AbuseFilter::getConsequencesForFilters uses filter ids as
array keys, that causes problems if both local and global
filters were hit, because array_merge reindexes arrays.

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!

$wgAbuseFilterAnonBlockDuration didn't default to the actual
value of $wgAbuseFilterBlockDuration but to the default value
of that (which is indefinite). Fixed that (untested)

During testing the context does not always contain a valid
Title object. In those cases AbuseFilter will fail hard.
This changeset makes the filter survive some of those
failures.

This creates a $wgAbuseFilterAnonBlockDuration, which
allows for IP blocks to have a different length.
For backwards compatability this is default set to
$wgAbuseFilterBlockDuration.

Currently $wgAbuseFilterDisallowGlobalLocalBlocks checks against a
hardcoded list for "block actions", which means that extensions
like GlobalBlocking cannot add actions to it.

The title in the context provided for an edit may be a special page
in some cases, e.g. when an extension uses a special page for creating
new content, and the final name of the content is not yet known
when the EditFilterMergedContent hook is called.
This change will allow special pages to be used in this context.

On top of that I changed /history to no longer show the
changes link if it's the first revision of the filter.
As I was on it I fixed the diff selection for diffs like
history/1/diff/2/next where change number 2 was compared
to the last change of the filter instead of the next one.
This probably went unnoticed because the /next action isn't
linked anywhere within the software itself.

This changes the AbuseFilter to use Status objects for internal
error handling. This allows for more flexibility in passing error
messages back from hooks and avoids double escaping.
Change-Id: I72e1a6dd7dee19f889fc13b60456e9bfebd5e22b
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.

If $wgDisableCounters is set, using the variable will result
in a syntax error for an undefined variable.

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 concept of different AbuseFilter groups had not properly been integrated, but should be now:
- The total number of matches is now group-specific
- .. Which will also fix the emergency shutdown calculations
- And a portion of incorrect code (involving $logged_local_filters) has been fixed (action != group)

The link should not be shown to users that don't have the right to use it,
like with the tools and import pages

Added two hooks to the AbuseFilter, one that allows altering of the
variables created for a specific user and one for title specific
variables. This a much cleaner way to add title or user specific
variables than using the current general-purpose hooks.

This patchset will make it possible for other extensions to tap into abusefilter with a custom group, and set different tresholds per group.
