PHP7 throws an Error, not a BadMethodCallException. We don't want to
clog the logs with fatals, now that PHP7 is closer.

We don't need to call it in the constructor, as long as the call in
setUp() is moved to before we start adding groups and checking blocks.

We didn't check if the provided ID was valid. While editing an existing
filter (or creating a new one), we check the ID in SpecialAbuseFilter,
so it's guaranteed to get an integer in ViewEdit, and the case of a
non-existing filter is handled later, in buildFilterEditor.
But for links like Special:AbuseFilter/history/foobarbaz/item/1 (where
"foobarbaz" should be the filter ID), no validation was performed. This
caused a useless query to be carried out on the abuse_filter_history table (which would likely return false), then accessing properties of a non-object ('$row->afh_id'), and we ended up showing filter 1. This was spotted because we actually got notices in production.

There's not need to use the variableholder in this hacky (albeit common)
whay, since the row already holds the action.
Note, this doesn't guarantee that the next two lines won't fail - I'd
need to see the actual var dump (T231542#5450720) to determine exactly
why this is failing.

IMHO these can be considered unit tests; they were already fast, but now
they're executed in an instant.
This requires several changes: 1 - delay retrieving messages in
AFPUserVisibleException, to avoid having to deal with i18n whenever we
want to test exceptions; 2 - Use some DI for Parser and Tokenizer.
Equivset-dependend tests are also moved to a new class, thus helping to
fix the AF part of T189560.

This dependency is wrong, and removing it will also allow creating an

Some of these are transformed into real unit tests, while the
AbuseFilterSaveTest class is refactored to avoid using the DB and to use
a lot more of mocks and DI.

There are lots of calls to $user->isAllowed which could be simplified
using available accessors like canEdit(). So simplify those calls and
avoid duplication.
Note that using canEdit also fixes a bug which affected blocked users:
we used to show e.g. the import link, and not to display as disabled
several text fields, while blocked users cannot actually edit filters.

There are lots of cases where we can inject a User object without
additional efforts. Now $wgUser is only used inside AFComputedVariable,
which is a little bit harder to handle because some instances of that
class are serialized in the DB, and thus we cannot easily change the
constructor until T213006 is resolved.
This partly copies what Ia474f02dfeee8c7d067ee7e555c08cbfef08f6a6 tried
to do, but adopting a different approach for various can*() methods:
they're now static methods in the AbuseFilter class, so future callers
don't need to instantiate an AbuseFilterView class. This also allows to
re-use those methods in an API module for editing filters (T213037).

While this is not as important as throwing for too few parameters, IMHO
it's still important to fail in this case. Mostly because if a function
receives too many parameters, chances are that who wrote the filter
didn't do that intendedly, and thus there may be a hidden bug.
Bonus: fix a few docblocks.

In general, it's not safe to change configuration in the middle of a
test, because services could wind up in an inconsistent state. In
particular, I'm trying to have setMwGlobals() reset services, which will
cause stuff to break if it happens in the middle of a test. So just
specify the settings you want up front, like in setUp().

For now it will only report successful parse. Next step is formally
deprecating the old one (escalated to warning), then removing it in
favour of the new one (in another MW version).

This allows a little bit more of abstraction: we can store other data in the
tree, without having to store it in a specific node (e.g. the variables map,
which is still unused). It also adds a few typehints, and specializes
the return value of eval'ing the AST: previously, it was the one of
evalNode, which wasn't guaranteed to be an AFPData. Now we have this
guarantee. Last but not least, we can now measure runtime metrics for
evalTree, which doesn't recurse.
Bonus: fix a check in the old parser, which used the wrong variable when
reporting outofbounds errors.

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)`.
