Allows the "refines" attribute when the feature flag is set, but doesn't

with invalid wikitext in case of undeployment.

* I used https://codesearch.wmflabs.org to make sure the private
constants are indeed not used anywhere.
* The added type hints are safe, as far as I can tell. There is no way
one of these parameters can contain anything else. Otherwise the code
would fail already.

Collect EventLogging metrics for footnote and reference link
interactions, so that we can compare behavior with and without
Reference Previews enabled.
This tracking will be reverted once analysis is complete.
A mostly arbitrary sample rate of 1/1000 is hardcoded here. This is
loosely based on the latest tuning of Popups sampling at 1/100,
divided by a conservative factor of 10 to ensure headroom.
The sample is skewed by skipping clients without sendBeacon support,
but we're avoiding the mw.track synchronous fallback, which injects an
image tag and introduces lag any time the user clicks external links
in the references.

We can resolve this bug by either replacing the bogus "return false"
with the intended "return [ false, … ]". Or rely on the code a few
lines below that also bails out with a "return [ false, … ]" when to
many parameters ($cnt is not 0 then) are present. The tests prove both
solutions are equally valid.

The biggest issue with this code was that it was tracking the exact
same state in two ways: Processed array elements got removed from the
$argv array, *and* the $cnt was decremented the same time. This is not
necessary and a potential source of confusion and errors.
I carefully transformed the code. I'm sure it still does exactly what
it did before. The tests should prove this.

This change does have two consequences:
1. A few more whitespace characters act as separators. This should not
have any consequence in real life situations, and is mainly done to
make the code easier to read and less surprising.
2. Sequences of two or more whitespace characters previously resulted
in partly *empty* results. This was a potential source of errors. The
additional + fixes this.

Core sanitizes link targets and removes double spaces and underscores.
But the corresponding id="…" attributes are not sanitized the same
way. This results in broken links. This patch is not perfect (two
references with name="a_b" and name="a__b" will conflict), but the
best solution I can think of at the moment.

Because of how arrays are handled, phan-taint-check thought all
return values from refArg() were escaped, where really only $dir
was. We also split the error method into the parse and noparse
case as separate functions so that phan can better analyse these calls.
In linkRef() we suppress the double escaping as the escaping used
is appropriate for inserting into wikitext.

The Cite extension already had a recursion guard around the parsing of
`<references/>`, to prevent another `<ref>` containing `<references/>`
from producing a weirdly nested references list.
When an explicit `<references/>` tag is not included in the page, or
`<ref>` tags exist after the last explicit `<references/>`, the extension
automatically adds a reference list at the end of the page, to make the
references still displayed.
This automatic references list creation was bypassing the recursion
guard, causing the weirdly nested output *and* a PHP Notice from
`mRefs[$group]` becoming undefined. This commit sets the recursion guard
state during that automatic references list creation to prevent this.

The motivation for this patch is to make the code less complex, better
readable, and less brittle.
Example:
public function onExampleHook( Parser &$parser, array &$result ) {
/* This is the hook handler */
}
In this example the $result array is meant to be manipulated by the
hook handler. Changes should become visible to the caller. Since PHP
passes arrays by value, the & is needed to make this possible.
But the & is misplaced in pretty much all cases where the parameter is
an object. The only reason we still see these & in many hook handlers
is historical: PHP 4 passed objects by value, which potentially caused
expensive cloning. This was prevented with the &.
Since PHP 5 objects are passed by reference. However, this did not
made the & entirely meaningless. Keeping the & means callees are
allowed to replace passed objects with new ones. The & makes it look
like a function might intentionally replace a passed object, which is
unintended and actually scary in cases like the Parser. Luckily all
Hooks::run I have seen so far ignore unintended out-values. So even if
a hook handler tries to do something bad like replacing the Parser
with a different one, this would not have an effect.
Removing the & does not remove the possibility to manipulate the
object. Changes done to public properties are still visible to the
caller.
Unfortunately these & cannot be removed from the callers as long as
there is a single callee expecting a reference. This patch reduces the
number of such problematic callees.

