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.

You are trapped in the CAVEZ of PHEAR, your mission is to escape
through all the caves and make it out alive. To escape through a
cave you will have to find all the diamonds located in it. Once
you've found all the diamonds, their powers combined will help you
get to the next cave, one step closer to freedom.

CAVEZ of PHEAR is a Boulder Dash / Digger-like game game for
consoles/terminals with built in level editor.

Remove # $FreeBSD$ from Makefiles.

Extend expiration of ports broken with -fno-common

Extend the expiration of unmaintained leaf ports that are broken with
-fno-common and previously had a short expiration date.  The new date is set
to 2021-04-01, meaning the ports will be in the 2021Q2 branch, giving people
until 2021-06-30 (10 months from now) to fix issues.
Improve the wording of the deprecation message, mentioning both llvm 11 and
-fno-common.
Bump portrevision to force reinstall.  This way the warning message about
deprecation will be displayed to users installing or reinstalling the
software.
