This patch includes:
* Making it possible to access offsets of a DNONE (returning a DNONE)
* Initializing user-defined variables as DNONE inside short-circuited branches
* Make DNONE propagate with other operators
* Make DNONE count as false for logic operators
* Remove a now-outaded bit in doLevelAtom. In case of shortcircuit,
$result is now DNONE instead of DNULL, and thus it's possible to
access offsets of it. Performance++!
* Don't allow modifying or adding an element of a DNONE as if it were an
array (to avoid inconsistencies)
This re-applies Id85c673337fa90a3782fd22eb9690cd996967111 with several fixes.
NOTE: Haven't tested locally, although I'm pretty confident thanks to
the amount of tests added.

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.

This should allow more flexibility when checking syntax, and a saner
behaviour overall.
Aside from not throwing exception in certain cases, the results should
be almost equal to the ones you would get without this patch. However,
there are still a few things to improve (which for convenience I wrote
inside the parser test) and many to test.

Aside from the 14 thingy reported in the task, this syntax is awful! The
fix to the regex should only be intended as a temporary stopgap. A
proper fix would be to introduce a new syntax, like for instance the one
used in PHP.

This property is meant to be private, since it has all kinds of
getters/setters, aside from one which is introduced in this patch.

The current form is awkward. They're all like
[ actionname => [ 'action' => actionname, 'parameters' => params ] ]
This is greatly confusing since adds a nesting level, and just
duplicates the actionname information (also, we actually never retrieve
it from the internal array). Instead, change all of them to be
[ actionname => params ]
which is a lot shorter and clearer (and easier to handle).
A similar case is handled in I8134ecc41fbecdbed99faf406e9e3ca91b6123b9
(see PS 8..10).

As explained on phabricator, they don't work with shortcircuit, so they
already fail for all filters using them. Plus IMHO it's an unnecessary
deviation from PHP's behaviour, given that this syntax doesn't do what
users may expect.

Using the new PageEditStash class allows to simplify a bit the
integration tests for edit stashing. As I wrote in a ToDo, it may be
enough to manually run the hook, but that's left to do as a follow-up.

Instead of relying on static methods and members in the AbuseFilter
class, move everything related to conditions inside the Parser, as the
amount of used conditions is something pertaining a single
AbuseFilter(Caching)Parser instance.
This change requires changing some signatures and adding parameters,
but will make introducing the new AbuseFilterRunner class easier (and
that will clean signatures, too).

Now it returns an array with a bit more info, and has a different name
to reflect the fact that its input is now split in two parts. Plus, make
it throw whenever it gets an unexpected input, and add a bunch of test
cases for it.

Partial revert of I4dd81a723e2bdb828b90594ad66a3918d8ec5b6c.
Thinking again of it, I think it's not worth it to have this data over
the network. Plus, given that it's not-that-slow to be computed, I think
there can only be a performance gain in using APC (as opposed to e.g.
memcached/redis) for 99.9% of the filters.

Added cachingParser back to *all* the parser tests, fixed a couple of
differences with the normal parser, and added a couple of tests so that
any cachingParser-related file has 100% coverage. Also move the remaining
get_matches tests inside parserTests, and specify the parser used in case of failure.
This also adds a new base class for parser-related tests with a couple
of util methods.

Another crucial part to have covered. Also clarify that
AbuseFilterCentralDB can be of the form "dbname-prefix".
Remove a filter used for profiling and replace it with a global one:
we're still fine, and the list is kept shorter.

Yet another important part to have covered. While for normal edits it
already works, for stashed ones it doesn't. That's why we need the patch
for checkAllFilters. Since for stashed edits profiling stats are all
zeros, this may explain T201334.
Changed the timestamp variable to use wfTimestamp instead of time() so
that we can fake it inside unit tests.
In a subsequent patch we should add average runtime conditions to tests
(really tricky).

I find it obvious that a file called "AbuseFilterTokenizerTest" is a
"test for the AbuseFilterTokenizer class". A comment that is just
repeating this information is typicalls not helpful, but distracting
and a potential source of mistakes, e.g. when stuff is copy-pasted,
but the comment not adjusted.

Caching the result of the tokenization is pretty important
performance-wise, so this test ensures that caching works as expected.
I have also extracted the method used to generate the cache key for
easier testing, and moved the cache instance to a class member because
otherwise that piece of code can't be tested...

These are the ones which other tests don't cover, mostly because no
filter syntax can trigger those cases. This patch should bring coverage

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.