This is the default for many years now. Returning true does nothing. It's
identical to returning nothing (null). The only meaningful value a hook
handler can return is false, and even this is meaningful only for very
few hooks.
TL;DR: A "return true" in a hook handler is always meaningless, dead code.
I'm interested in this because we (WMDE) might start working on this
extension soon and I want the code to be small and easy to maintain.

This was briefly enabled in WMF production in 2009 and found not to work.
As far as I know, it's been disabled since then. Retaining it requires
maintaining the complex "half-parsed serialization" feature in the core
parser, which I'm deprecating in I838d7ac7f9a218. The core feature was
added solely to support this Cite caching experiment and is not used for
anything else.

Line 334 of Cite/includes/Cite.php contains two preg_match () calls. The subject lines for them are produced by Cite::refArgs () and are set to null or false when no name or follow attribute is provided in the <ref></ref> tag.
However, preg_match () is supposed to accept only strings as its subject, and the nowhere in the documentation it is said that it is nullable.
At least, in HHVM 3.12 this causes an exception.
The enclosed patch adds simple checks making sure that preg_match () is not called when $key or $follow are null or false.

This is based on the popular 'count' parameter from Template:Reflist on
English Wikipedia, which has also been adopted by many other wikis.
That template's 'count' parameter allows maximum flexibility on a per-
page basis. This was important because the template can't know how many
references the list will contain. Users typically manually add (and
later, increment) the 'count' parameter when the list exceeds a certain
threshold.
The template currently sets an exact column count (via the CSS3
property `column-count`).
This patch improves on that by instead using the closely related CSS3
`column-width` property. This automatically derives the column count
based on the available space in the browser window. It will thus create
two or three columns on a typical desktop screen, and two or no columns
on a mobile device.
The specified width is the minimum width of a column. This ensures that
the list is not split when rendered on a narrow screen or mobile device.
It also hooks into the raw list before parsing and adds the class only
when the list will contain more than a certain number of items. This
prevents very short lists from being split into multiple columns.
Templates like Template:Reflist on English Wikipedia currently are not
able to set inline styles on the list element directly, which is why
they set it on a `<div>` wrapping the `<references />` output. Because
of this, the feature of the Cite extension must not be enabled at the
same time, as that would result in both the template's wrapper and the
references list being split. The end result would involve sitations with
three columns split in four sub-columns, creating a complicated mess of
nine intermixed columns.
To provide a smooth migration for wikis, this feature can be disabled by
default using `$wgCiteResponsiveReferences = false`. Each individual
template createing reference list can then be migrated, by removing the
wrapper column styles and instead settting the new "responsive"
attribute, like so: `<references responsive />`.
Once any conflicting templates have been migrated, the default for the
wiki can be swapped by setting `$wgCiteResponsiveReferences = true`.
If wikis wish for some templates to keep their custom column splitting
behaviour, templates can also opt-out by setting `responsive="0"`, which
will make sure that it will keep behaving the current way even after the
feature becomes enabled by default for the wiki.
In summary, when disabled by default, pages can opt into this system
with `<references responsive />`. When enabled by default, pages can opt
out of the system with `<references responsive=0 />`.
* Deprecate cite_references_prefix/cite_references_suffix.
This message is rarely used and opens up compatibility hazards.
It was already removed by Parsoid, but the PHP implementation
still had it. It's typically used to add inline styles to the
wrapper which is more appropiately done in Common.css (or
obsoleted as part of the skin or Cite extenion itself nowadays
depending on what style in question).
It was also a HTML-style message with separated open and close
segments, which is an anti-pattern in itself.
* Declare module target explicitly and include mobile. The absence of
this stylesheet caused subtle BiDi/RTL bugs on mobile.
