This change allows to registered users
to test the new MathML rendering mode.
Invalid settings for math rendering mode
will default to MathMathML.

* id: Allows to name equations
and deep link to equations
* forcemathmode: Allows to override the user defined rendering mode.
This feature is useful for help pages and discussions about rendering.

required for MediaWiki instances that want to
incorporate MathML sources like for instance pubmed

Adds a new constructor that allows
to create a new instance of the MathRenderer
based on an inputhash.
This method is required for the Specialpage
and the MathSearch extension.

Currently the method render always returns
a html string that can be a string that
represents the correct result or a rendered
error message.
This change splits rendering and
fetching of the HTML output.
This simplifies the logic of the rendering
and caching mechanism.
Now the render method returns a boolean that
indicates if the rendering was sucessful or
not.
Step 2/2
Warning: Errors in this change might affect
caching logic and squid caches.

Currently the method render always returns
a html string that can be a string that
represents the correct result or a rendered

This change adds a mechanism that allows
to fetch the HTML output.
In a followup commit the rendering function
is changed to return a boolean value rather
than the rendering result.
This will simplify the error handling and caching.

Currently the PNG and the LaTeXML rendering mode
use a common table in the database. If both rendering
modes are allowed in a wiki simultaneously this causes
problems, because the fields are continuously overwritten.
This is patch changes the logic of the rendering
engine to use the specific database.
The caching logic is now simpler to understand.
A entry is written to the database if the changed field
of the MathRenderer class is true. Is is triggered by the
setters of the database relevant fields.

To adjust the selectable math rendering modes in user preferences $wgMathValidModes
is introduced.
* $wgUseLaTeXML becomes unnecessary use $wgMathValidModes[] = MW_MATH_LATEXML;
to enable the LaTeXML rendering mode
* add $wgMathValidModes[] = MW_MATH_MATHJAX; to enable MathJax
Currently, MathJax is bound to the MW_MATH_SOURCE rendering mode.
This change makes the base mode user configurable.
That means before MathJax is loaded the png fallback image could
be displayed.
ATTENTION: This change modifies global variables as follows:
* MW_MATH_MATHJAX is deprecated.

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.

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.

- 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.

Adds a new method isChanged() for determining if a value was changed.
This is done in preparation for a more elaborated caching method that is
handled inside the abstract base class.

the equations.

A wfDebugLog() was attempting to concatenate a string with a Blob object
which does not support conversion to a string. Since that was used to
show some hash, display the current string hash instead.
Furthermore the input-hash, which can be calculated from the TeX input
string was displayed, which is not very helpful. The variable hash is
calculated by texvc and can be used to search for the rendered image in
the filesystem.

adds two new phpUnitTests for the abstract MathRender class
and another one that test the basic database access.
Therefore the read and write methods have been made changed
from protected to public.

Output hash calcuation sometimes fails because of Texvc failure for
example, and $this->hash remains ''. At this time inserting null as
outputhash into database is improper, because that column is NOT NULL.
With this patch an empty string '' is inserted instead, and the if-check
is modified to avoid cases where ->hash exists but evaluates as null
(for example when it's '0000000000...' though it's extremely rare).

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.
