This simplifies as well as fixes a series of issues with this regular
expression:
* Before, the wikitext `<REF><REF>` would not trigger the error, but
`<ref><ref>` would. Parser tags are case-insensitive, but the error
check was not.
* Before, the wikitext `<ref><ref name="<">` would not trigger the error.
That's a valid name. The error check should not stop just because it
found a `<`.
* Both the old and the new code do *not* fail with the wikitext
`<ref><ref</ref>` where the inner `<ref` does not have a closing `>`. I
was thinking about changing this, but figured it might be used as a
feature.
* The old code was not able to properly understand HTML comments,
<nowiki> tags and such that contain a line break. That caused
inconsistent and confusing error reporting in some cases, but not in
others. This change *reduces* the amount of errors this code produces.
* The old code was looking for "SGML tags" with names that could be
anything, not just alphanumeric characters. This allowed for strange
edge-cases like `<ref><>><ref></>></ref>` that have not been reported,
but should be. This change *increases* the amount of errors. However,
relevant edge-cases should be extremely rare.
Note the ++ avoids backtracking, speeding up the regex.

We never access Language directly, so proxy its method instead of
returning the full object.
I believe I've found a bug, but not fixing here: the footnote body
numeric backlinks like "2.1" behave as if they were decimals rather
than two numbers stuck together with a dot. So they are localized
to "2,1".

I was able to track this code down to I093d85d from 2012, which was done
right after the ParserAfterParse hook was introduced. I believe the
redundant code path was left to keep the Cite extension compatible with
old MediaWiki versions that did not had this hook yet.
I also noticed this code path is most probably entirely redundant with
the current version of MediaWiki. The *only* thing this code does is
blocking the ParserBeforeTidy hook from doing the same thing a second
time if the ParserAfterParse hook was called before. But it does *not*
block any other compination, e.g. if the two hooks are called the other
way around, or the same hook twice.
In core, it looks like it is impossible for the ParserBeforeTidy hook
being fired without the ParserAfterParse hook being fired before. If this
is true, this is in fact dead code.

The new extends="…" feature is using numbers like "1.2". These should be
localized in languages like Hebrew that uses other symbols for the digits.
But the "." should not change.
The existing feature when a <ref> is reused multiple times does have the
same "issue". But it seems this is intentional, because it is covered by
a test. Note this is not visible in German, because German uses custom
labels "a", "b", and so on.
This patch also improves the so called "smoke" tests and makes one cover
numbers up to "1,10" for a <ref> that is reused that often.

If `extends` is encountered before the parent ref, we reserve the
sequence number and leave a placeholder to record the link between
ref name and number. This is necessary to render a list like,
"[1] [2.1] [2]", or to use subreferencing when the parent ref is
declared in the references tag.
When a placeholder is encountered during references section rendering,
it means that the parent was never declared.

This was carrying the entire footnote marker, but subreferences need
to extract just the first (group ref sequence) part. Storing number
and extendsIndex in two separate fields gives us more flexibility
during rendering, for example these might use two different symbol sets.

This fixes a FIXME I left in the code. Previously, I just stripped the
closing </li> to make sure the nested <ol> is *inside* of the <li>.
This relies on (Remex) Tidy to clean the incomplete HTML up.
This patch remembers the stripped </li> and adds it back.
This also makes sure the nested <ol> is closed, even if it was the
last element in the data structure.
Notice how this does not influence any test. I find this a bit
confusing. It looks like (Remex) Tidy is executed, even if the tests
are not marked as "html/php+tidy".

The "no key" error should have been unreachable, but I'm afraid that
null `$text` and empty string `$text` were reporting slightly different errors.
Unfortunately, we still have to care about `$text = '0'` because PHP, so
the expressions don't reduce to `if ( !$text ...`

which make the function difficult to read, and code paths which have

We realized the trim() are not needed. This does not leave much behind
in the existing refArg() method, except that it checks for unknown keys.
I tried a few strategies and ended using the pretty new possibility to
have keys in list(), as well as use [] instead of list(). Both is
supported since PHP 7.1.

We noticed the group="…" attribute was the only one that was not
trimmed. Does this mean it was possible to have two groups "a" and
" a"? It turns out: no. This was never possible because the parser
already trims all attributes before calling this code.
I tried to come up with the worst possible test case, but it succeeds,
even with very old versions of this codebase.
I suggest to remove the extra trimming from this codebase and rely on
what the parser provides.
Note the content is special and *not* trimmed by default.

Functional changes:
* hasGroup() will return false when a group exists, but is empty. This
is in line with what other methods like getGroups() already do.
Shouldn't have any effect on the existing code, but feels more clean

* Add missing @covers for the constructor.
* Simplify test setup by always returning a spy. All tests need it
anyway.
* Cover 3 more methods.

Most of this state is used to manage interactions with other state,
and encapsulation allows us to hide data structures and access behind
self-explanatory function names.
The interface is still much wider than I'd like, but it can be improved in
future work.
There is one small behavior change in here: in the `follows` edge case
demonstrated by I3bdf26fd14, we prepend if the splice point cannot be
used because it has a non-numeric key. I believe this was the original
intention of the logic, and is how the numeric case behaves. I've verified
that when array_splice throws a warning about non-numeric key, it fails to
add anything to the original array, so the broken follows ref disappeared.

This partly reverts commit 8e42a6ecdf.
The variabe $k as created by the foreach() loop is not necessarily
numeric, because the $this->mRef structure contains data both for
named and unnamed <ref>s. The array key is a (non-numeric) string for
named, and an integer for unnamed <ref>s.
array_splice() requires a position, not an array key.
Note that both implementations are wrong. The foreach() might return a
string $k, which makes array_splice() complain and do unwanted things.
The for() loop assumes there are count() array elements with integer
keys, which might not be true. Luckily this was not a problem, because
the isset() check would stop the (to long) loop eary enough.
A better rewrite as well as a test case for this will be added with
I3bdf26f.

It only applies some early steps of the parsing process, e.g. expanding

* This fixes the refArg() function. If there is nothing wrong with the
follow="…" attribute, it should not return null.
* However, *everything* is false if an unknown error (e.g. an unknown
attribute) occurs.
* A trivial check for `if ( $follow )` is fine because all keys are
guaranteed to not be the string "0".

There was another, duplicated special case for previews. It was using
the same message as a <ref> with multiple uses. Now it's only one code
path.

… and make the error message for bad dir="…" shorter and more to the
point.
Now I understand why the error reporting was not done when $text was
empty: the error was actually appended to $text, which messes with
everything else that also works with the $text variable! This even
includes the API. This error message was exposed via the API. That was
certainly a bug.
With this patch, all error checking for the dir="…" attribute is now
done way down, when rendering the <references> section.
Note this also fixes a bug where the dir="…" was *not* rendered when
previewing a section.

This fixes a whole bunch of inconsistencies:
* The dir attribute is now trimmed, as most others already are. This is
an actual user-facing change.
* The internal representation is now false in case the value was invalid,
not an empty string any more.
* Null means the attribute was not present. This is now always used,
even in the return values that are meant to represent an error state. No
existing behavior changes.
* The internal representation does not contain an HTML snippet any more,
but the raw value "ltr" or "rtl", or null. Note this might influence the
API, because the API actually exposes the internal representation.
However, we are pretty sure the API is not used anywhere. Even if,
exposing HTML code was most certainly an unwanted and unexpected effect
of the patch that introduced the dir attribute. This does make this a
bugfix, I would argue.
