dubious copyright notices in emacs.tiff, allegro.lua, etc.

[Paul Eggert]

I did a quick pass through the emacs-26 source files and found the 
following files with dubious copyright notices. We should fix this one 
way or another.

The following image file is used in the GNUstep port:

* nextstep/GNUstep/Emacs.base/Resources/emacs.tiff says 'Copyright (c) 
1998 Hewlett-Packard Company' with no permissions notice. Is this 
because that TIFF file was created by a tool that inserts that copyright 
notice into the image file for some reason? If so, what's the reason? 
Can we use a different tool to create a TIFF-format image that doesn't 
have this copyright issue? I'll CC: Adrian Robert about this, as he 
added that file on 2008-07-15.

The following files were added by Eli on 2015-05-12, as part of a test 
suite for etags. As these are just for testing Emacs, presumably it 
shouldn't be much trouble to remove them if there are real copyright 
issues here:

* test/manual/etags/lua-src/allegro.lua says '-- Copyright (C) 2001-2004 
by David A. Capello' and 'Read "LEGAL.txt" for more information.' but 
there is no LEGAL.txt.

* test/manual/etags/prol-src/natded.prolog says 'Copyright 1995, Bob 
Carpenter' with no permissions notice.

* test/manual/etags/prol-src/ordsets.prolog says 'Copyright(C) 1988, 
Swedish Institute of Computer Science' with no permissions otice.

* test/manual/etags/ps-src/rfc1245.ps says 'Copyright (c) 1986,87,89 by 
Frame Technology, Inc.  All rights reserved.' with no permissions notice.

I've updated this file to the Emacs 25 icon, and the above issue no
longer applies.

It shouldn't be much trouble, provided we can find alternative test
files for the same languages.

FWIW, I don't think there are any real copyright issues here, I looked
at all these files at the time and removed those which had copyright
problems.

I'm afraid that's too much trouble for me to handle. I don't know what the tests 
are for and would rather not get entangled into them if there happen to be real 
copyright issues with them.

Most likely so. Still, it would be nice if Emacs set a good example with respect 
to copyright.
