This problem have been making filters potentially fail silently since
2009. Also add tests for arrays to make sure that no problems arise
when short circuit is used.

This will make tokenizer almost fully covered. The only uncovered parts
are the one with cache and an else condition which I think won't ever be
executed, and thus added a comment for that. Also, remove an obsolete
xxx comment from ComputedVariable (fixed in
I8e420f0259ef6c9e579f7a00beb58f28af9da37d)

Add some tests and improve others to raise coverage percentage. This
should lead to almost 100% for the AbuseFilterParser class. Aside from
this, a couple of changes:
* Remove an unused function
* Let equals_to_any return a genuine result with empty strings
* Remove an if which will never be true in skipOverBraces, since the
function is called after checking the same conditions.

Arrays were introduced with the name "lists". While it **may** look
user-friendlier and so on, it actually uses a wrong name: lists are
different from arrays. I ran a grep and I should've replaced
every occurrence, plus everything seems to work, however a double check
wouldn't be bad.

I added on MW an example of comparison with empty array, which we should
keep inside the dedicated test as well.

Introduce a new function which can be used to group multiple comparisons
in a single condition. In particular, equals_to_any(S, A, B) is the
equivalent of S === A || S === B. This is especially useful in checking
for multiple namespaces, as proposed in the Community health initiative.

I left as ToDo the checks between an array and something else. With this
patch, it'll work like PHP: the result will be true iff the comparison
is loose, the array is empty and the other operand is either false or
null.

Some of them are actually too simple, and may be unuseful in tricky
situations. This patch adds a lot of test cases to provide an (almost)
bombproof safety with future patches.

So that type and value will be identical to PHP's ones.

This feature was never implemented. I'm not sure whether we need a way to compare array and other types of variables (left as ToDo), since e.g. in PHP it's always false.

Added the contains_all function, with basically the same role as
contains_any but using logic AND instead of OR. Also added
ccnorm_contains_all, that is the same of ccnorm_contains_any but with
AND mode. Finally, fixed three wrong task IDs.

This filter is fully functional. The old filter is still enabled by
default for a transitional period in case the new one suddenly has
issues.

I am pretty sure all of the behavior documented in these tests is a bad
idea. It is possible that we can fix it since some of those features
are probably unused, but for now those tests will serve as a
documentation of the current behavior.

substr_count() is just as fast as looped strpos() when there are no
matches, and gets faster as the number of matches increases.
Note that this introduces a small change in behavior when the needle
is composed of repeated substrings, e.g. 'asdasdasd' or 'aa', and
haystack is such that the needle can be matched in overlapping
positions, e.g. 'asdasdasdasd' or 'aaaaa'. The old implementation
counted overlapping matches, the new one doesn't. I don't think this
behavior was intentional and I don't think this change will cause any
real problems.

Previously, 'false & a == b' would actually execute the comparison and
count it against the condition limit, while 'false & (a == b)' wouldn't.
They behave the same now.
mShortCircuit was only checked for the most potentially expensive
operations (computing functions and getting variables), all the other
operations on bogus values generated by this would be executed and the
results ignored later.
This probably doesn't noticeably improve performance, but it corrects
how the condition limit is counted.

If we don't map '\-' and '\+' to themselves, the leading slash gets escaped,
and the resultant pattern only matches a literal slash.
