[upstream changes]
Release 2.3.1:
By John A. Magliacane <kd2bd@amsat.org> (05-Aug-2023):

* Fixed a bug that caused the "Upcoming Passes" list in Multi-Satellite
  tracking mode to occasionally produce erroneous results if one or
  more satellites in the database had decayed from orbit.

* The Vocalizer feature was modified to prevent it from being executed
  by a user keyboard command until after the current speech announcement
  has terminated.

* The earthtrack compilation script was modified to prevent the
  "undefined reference" errors some users experienced during the
  linking phase of the compilation process.

* All references to www.celestrak.com in the "kepupdate" script have
  been changed to celestrak.org due to the site's name change.

* Several other small coding changes were made.

[db changes]

- Upstream does not come with a proper build infrastructure hence
  build is done in our port Makefile now instead of copied Makefile.
- portlint and portfmt ran clearly as did poudriere.
- Added earthtrack, kepupdate and moontracker binaries
  but did not add gsat which should be a separate port IMO

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)

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.

This commit implements such a proposal and moves one of the WWW: entries
of each pkg-descr file into the respective port's Makefile. A heuristic
attempts to identify the most relevant URL in case there is more than
one WWW: entry in some pkg-descr file. URLs that are not moved into the
Makefile are prefixed with "See also:" instead of "WWW:" in the pkg-descr
files in order to preserve them.

There are 1256 ports that had no WWW: entries in pkg-descr files. These
ports will not be touched in this commit.

The portlint port has been adjusted to expect a WWW entry in each port
Makefile, and to flag any remaining "WWW:" lines in pkg-descr files as
deprecated.

Update the CONFLICTS definitions of ports in the following categories:

- accessibility
- archivers
- audio
- benchmarks
- biology
- cad
- chinese
- comms
- converters

An attempt has been made to use generic conflicts patterns that do not
have to be updated whenever a new version of a conflicting port is
added to the ports system.

There is a misunderstanding that the port being built/installed has to
be omitted from the conflicts pattern. This is not true - the port
being built is implicitly non-conflicting due to logic in bsd.port.mk.

While here, avoid useless call on sed where easily possible

While here, minor whitespace fix
