* Otherwise all future <math> hits will check the wrong file
(which may not exist), recreate the png, and store over the
proper file (even if it was already there). Update the DB to
point to the right hash instead.

Introduce different error messages for missing texvccheck and
texvc and update the README file.

Mathoid is supposed to be run at a server separated from
the MediaWiki math extension. It should use the MathJax
version customized to the MediaWiki needs as submodule.
It has been moved to the new repository
mediawiki/services/mathoid

The output of texvccheck is not only "checked" but also
rewritten to another form.
(For example $\R$ is transformed to $\mathbb{R}$.)
But the output might not be a valid input for the thexvccheck
part of texvc, like it happened in for the example given in the bug
description.

* $wg(.*) variables from extension should start with the extension name
i.e. for extension Math $wgMath(.*)
* But keep $wgUseMathJax, because it has been used for 2 years now.
* Add release notes

Since math has been moved from core to an extension
it should take care of the caching by its own.
Therefore, a call to the parserOptions::getMath is removed
and own caching logic is introduced, once getMath is removed
from core.

$wgUseTeX is not needed in the extension. For backwards compatibility,
it's also set in /mediawiki/includes/DefaultSettings.php and used in
/mediawiki/includes/EditPage.php only.

The user input specified in the math tag a. la
<math>E=m <script>alert('attacked')</script>^2 </math>
is verified in PNG rendering mode, but not in plaintext, MathJax
or LaTeXML rendering mode. This is a potential security issue.
Furthermore, the texvc specific commands such as $\reals$
that is expanded to $\mathbb{R}$ might be rendered differently
depended on the rendering mode.
Therefore, the security checking and rewriting portion of texvc
have been extracted from the texvc source
(see I1650e6ec2ccefff6335fbc36bbe8ca8f59db0faa) and are
now available as a separate executable (texvccheck).
This commit will now enable this enhancement in security and
provide even more compatibility among the different rendering
modes.

Many things in MediaWiki (and various on-wiki templates, at least on
enwiki) output error messages wrapped in <strong class="error">. MathJax
parsing all of these (added in I1199cb34) is completely broken.
What appears to have been intended is that MathJax would parse the
errors output by MathRenderer.php. So let's add a "texerror" class to
those and have MathJax look for that class instead.

texvc had several tasks in the past:
1 checking the input
2 convert MediaWiki custom syntax to standard LaTeX
3 run LaTeX
4 convert dvi2png
This change provides a simplified version that performs
only steps 1+2. This is required to avoid security problems
with tools like MathJax, especially if these tools are
run at the server-side.
