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.

cleanup: remove trailing whitepaces

archivers: remove 'Created by' lines

Fix CONFLICTS entries in archivers, astro, audio

Fix conflicts entries based on a script that searches for duplicate
files installed by several ports.

Some patters seem to make ports conflict with themselves, but this is
actually not the case due to the check-*-conflicts logic implemented
in bsd.port.mk, which excludes self-conflicts.

PHP based ports have been ignored in this commit as requested by the
committers currently working on the php-8.1 import.

*/*: Remove redundant '-[0-9]*' from CONFLICTS

The conflict checks compare the patterns first against the package
names without version (as reported by "pkg query "%n"), then - if
there was no match - agsinst the full package names including the
version (as reported by "pkg query "%n-%v").

Many CONFLICTS definitions used patterns like "bash-[0-9]*" to filter
for the bash package in any version. But that pattern is functionally
identical with just "bash".

Remove # $FreeBSD$ from Makefiles.

First pass at moving manpages to share/man for category a*

archivers/par: Mark jobs unsafe

Under multiple jobs, This port showed par.c trying to use header.h before
it's target completely built the header, and thus failed.

Support stage

Add NO_STAGE all over the place in preparation for the staging support (cat:
archivers)

Adjust PKGNAME, register CONFLICTS against `textproc/par'.

Enforce correct type (per specification) and drop unneeded backslashes.

Add par 0.03.01, an archiver for Quake I and II packed data files (pakX.pak).
It supports listing, extraction, and creation of .pak archives.
