The signature of the Hook function is not respected.
Thus parameters need to be passed by reference explicitly.
For syntax validation to pass, this requires
mediawiki-codesniffer to 0.6.0

Most info-level log entries are actually debug messages, which should
not end up in the production log by default, so adjust them.
Only the Mathoid-powered TeX check fail has been promoted to info so
that we can quickly identify such requests from pages.

* Do not contact RESTbase in texvc rendering mode and
use the well established tex checking that is already build
into texvc.
* Do not use RESTbase in LaTeXML mode.
Background:
In I1982612e8c6a356e3dbdf447724ac82e5968cc77 RESTbased replaced
texvccheck that was a derivate of texvc designed for people
that wanted to use secure MathML rendering using mathoid.
The integration of mathoid to restbase made this feature obsolete.
However, texvccheck was not only used to check the latex input
that was sent to mathoid, but also the string which was sent to texvc.
Since texvc has already build in tex checking this is not
required and does not improve security.
Finally, users updating from old versions of the math extension
(prior to 2014) that do not have textexvccheck installed,
do not need to compile the texvccheck binary after this change.
PS5: Also treats the case where VisualEditor is not installed.

The workaround to save PNG images calls the hook wrong,

- Merge fallback-svg and fallback-png into one fallback-image class.
- Move the vertical centering of PNG to MathTexvc and ext.math.js.
- Remove "img" from ext.math.css to reduce CSS specificity and make
style easier to override by user stylesheets.
- Add a comment about the !important rules for centering in
display mode.
- Only load ext.math.scripts in MathML mode.

Use the cached function isInDatabase rather than readFromDatabase to
avoid unnecessary read operations on the database.
Currently, readFromDatabase is usually called only once during instance
livetime. But after I455b41c8b8d918f4c34f6c115194d227a8394e0a has bben
merged chances are that it's called twice.

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.

This change adds a mechanism that allows

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.

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.

Moves writeCache call back to hooks (changed in 9ba4ef269d)

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.
