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
error message.
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.

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

This change adds the method getMathTableName that will
allow renderers to access their specific table in the
database.

* Removes the MathJax heuristics that decides
if equations are centered or left-aligned.
* Introduces the attribute display to specify
if the math element is rendered in inline,
display, or inline-displaystyle.
* add css rules for display / inline math images

* 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.

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.

This patch adds wfDebugLog() calls for conditions related to texvc invocations.
The logs are grouped under a 'texvc' group, added for this purpose. The reason
for logging into a separate channel is that the Math channel is too verbose for
production use on the Wikimedia cluster.

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.

Moves writeCache call back to hooks (changed in 9ba4ef269d)
and makes it unconditional, so only one part of the code decides
whether to write to the cache.

Change I9b1d68c4faa8d177d8d0088fa1a5879caed4f1fe added an indiscriminant call
to writeCache(). I assume that it was supposed to be regulated by the check for
$this->isRecall() (which is a getter for '$this->recall'), but there was no
concomitant change to ensure that recall is set true on cache hits.
My fix does not set recall to true. The style of "pass-by-attribute" is tricky
and should be factored out by a subsequent change. This change moves the call
to writeCache() so that it is only called on cache miss.

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.
