Currently we strongly abuse (pardon the pun) the AbuseFilter class: its
purpose should be to hold static functions intended as generic utility
functions (e.g. to format messages, determine whether a filter is global
etc.), but we actually use it for all methods related to running filters.
This patch creates a new class, AbuseFilterRunner, containing all such
methods, which have been made non-static. This leads to several
improvements (also for related methods and the parser), and opens the
way to further improve the code.
Aside from making the code prettier, less global and easier to test,
this patch could also produce a performance improvement, although I
don't have tools to measure that.
Also note that many public methods have been removed, and almost any of
them has been made protected; a couple of them (the ones used from outside)
are left for back-compat, and will be removed in the future.

As all title variables would be null, and the result pretty meaningless.
NOTE: Please vote V+2 and submit manually. I359a618ffc4e45ce1fb70f2d

two more patches just for a handful of tests being broken for a minute.

Remove a filter used for profiling and replace it with a global one:

The reasoning is similar to the one of the parent patch (Ia5c477edc8733bb1994cb6d01e1371ed496c8bcb). Plus, it records runtime metrics on action different than edits, as there's no reason not to do it.
No performance issues in production.

This variable was introduced to selectively enable profiling because
stats recording was bad for performance. Nowadays, stats are recorded in
a deferredupdate and don't harm performance anymore. Thus, this variable
can be removed and profiling be enabled by default.

Since double-equals are evil. I left some of them in place where I
wasn't sure, but I may be changed some which were intended to be
doubles. It could be a good idea to delay merging this patch until we'll
have more code coverage.

The uppercase is just a leftover from a long time ago. Currently,
variables are case-insensitive, and we already perform a strtolower when
saving them. Since most parts of the code already use lowercase, the
uppercase leftovers only make it harder to grep the code to find
variables. As a bonus, make Ace recognize variables in a
case-insensitive fashion.

This patch adds missing methods for testing a filter against uploads in
RC. Please note that (as discussed below) using wfFindFile could be
relatively expensive (as it will be executed for 0-100 RC rows).
If this is true, then we should either use another method (but I
couldn't find a suitable one), or simply reduce the amount of testable
uploads to a reasonable limit.

Tagging doesn't work for account creations, and probably never did. This
is because we used a wrong identifier for such actions. This patch fixes
the problem, although in the long term we should find a smarter way to
apply tags.
Also, clean AbuseFilter::$tagsToSet if the action will be prevented.

This is an old leftover, used to add global JS variables in a convoluted
way: using a hook and a total of 3 static properties. We can safely
remove all of this and just call OutputPage::addJsConfigVars, which BTW
is already called where we need it.

As follow-up of I10b1fd2d9bdfe518089c053d77fef568170ecb65, use
'AbuseFilter' instead of 'AbuseFilterDeprecatedVars' as channel name.
Raise level for null-title filtering. Since with a null title
several things are likely to break, a warning is more appropriate here.
Tweaked the message as well, to include the bug number and to avoid
pointlessly including the title (which is null).
Lower the level for stashedit hit/miss (as it's really spammy and not
that useful right now).
Use 'abusefilter' instead of 'AbuseFilter' for statsd so that everything
has the same prefix.
Also raise the level for parser exceptions and unrecognized
consequences.

Otherwise calling bufferTagsToSetByAction multiple times makes the list

The variable was disabled with I7f13773766e12f3d4b86451fdf3ae23e067ac373
in 2016, but not in the same way as old_text and old_html were disabled
in 2009. This patch uses the methods introduced with
Ife168522e6b1d8eb94ebbb8a16ae8831ec1dc497 to disable minor_edit in a
standard way, so that it won't be showed in new AbuseLog entries, and
won't be usable when writing filter syntax.
A warning will be emitted if a pre-existing filter is using it, so that
we'll be able to completely disable it in the future.

We have two situations where we try to execute filters without a title.
However, the code doesn't handle it correctly: some points expect $title
to actually be a Title object, and we also pass it around using a hook
which explicitly says it always pass a Title. This patch adds two debug
points to help understand why we end up with null titles, so that we can
fix it upstream.

For several reasons:
*We're not really checking permissions (and the hook previously used is
meant to be used in such case)
*We'll show a cleaner error message (i.e. without the "You do not have
permission..." part)
*Filtering will happen closer to the actual move

moment this is still fine due to temporary overrides in
AbuseFilter::generateTitleVars, but this should be merged ASAP anyway.

Variables regarding title (full list in task description) are quite
deceiving, since they use "text" instead of "title". As proposed in the
task, this is the first patch to add aliases for those variables and
slightly deprecate the old ones. In the future we may be able to replace
every occurrence (either with a search function or directly on the
database), but even a coexistence would be enough to avoid
confusion. A wfDebug log is generated whenever a deprecated variable is
parsed. The "article_" prefix is also changed to "title_", in the same
way as above.
Also, added a hook which other extension may use to specify their
deprecated variables, which will be handled the same as core ones.

This fixes the following minor issues:
* In HistoryPager's getQueryInfo, afh_id was listed twice
* In AbuseFilter::translateFromHistory a field named "af_" was produced
if no actions were in use
* The topnav link "Recent filter changes" wasn't STRONGed on pages like
"Special:AbuseFilter/history/123"
* In checkAllFilters and AbuseFilter::getFilter, select from DB only the
fields that will be used.
* Simplify some inline comments and remove superfluous ones
