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.

graphics/libsixel: Add CPE information

One more small cleanup, forgotten yesterday.
Reported by:	lwhsu

Remove # $FreeBSD$ from Makefiles.

Restore original (upstream) distfile URL.  During initial `make makesum'
the distfile got fetched from the nearby Gentoo mirror but I didn't pay
enough attention and didn't notice that:

    $ curl -sI
https://mirror.yandex.ru/gentoo-distfiles/distfiles/libsixel-1.8.6.tar.gz |
egrep HTTP\|Content-Length:
    HTTP/1.1 200 OK
    Content-Length: 4791628

Because both its size (previous distfile was 4778776 bytes) and contents
looked legit, I did not verify that it is identical to the file fetched
from GitHub directly.  Comparing their contents show only some missing
files and directories (example programs and sample image files, none of
them are built or installed anyway); the source code itself is identical
between the two, as well as resulting `include/sixel.h' file which now
comes pre-generated:

Temporarily switch download location to the distfile found on the mirrors
until I figure out what's going on.

USE_GITHUB: For the new support, fix DISTNAME to be more consistent.

When using GH_TAGNAME the DISTNAME would have GH_PROJECT and GH_ACCOUNT in
it. When not using GH_TAGNAME it would not have this. Now both cases
will add in the GH_PROJECT and GH_ACCOUNT.

Add special care to ensure that the DISTVERSION is not added in twice. If
a port does GH_TAGNAME=v${PORTVERSION} it will be added in twice though. For
that case DISTVERSIONPREFIX=v should be set and no GH_TAGNAME should be used.

empty() is used rather than (!defined || !${}) to support fmake.

The purpose of setting DISTNAME at all in these cases is to make it more clear
that the distfile is from *GITHUB* and to avoid collisions if a project were
to be renamed or moved. Without adding in GH_PROJECT and GH_ACCOUNT then there
are real risks that collisions on filenames would happen on renamed or moved
projects, which is fairly common. A GITHUB-generated file may not match
a custom-rolled or git-archive-rolled distfile.

This package provides encoder/decoder implementation for DEC SIXEL graphics,
and some converter programs.
SIXEL is one of image formats for terminal imaging introduced by DEC VT series.
Its data scheme is represented as a terminal-friendly escape sequence.
So if you want to view a SIXEL image file, all you have to do is "cat" it to
your terminal.
