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)`.

This was broken in I34c040dbeb3ab01158fb3db22496def6ccaf72d9. I thought
the members of that object were always arrays, but I was wrong.
Plus typehint a few array parameters and make a couple of methods
private since they're only used in this class.

Now it's always wider, and so is the "notes" field. Moreover, the
fallback textarea has the exact same size. Plus removed a parameter
which only made it hard to write a CSS rule for the textarea. Since the
textarea is generated by the same code, and we're always using it for
the same thing (filter syntax, regardless of the final goal), make it
always use the same name.

Problems fixed:
- Don't hardcode duration in the message
- Move duration to a constant
- Fix wrong parameter order for AbuseFilter::blockAutopromote
- Log a warning if we cannot block autopromotion
- Remove the $performer parameter, as it should only and always be the
filter user.

If $parser->parse returns a falsey value (=null), that's because the
filter doesn't have any statement. But that's not a valid reason not to
cache the filter. Hence, return whatever parse() is returning inside the
callback, so that the result is always cached.

In order to bundle AbuseFilter, we have to provide an optimal
configuration for sysadmins. This patch aims to provide such
configuration, and of course it's open to changes.
Changed values:
*Grant abusefilter-view-private to admins. This is mostly for
redundancy-safety (they already have -modify)
*Grant modify-restricted to admins (see T200032)
*Disable the 'degroup' action. This is really dangerous, not ideal to be
enabled by default.
*Grant the abusefilter-revert right to sysops. This is similar to
assigning the modify-restricted right in its rationale.
*Add abusefilter-log-private to viewrestrictedlogs grant. This right
should go together with abusefilter-view-private. (T226987)
*Remove abusefilter-revert from the rollback grant, as that right is
for reverting AF actions and has nothing to do with rollbacks.
This mostly copies the config of WMF production: degrouping is already
disabled there, and modify-restricted should
be assigned to sysops on WMF wikis as well. The assignment of the
abusefilter-view-private and abusefiliter-revert rights is handled in
I09cb462312c5bbc71ee3a8f0fbd91357908130d4 (parent patch) to keep the
status quo.
NOTE: this patch should be *deployed* together with the config patch to
avoid discontinuities. Thus, please ONLY provide a virtual +2 using a
+1, and I'll coordinate the +2 with a deployer.

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.
Change-Id: I208a9b1ce2bd12038e9fbcc515c48d604ec80eb8
This patch keeps the current behaviour for everything (since DUNDEFINED
was always casted to boolean false), but handles the cast at a higher
level instead of relying on what AFPData::castTypes will do. This way
it's easier to spot places where we may get DUNDEFINED, and decide how
to handle them one by one.
