Landon Curt Noll f29b37e49a improve HTML menus, add social.html, prep for IOCCC28 winners
Prepare for the winners of **IOCCC28**.

> However these are not the 2024 droids you are looking for.  :-)

The HTML menu (both JavaScript and non-JavaScript) has been updated.

The `Status -> Rules and guidelines' have been replaced with two
separate menus `Status -> IOCCC rules` and `Status -> IOCCC guidelines`.

Added a new top level `social.html` page: built from a new `social.md`.

Sorted rules for building specific web pages in the top level `Makefile`.
Added `make social` to make the `social.html` page from `social.md`.

The `bin/gen-top-html.sh` now is able to process a argument of **social**
to process the new top level `social.html` page.

Changed `bin/gen-top-html.sh` VERSION from "2.0.0 2025-03-13"
to "2.0.1 2025-07-25".

Below `About -> Home page` a new `About -> IOCCC social media` menu item
as added.

Because the menu change touched every HTML file, we changed the general
copyright date range for HTML files from "1984-2024" to "1984-2025"
due to the extensive changes made for **IOCCC28**.

Those markdown files that were modified in 2025 had their copyright date
range also changed from "1984-2024" to "1984-2025".

Rebuilt tarballs and sitemap due to the extensive HTML rebuilding.

Ran `make update` to perform the above.

<h2 id="to-build">To build:</h2>
<pre><code> make</code></pre>
<p><strong>NOTE</strong>: We FORCE the use of <code>-O0</code> even if someone overrides it because this entry
will not work with it enabled.</p>
<h2 id="to-use">To use:</h2>
<pre><code> ./burley</code></pre>
<p><strong>NOTE</strong>: you need to input a number first. See judges’ remarks below for
information on how to play.</p>
<h2 id="judges-remarks">Judges’ remarks:</h2>
<p>This is a <a href="https://en.wikipedia.org/wiki/Draw_poker">draw poker</a> program. You
start with $100. Input alternates between your bet and which cards to keep.</p>
<h3 id="example">Example:</h3>
<p>Here is an example.</p>
<p>First, enter your bet (say <code>5</code>) (for $5, defaults to $1). You might then see
something like:</p>
<blockquote>
<p>J Q J 9 5<br>
C H D S C</p>
</blockquote>
<p>That indicates your hand is Jack of Clubs, Queen of Hearts, Jack of Diamonds, 9
of Spades and 5 of Clubs.</p>
<p>Now enter what cards you want to keep (enter 0 to 5 digits between 1 and 5).
Let’s say you want to keep 1, 2 and 3 so you enter <code>123</code>. You should see
something like the following after you hit enter:</p>
<blockquote>
<p>J Q J J Q<br>
C H D S C</p>
</blockquote>
<p>which tells you that your new hand is Jack of Clubs, Queen of Hearts, Jack of
Diamonds, Jack of Spaces and Queen of clubs. You might now see something like:</p>
<blockquote>
<p>$145 (45)</p>
</blockquote>
<p>which tells you that your new balance is now $145. You had a Full House so your
payoff is 9 times your bet == 45.</p>
<h4 id="payout">Payout:</h4>
<p>The payout is according to “Vegas rules”:</p>
<ul>
<li><strong>Straight Flush</strong>
<ul>
<li>50 times your bet</li>
</ul></li>
<li><strong>Four of a Kind</strong>
<ul>
<li>25 times your bet</li>
</ul></li>
<li><strong>Full House</strong>
<ul>
<li>9 times your bet</li>
</ul></li>
<li><strong>Flush</strong>
<ul>
<li>6 times your bet</li>
</ul></li>
<li><strong>Straight</strong>
<ul>
<li>4 times your bet</li>
</ul></li>
<li><strong>3 of a Kind</strong>
<ul>
<li>3 times your bet)</li>
</ul></li>
<li><strong>2 Pair</strong>
<ul>
<li>2 times your bet</li>
</ul></li>
<li><strong>Jacks or Better</strong>
<ul>
<li>1 times your bet</li>
</ul></li>
</ul>
<h3 id="other-things">Other things:</h3>
<p>The program allows you to go into debt. However I’m sure you would never
control-C to kill the program just because you got behind, right? On the other
hand the program never willingly exits, so you have to leave even when you are
ahead. :-)</p>
<p>Can you figure out a winning betting “strategy”? Then can you modify
the program so this “strategy” no longer works?</p>
<p>Notice the clever use of <code>setjmp(3)</code> and <code>longjmp(3)</code> calls. Can you keep track
of what state is being saved and restored?</p>
<p><strong>NOTE</strong>: the author talks about how it is a single statement. This might not be
strictly true in 2023 with the fixes for it to work so you can look at the
original file <a href="https://github.com/ioccc-src/winner/blob/master/2004/burley/burley.orig.c">burley.orig.c</a> to see
what is meant.</p>
<h2 id="authors-remarks">Author’s remarks:</h2>
<p>This program plays draw poker. What is unusual about it is that it
is written as a single statement – count the semicolons! (OK, there
are really three statements if you count the variable declarations.) To
keep things simple, I have avoided the C preprocessor and tricky
statements such as <code>if</code>, <code>for</code>, <code>do</code>, <code>while</code>, <code>switch</code>, and <code>goto</code>.</p>
