Previously, the 'action=purge' parameter could not be
accessed by the math extension, since 'action=purge' caused a reload
of the page, even before the math extension was called. However,
before MediaWiki 1.29.+ additional GET request parameter were
forwarded to the next page and could be evaluated by the math
extension. Thus, an additional parameter 'mathpurge=true' was added
to re-render formulae. However, it seems that this additional GET
parameter is no longer being forwarded.
This change reads the refer header to check if 'action=purge' was
passed. This makes the mathpurge parameter obsolete.

When the user specifies the mathpurge=true query parameter, the Math
extension needs to prompt RESTBase to regenerate the renders for all
formulae on the page and consequently issue Varnish purge requests. This
behaviour is achieved by including the `Cache-Control: no-cache` header
when requesting a render. Since RESTBase regenerates all of the renders
when it receives the header, send it only for the first content request;
if subsequent content requests are made, RESTBase will already have the
new renders.

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.

* This will increase the performance of tex rendering for all
rendering modes since no shell access is required anymore.
Merge with caution. If the connection to restbase fails, rendering
of new formulae will be completely disabled i.e. broken.
Change-Id: I1982612e8c6a356e3dbdf447724ac82e5968cc77
Tex validation should be skipped if checking is disabled.
Consequently if 'disable tex filter' is set to 'never' it's a double
negation and tex should always be checked.
If 'disable tex filter' is set to always, never check tex.

Redo Ibf6bdbd4ea36b4905445d5878f32f7e0b2bc8bac, which was
reverted by I029328849f05ec2afcabf38d2b79b337cb54cbd5.
In addition this patch simplifies the tex sent to the mathoid
server. Instead of {\displaystyle {\textstyle ... } } only
{\textstyle is sent (which overwrites \displaystyle anyway).

In I6d1094ece79e912d9ddbef6681a25196c7a6e801 math styles
were renamed from integer constants to string constants.
Before NULL corresponded to inlineDisplaystyle. This is
no longer the case so NULL has to be replaced by the actual
default value.

* MathDebug was intended to provide advanced debugging functionality
for the math extension. However, the interesting debugging and
logging feature never made it from the debug branch to the master.
* The current debug functionality is mostly useless. Only some values
are written to memory and never used thereafter.
* This change moves the existing functionality to the MathSearch
extension and introduced the required hook for that.
Details:
* $wgMathDebug is removed
* A new Hook MathRenderingResultRetrieved is created
* The math rendering object is printed to the svg error
page if wgDebugComments is active (instead of wgMathDebug)

MathMathML::renderingRequired called the getSvg
function in MathLaTeXML that caused an automatic
rerendering of the SVG image if it was not cached.
That this rendering is triggered from the function
renderingRequired is contra intutive and should be
avoided.

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.

In a followup commit the rendering function

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.
