It's debatable if this is an error. I'd say it's more like a warning.

refactor preference cookie handling. fixes #4544

This refactors the DOKU_PREF cookie handling on the PHP side into a
class. It makes encoding/decoding more explicit and easier to
understand.

The new class is used in set_doku_pref() and get_doku_pref() which have
not been deprecated for now.

set DOKU_INC in rector

Add experimental tree builder classes

These classes provide mechanisms to build a traversable tree of pages
and links. Either from the existing namespace structure, or from a
control page containing (possibly a nested) set of links.

The nodes returned by the tree are deliberately sparse. No ACL checking
is taking place. Developers can enrich (or omit) nodes and influence
recursion decisions via callbacks.

The tree can optionally be sorted by comparators provided in the
TreeSort class or a custom callback.

The API provided by these classes is not considered stable yet and may
change over time. Plugin authors are encouraged to use them and provide
feedback.
