* $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.

Make LaTeXML setting configurable with the new global
variable $wgDefaultLaTeXMLSetting.
PS: This variable can be specified as an array or a
string. If specified as an array, the
array('a'=>'b','c'=>array('e','f'))
would be transformed to the equivalent setting
a=b&c=e&c=f
,which is the input format for the LaTeXML daemon.

- Remove MathMathJax.php, which uses exactly the same output as MathSource.php.
- Make wiki2jax able to handle texvc output as a preview before MathJax rendering.

This change adds test cases for the MathSource class and registers a
hook for loading these tests. Also adds documentation about how to run
these tests in README.

The Math.body file which contains the MathRender class was split in the following way:
- Math.base contains the base class with the database related stuff and provides an abstract interface
- Math.source and Math.MathJax handle the plain tex string output. There are two classes since they
will differntiate in the future I think.
- Math.texvc contains the "old" implementation of png generation with all the file handling related stuff
- Other implementation of math renderer can be added in the same style.
- Cleanup to better follow coding conventions.
- Changed LockManager to 'fsLockManager'
The first attempt restructure the class layout and introduce LaTeXML at the same
time was dropped. Instead this was split up into two phases.
This commit only deals about the restructuring of the math module design.

* drop some of the init lines that don't appear to work/be needed
* only load MathJax.js through ResourceLoader; let MathJax's loader handle the rest
This gets us working in Chrome, where previously we hadn't initialized correctly. Should also help in IE, still needs testing.
Will probably want to swap in the pre-minimized versions of the files at some point, but the expanded ones are fine at this stage of work.
* Pulled in MathJax 1.1 (minus the 112 megabytes of PNG "fonts")
* Pulled in some of <https://en.wikipedia.org/wiki/User:Nageh/mathJax> bits for initialization
This doesn't currently override PNG images, but does replace the text-form if you configure it.
If enabled, by default loads MathJax from a CDN and forces all equations through MathJax when JavaScript is available -- the image or source form gets used only as <noscript> fallback.
This has a couple of problems for us:
* if scripts are missing -- such as when viewed via MobileFrontend -- you end up with no math at all, as the <script type="math/tex"> bits get ignored but the <noscript> still hides the images.
* while MathJax is loading things, blank spots on the page may appear and stuff jumps around
* if loading new text in via ajax, it doesn't trigger there
Also using some fairly default config, no idea how appropriate it is. Hoping to get some insight from Nageh who's done some of the MathJax work on Wikipedia so far - <https://en.wikipedia.org/wiki/User_talk:Nageh#MathJax_integration_into_stock_MediaWiki>
MathML mode was so incomplete most people thought it simply didn't work (bug 25646).
HTML modes often rendered poorly (eg req bug 24207 to set default to PNG on some sites)
This may cause regressions in that simple "equations" of just variables that came out as HTML
will now render as PNGs that don't get aligned properly with the text baseline. Fixing this is
covered by bug 32694: <https://bugzilla.wikimedia.org/show_bug.cgi?id=32694> to retrieve the
baseline info from dvipng and position images to fit.
Note that because of the way user options are pulled in to the oarser cache key, some folks
may see cached pages with their old settings until they get redone or they save their prefs
again and have it normalized.
The 'math' table will no longer be created on a default install unless you've explicitly enabled the Math plugin at install time; the usual update.php procedure will add it in.
Postgres, Oracle, MSSQL, and DB2 variants are included -- broken out from the core files -- but have not been tested.
I know there has been some code duplication in parser test infrastructure but could only find one instance of the parser test temporary table setup to remove the 'math' table from (the extension adds it back via the hook). If the phpunit-based runner breaks, please track it down and fix it there too.
* MW_MATH_* constants are now defined in Math extension
* Language::getMathNames() is removed
* mathNames section in message files is removed
* A hardcoded preference override in refreshLinks moved to MaintenanceRefreshLinksInit hook
*coding style tweaks
*documentation
*check for MediaWiki environment in the main setup file
*add extension credits
*add i18n file (only English at the moment); messages from core MessagesEn.php
This is a follow-up to Brion's r85706.
* (bug 14202) $wgUseTeX has been superseded by the Math extension. To re-enable
math conversion after upgrading, obtain the Math extension from SVN or from
http://www.mediawiki.org/wiki/Extension:Math and add to LocalSettings.php:
require_once "$IP/extensions/Math/Math.php";
This is an initial stab, and a few things remain to be cleaned up:
* messages need to be moved from core to extension
* MW_MATH_* constants should be moved to the extension from core
* old back-compat math names interfaces using those constants should be removed from message files
* classic edit toolbar's math button should be added from the extension (or else dropped) -- currently there's not a clean hook, but could do it by JS
* couple of things like the 'armourMath' function on Language & LanguageConverter may want to be redone just as an unconditional, if that's simpler.
Setting $wgUseTeX alone will no longer have any affect. The var's still there for the moment as a few bits still need to be fully moved out from core.
