Thiemo Kreuz 99ee9e443b Rename $valid to $status for clarity
This also splits some code a little bit to make the next patch smaller.

Thiemo Kreuz 0013943a4a Rewrite argument parsing and use for both <ref> & <references>
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.

Thiemo Kreuz 99d23ac841 Remove redundant attribute trimming
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.

Adam Wight 7cdcc2b075 Alphabetize returned array of attributes
That was annoying me.  Since we're passing a bare list, alphabetical
order helps make the code and tests readable.

Adam Wight 22b0bdf526 Test for numeric extends attribute
This is invalid, because it would allow access to internal, autoindexed,
anonymous refs.  These would break when refs are reordered.

Adam Wight feaa724efa Test for numeric attributes earlier
This introduces a slight behavior change, but for the better:
* When pointing to the name "0", the non-numeric error will be displayed,
  which is correct whereas "no key" is not.

Adam Wight 8453e3ecd7 Extract stack and state to a new class
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.

Thiemo Kreuz (WMDE) 5401fcd190 Revert a part of "Add missing test cases for follow="…""
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.

Thiemo Kreuz c76a5e84f9 Fix misleading method names in CiteErrorReporter
I realized especially the method name html() was wrong. It does not
return HTML. What it returns is still wikitext and must still be parsed.
It only applies some early steps of the parsing process, e.g. expanding
extension <tags>.

Thiemo Kreuz 177c9cc1eb Fix inconsistencies and deep nesting for follow="…"
* 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".

Thiemo Kreuz a823fa23d9 Merge two more code paths in Cite::referencesFormatEntry()
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.

The goal here is to reduce the number of code paths to make it much
easier to implement proper rendering for the extends="…" use cases.

Thiemo Kreuz 8e42a6ecdf Add missing test cases for follow="…"
One of the test cases was duplicated, but a lot of the possible code
paths never had tests, including the happy code path!

I found this issue while trying to rework some of the more confusing
loops in this codebase. These changes are still part of this patch. All
loops still do the same as before, but are (I hope) more readable now.

Thiemo Kreuz ea6cea93ed Move bad dir="…" error reporting down to the renderer
… 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.

Thiemo Kreuz 65c8967c32 Fix internal presentation of the dir="…" attribute
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.

This patch does intentionally not touch any file name. Some of the

easily be renamed in later patches.

I used https://codesearch.wmflabs.org/search/?q=new%20Cite%5C( and it
