We use the checked version of the TeX string and
not the original user input string to ensure that
the layout is the same and no mediawiki specific
macros such as \reals is needed to render the alt
text with a regular LaTeX installation.

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.

* 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.

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).

* 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.

Chrome in particular would end up with fairly small and inconsistent
background sizes when using background-size: contain;. This makes sense
according to the docs at
https://developer.mozilla.org/en-US/docs/Web/CSS/background-size, which
doesn't specify that the background actually has to fill the entire element.
background-size: 100% 100%; does force full-size scaling, which is what we
want. Verified to work as expected in Chrome 38 on Linux.

HTML tidy will strip empty spans, so don't use one for the fallback image. We
use a meta element instead, as that does not normally render at all & doesn't
have any default styling coming with it.

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
