Attempt to produce a DEP-5 machine-readable debian/copyright

I've treated section 55 of CDPA as though it's a licence, which it
kind of is.  I assume that quoting a single section of legislation
doesn't then require me to provide a copy of the Open Government
Licence as well.

Debian Policy section 2.3 says that a copyright file needs to contain
copyright statements only if the licence requires such statements.
CC0 does not, and so I've left them out.  Since the "Copyright" field
is mandatory, I've provided it but left it empty (with an explanatory
comment).

-This package was Debianised by Ben Harris <bjh21@bjh21.me.uk> in 2024.

-The upstream sources for Bedstead were obtained from

-This explanation of Bedstead's copyright situation comes from

-
-/*
- * Many of the character bitmaps below formed the typeface embodied in
- * the SAA5050 series of character-generator chips originally made and
- * sold by British company Mullard in the early 1980s.  Copyright in the
- * typeface will still be owned by Mullard's corporate successors, but
- * under section 55 of the Copyright Designs and Patents Act 1988 that
- * copyright is no longer infringed by the production or use of
- * articles specifically designed or adapted for producing material in
- * that typeface.
- *
- * The rest of the glyphs, and all of the code in this file, were
- * written by Ben Harris <bjh21@bjh21.me.uk>, Simon Tatham
- * <anakin@pobox.com>, and Marnanel Thurman <marnanel@thurman.org.uk>
- * between 2009 and 2024.
- *
- * To the extent possible under law, Ben Harris, Simon Tatham, and
- * Marnanel Thurman have dedicated all copyright and related and
- * neighboring rights to this software and the embodied typeface to
- * the public domain worldwide.  This software and typeface are
- * distributed without any warranty.
- *
- * You should have received a copy of the CC0 Public Domain Dedication
- * along with this software. If not, see
- * <http://creativecommons.org/publicdomain/zero/1.0/>.
