Adam Wight 8097c4c148 Split validation function depending on inReferencesGroup
Some validation is exclusively used in a specific context, some is shared.

Thiemo Kreuz c5fe49ff11 Fail early on nested extends="…", if possible
This partly reverts Ied2e3f5. I haven't properly tested this before.
Rendering a bad extends (that extends a <ref> that's already extended)
not indented messes the order up and rips other extended <ref>s out of
context.

For now it might be better to stick to the previous, "magic" behavior:
Such an extends behaves like it is extending the *parent*, and is
ordered and indented as such. This is still not correct, but I feel
this is much better than rendering such a bad extends on the top level.

This patch also makes the code fail much earlier for a nested extends,
if this decision can be made already. In this case the error message is
rendered in the middle of the text (as other errors also are), not in
the <references> section.

Thiemo Kreuz 8fdce945bd Show "Preview" headline in user instead of content language
This partly reverts Id7a4036e64920acdeccb4dfcf6bef31d0e5657ab.

The message "cite_section_preview_references" says "Preview of references".
This line is not meant to be part of the content, but an interface message.
It should use the users (interface) language, not the content language.

Thiemo Kreuz a7ee7c9586 Refine and fix "unclosed <ref> detected" regular expression
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.

Thiemo Kreuz a7c4e14f42 Remove obsolete ParserBeforeTidy hook handler
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.

This makes it obvious that our function isn't sensitive to the input value.

Also rearranges a string concatenation to make the element wrapping clearer.
I probably should have switched to the HTML class here, but I'm not sure what
the advantages would be.

* Narrow the interface of the checkRefsNoReferences() method to not

Adam Wight ffedf86a19 Clean up text and name conditionals
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 ...`

This is motivated by I9427e025e, which demonstrates that the existing
logic was hard to integrate into.  There's a lot of redundant expressions
which make the function difficult to read, and code paths which have
less effect than they appear to.

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 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.
