Landon Curt Noll 2b92c89be8 fix and improve links within the web site 
Entry source is now prog.c for IOCCC years 2014 thru 2020,
or is now dirname.c IOCCC years 1984 thru 2013.

To achieve this state, we renamed the following:

renamed:    2004/hibachi/src/hibachi.c -> 2004/hibachi/hibachi.c
renamed:    2012/omoikane/nyaruko.alt.c -> 2012/omoikane/omoikane.alt.c
renamed:    2012/omoikane/nyaruko.alt2.c -> 2012/omoikane/omoikane.alt2.c
renamed:    2012/omoikane/nyaruko.c -> 2012/omoikane/omoikane.c
renamed:    2012/omoikane/nyaruko.orig.c -> 2012/omoikane/omoikane.orig.c

Modified `bin/subst.entry-index.sh` to add to entry `index.html` file,
links to the `Makefile` and the _C code_ to the top navigation bar.
Changed `bin/subst.entry-index.sh` VERSION from "1.2.2 2024-02-25"
to "1.3 2024-03-02".

Moved printing the Inventory link in the top navigation bar
from `bin/subst.entry-navbar.awk` to `bin/subst.entry-index.sh`.
Changed `bin/subst.entry-navbar.awk` VERSION from "1.0.1 2024-02-23"
to "1.1 2024-03-02".

Moved printing the Inventory link in the top navigation bar
from `bin/subst.year-navbar.awk` to `bin/subst.year-index.sh`.
Changed `bin/subst.year-index.sh` VERSION from "1.0 2024-02-11"
to "1.1 2024-03-02".
Changed `bin/subst.year-navbar.awk` VERSION from "1.0 2024-02-11"
to "1.1 2024-03-02".

Added location names (both default and common) to `author.html`.
Changed `tmp/gen_author_json.sh` VERSION from "1.0 2023-06-06"
to "1.1 2024-03-04".

Added location names (both default and common) to `author.html`.
Changed `bin/gen-authors.sh` VERSION from "1.2 2024-03-09"
to "1.3 2024-03-04".

The manifest and the resulting `.entry.json` files have been changed
for `2004/hibachi` and `2012/omoikane`.

The Makefiles for  `2004/hibachi` and `2012/omoikane` copy the
source file into the "previously used location".  The `make clobber`
rule removes the copied source.  The `.gitignore` files have been
updated accordingly.

Improved how the concept of IOCCC terms _entry_, _author_ and _submission_ are
used in markdown files.

Links to markdown files (files ending in .md) within the repo were
changed to link to HTML files (files ending in .html).  Special cases
where `README.md` became `index.html` were modified accordingly.

Fixed URL for `bugs.html` in Makefile comments.

Fixed name of `bin/sgi.sh` referenced in comments in `.gitignore` files.

Links to locations within the repo are now relative.  For example a
link to `/contact.html` may become `../contact.html' or '../../contact.html`
depending on the directory level of the markdown file.

Nearly all links with absolute URLs under _https://www.ioccc.org_
or `https://ioccc-src.github.io/temp-test-ioccc_ have been changed to
relative paths within the repo.  Some exceptions to this (such as
referring to a GitHub repo) were preserved.

Fixed a number of inside `faq.md` and `bugs.md`.

Added HTML name tags (in the form of an _entry_id_) for each entry
referenced in `bugs.md`.  Fixed links from outside of `bugs.html`
into `bugs.html` accordingly.

Where FAQ entries are referenced, a named tag is used so that if a
FAQ is ever renumbered, links outside of `faq.html` will still work.

Changed the _inventory_order_ of a compressed tarball from _300_
to _100000_.  While this may have been done for the manifest,
this changed had not yet been propagated into the `.entry.json` files.

Links to web sites that were in the for <URL> are now [URL](URL).

Performed `name www` to process all of the above.

Improved format of `authors.html`.  Full names are now bold.
Location codes are now links back into `location.html` and
location names (both default and common) are now italics.
Added _author_handle_ each author.

Changed `bin/gen-authors.sh` VERSION from "1.1 2024-02-25"
to "1.2 2024-03-09".

Improved format of `location.html` as location codes are now bold,
author counts in a given location are now bold, and location names
(both default and common) are now italics.

Changed `bin/gen-location.sh` VERSION from "1.0.1 2024-02-23"
to "1.1 2024-03-04".

Added italic location name after location code in entry
`index.html` files.

Changed `bin/output-index-author.sh` VERSION from "1.4.1 2024-02-23"
to "1.5 2024-03-04".

Added _Location of authors_ to the sidebar as a link to `location.html`.

TODO: While nearly all of the above mentioned changes are likely correct,
      they likely introduced a few errors that need correcting.

<h2 id="judges-remarks">Judges’ remarks:</h2>
<p>Do get lost in the program’s line of thought! :-)</p>
<h2 id="authors-remarks">Author’s remarks:</h2>
<h3 id="whats-this">What’s this?</h3>
<p>What do you see? On the left, you will see an enumeration of all
successive <a
href="https://en.wikipedia.org/wiki/Prime_number">primes</a> from 2 to
the parameter you gave to the program. On the right part, you can see
the sieve used to find these primes. The big diagonals from right to
left are used to erase composed numbers. When no diagonal crosses a
number, then the left cell take value 1 and the number is prime.</p>
<p>The parallel version of this algorithm works in real time
<code>n</code>. This C sequential version is slower as it works in
<code>O(n*log n)</code>. But you have some nice picture instead… the
cost is a constant number of operation for each character printed on the
screen.</p>
<h3 id="why-did-i-write-this">Why did I write this ?</h3>
<p>Let’s just quote the <a href="../../faq.html">FAQ</a>:</p>
<p>Q: Are there types of entries that are submitted so frequently that
the judges get tired of them?</p>
<p>A: Yes, there are types of entries that show up over and over again.
The guidelines say:</p>
<pre><code>We tend to dislike programs that:
are similar to previous winning entries
We like variety. However too often we see (please look at the winning
examples given to be aware of the level of the competition):
(snip)
generating small primes (below is the list of all prime related entries)
1985/august
1988/applin
1994/weisberg
1995/makarios
1996/dalbec
2000/bellard
As you can see, just a list of primes (let alone small primes)
does not cut it anymore.
(snip)
entries that use some complex state machine/table to print something
1988/isaak
1988/phillipps
Unbeaten for 12 years and counting...</code></pre>
<p>I think this is enough motivation for trying to submit a program
which uses some complex state machine/table to generate small primes and
print them.</p>
<h3 id="the-way-it-works">The way it works</h3>
<p>This program simply prints the space-time diagram of some particular
cellular automaton. The automaton is a 9-state automaton by <a
href="https://sk-m-wikipedia-org.translate.goog/wiki/Ivan_Korec?_x_tr_sl=auto&amp;_x_tr_tl=en&amp;_x_tr_hl=en-US&amp;_x_tr_pto=wapp">Ivan
Korec</a> in 1998. It is an optimization of an old automaton for
recognizing primes designed by <a
href="http://richardallenfischer.com">Fischer</a> in 1965.</p>
<p>The table of the automaton is encoded into the string <code>e</code>
and consists of 345 transitions of the kind
<code>ff(left,middle,right)</code>. This encoding into <code>e</code> is
obfuscated to reduce its size, restrict it to characters 32 to 127 and
guarantee a constant time.</p>
<p>The main loop simply iterates this transition function on each
cell.</p>
