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.

Pass the full ref structure from ReferenceStack to FootnoteMarkFormatter,
to give it control over the final rendering. This is aligned with how
the FootnoteBodyFormatter directly scans over groupRefs.

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 was a bug which would affect book references, if the same group
and parent ref name combination occur twice in an article.

This patch does two things:
* Add strict PHP 7 type hints to most code.
* Narrow the interface of the checkRefsNoReferences() method to not
require a ParserOptions object any more.

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 ...`

There was a call in the API that was *not* using normalizeKey(). Now
that the API is gone, we can inline this.
This patch also contains a bunch of cleanups that might already been
resolved in the previous patches.

Forked from Icd933fc983.
Bugs and unimplemented features are documented as TODOs in the parser test
fixtures.

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.

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.

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
and consistent.
* getGroupRefs() won't fail any more when asked for an unknown group.
Tests:
* 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.
