable format.
