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.

Turns out that with the upgrade to 2.1 this is now included in core
MathJax, so we don't need the extension anymore.

This command was not yet supported. This implements it as a noop.
In MathJax it's not really useful to be able to define the background
color as sometimes is required in rendered png mode.

This gracefully handles: <span class="tex"><span class="tex"

inside element attributes.

With the new renderTex hook of https://gerrit.wikimedia.org/r/61183
there is no need for hardcoded support for these 2 scripts. The
scripts in question should call the hook themselves.

We move the block/inline styling (aka display vs textstyle) markup into
a filter used just before rendering. This way the 'used' formula will
not suddenly contain styling information that wasn't part of the
original formula.

* $inputhash is also never used.
* Additional comments.

This code is never used and will not be used in the future.
Adressing the equation for search will be handled by the
MathSearch extension. There will be a hook function to label
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.

SQLite has global indices, not per table one. When using the database
updater to create the `unitest_math` table, we would get an error
with a duplicate `math_inputhash` index which is created by the the
database installer.
This patch skips the testBasicCreateTable() test on sqlite.
Change-Id: I6da56d67d7af45f86cf6163cf73f5464505b43f3
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).

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.

Physikerwelt asked for some guidance on how to write good unit tests for
classes that depend on external resources. I wrote a few to serve as examples
for additional tests. Because they have an ulterior didactic purpose, the
comments are a bit more verbose than I would otherwise like, but despite that
the tests are good enough to merit being merged.

This change adds test cases for the MathSource class and registers a
