It's observed that some vandals use {{subst:void}} to trick the system
and other users and this new variable may help.
It would be nice to be possible to diff this variable against
old_wikitext, but it needs some performance consideration.

lot of code was using ::merge() to create a new AbuseFilterVariableHolder
this is now simplified using a single addHolders method.
merge() still exists as its usful as a static function.
addHolder() is deprecated.

AF is setting several lazy load variables for the currently editing user.
To do this it's passing along the user name extracted from a user object
and generating a new user object later from that name which is of course
pointless. With this patch I'll pass user objects directly to prevent that.
On top of that I've deprecated a method in AFComputedVariable::compute which
was redundant as there is a more generic one which can solve that task
just fine.
Furthermore I've changed the logging behaviour from serializing the whole
AbuseFilterVariableHolder object to only store the variables. That has two
major advantages:
* The amount of data that needs to be saved on a filter hit is reduced
to about 1/10 of what the old version needed.
* This is much more forward compatible as the old way of saving this
relied on the class structure to stay the same while this is a simple
array containing the vars.
On top of that we now only log variables already set by the time
a filter is hit. On top of the obvious performance increasement
that makes it easier for the user to spot the relevant data.
Another thing this change alters is the way the AbuseFilter internally
works with AbuseFilterVariableHolder objects. Right now we use one for
testing the filter(s) and later we use another one to compute the same
data again in case a filter was hit (for logging)!
This is not thoroughly tested yet, but way more sane than what we're
currently doing!

AFComputedVariable::compute() caused fatal errors when trying to handle
non-text content, e.g. in Special:AbuseLog.
For now, we just stub out some variables for non-textual content. Extensions
can still provide values for these using the AbuseFilter-interceptVariable hook.
A real solution requires us to make the Content object available along with the
variable array, or at the very least log the base revision id of filtered changes.

This makes AbuseFilter use EditFilterMergedContent if support for
the ContentHandler infrastructure is present. This means living
without some nice bits of context, because EditFilterMergedContent
doesn't provide an EditPage object.
This requires core change I99a19c93 to work correctly.

This patch allows the current AbuseFilter to work with 1.19, by only
using MWTimestamp if MediaWiki is version 1.20 or later.
Api still needs fixing, but this will get filters running.

The hook 'AbuseFilter-interceptVariable' can be used
for intercepting any request to recalculate a variable,
and if a handler is returning false the later code
will be skipped. That makes it possible to avoid using
content if the content model is wrong, as it could be
for a Wikibase entity.
The hook uses the same arguments as the hook
'AbuseFilter-computeVariable', thereby making it simple
to move handlers around.
The arguments to the hook are
@param string $method
@param AbuseFilterVariableHolder $vars
@param array $parameters
@param AFPData|array|int|mixed|null|string &$result
Patchset 2: Fix for arg 1 to the hook, it got $this
instead of $this->mMethod

Patch Set 11: Merged https://gerrit.wikimedia.org/r/24701 into

Instead pass the Article object from the EditFilterMerged hook to the AFComputedVariable object and see whether the object is present to do a parse operation since other code paths won't pass an Article object
Also simplified the fallback code in AFComputedVariable::compute() to simply continue instead of calling the function again.
ATTENTION! This may break filters that rely on "added_lines contains 'bla-bla'" syntax. They'll need to be replaced with "string(added_lines) contains 'bla-bla'"
