Ensure that the variable isn't set before marking it as DUNDEFINED:
that's only for when we cannot use a default, but if the variable is set
we already have one. Most notably, this fixes conditionals handling: right
now, if you have a conditional with an assignment in both
branches, the variable will be undefined. That's obviously wrong, so
it's fixed in this patch.
Plus: catch only AFPExceptions in a test to avoid unintentionally
catching the assert exception; simplify some assignments using wfSetVar.

This patch includes various fixes to how func arguments are handled in
CachingParser:
- Add a comment about a future improvement of checkSyntax, which we
could limit to try building the AST.
- Having enough args for each function is now also checked when
building the AST. This allows implementing the previous point without
stopping to report notenoughargs at syntaxcheck-time (otherwise it'd be
a runtime error). And it also ensure that we check for the params count
inside skipped branches, e.g. inside if/else: these were already only
discovered at runtime in CachingParser. The old parser is not affected
by this change, because when checking syntax it will always execute
all branches, and at runtime it will skip braces altogether.
- Fix arg count for CachingParser, which previously added a bogus param
in case of a function called without parameters. This was fixed for
the other parser in I484fe2994292970276150d2e417801453339e540, and I
just ported the updated fix. Also note that the CachingParser was
already failing for e.g. `count()`, but instead of complaining about
missing arguments, it failed hard when trying to pass NULL to
evalNode.
- Fixed some tests not to use setExpectedException, which caused the
previous point to remain unnoticed: calling that method prevents the
loop from continuing, and thus only the AbuseFilterParser part was
being executed. The new implementation checks the exception ID and is
thus more future-proof if the i18n message changes.
- Fixed some function names in error reporting for the old parser.
- The arg count is now checked outside of the function handlers, thus
it's no more necessary to call checkEnoughArguments at the beginning
of each handler. This also produces clearer error messages in case of
aliases (e.g. set/set_var).
- Check the args count even if some of the args are DUNDEFINED. This is
much easier now that the check is outside of the handler. This will
make syntax check fail for e.g. `contains_any(added_lines)`.

The regression itself was fixed in
I980aec3481a52ecc35f1811a366014a5581a7cdb, so this patch only adds a
test for it.
Also remove a comment about CachingParser failures: we don't want to
encourage people to remove it from tests anymore.

Just like we do for functions, it doesn't really make sense to have
keywords separately, in AFPData.

This is more complicated than the := operator, because the var name
could be a complicated expression, and we have to handle a function
call. This patch only covers the case where the variable name is a
literal, which is enough for WMF production.

As for all mostly unused consequences, blockautopromote has a couple of
major problems: first, it blocked the status for a random time between 3
and 7 days, which to me makes no sense at all (is it some sort of
casino?), and this patch fixes it to 5 days. Second, nothing was logged,
not the blocking nor the unblocking. Here I'm adding a LogHandler for
two new sub-actions of 'rights' to keep track of both action.

Note: Here I'm adding a FixMe for a problem which already exists in the code
and the child patch will fix it.

I5ec4ab44c4e88aaf18c0d7b73355d27050beeda7 almost fixed this bug, but we
also have to make it possible to access builtin variables as arrays.
This will only make sense for a few variables (e.g. added_lines and
removed_lines), but I don't think we should validate it when checking
syntax.

They're currently stored separately, so move matches count together with
other per-filter data to keep it consistent. This also removes a
parameter from filterMatchesKey, as it's not needed anymore.

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.

Added in I5a14d4b2bc3ffd9caaaa095f16f36b9b6009db05, but .r files aren't
used anymore since I6c06e596587750c4ebaabafbd277bc75eeb436a5, and I
forgot to remove the file upon rebasing.

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.
