Using an array keyed by term_id allows us to use `isset()` rather than the
slower `in_array()`. In addition, it lets us avoid the use of `wp_list_pluck()`
on large arrays, and helps us to avoid arrays that are unnecessarily large due
to duplicate entries.

`wp_insert_term()` protects against the creation of terms with duplicate names
at the same level of a taxonomy hierarchy. However, it's historically been
possible to override this protection by explicitly providing a value of `$slug`
that is unique at the hierarchy tier. This ability was broken in [31734], and
the current changeset restores the original behavior.
A number of unit tests are added and refactored in support of these changes.
See #17689 for discussion of a fix that was superceded by [31734]. This commit
retains the fix for the underlying bug described in that ticket.
See #31328.

Previously, it was noted that -1 would return all possible results. However, as the value of `$number` is passed through `absint()`, -1 would actually be converted to 1, thereby producing unexpected results.

The existing 'wp_get_object_terms' filter accepts a parameter `$taxonomies`,
which is a list of taxonomy names formatted for direct use in a MySQL IN clause.
This formatting makes it difficult to make use of the taxonomy list in filter
callbacks. However, changing the parameters passed to the existing filter
raises backward compatibility concerns, so we introduce a new filter that
receives a structured `$taxonomy_array` parameter.
We also take this opportunity to correct and clean up some of the documentation
on the 'wp_get_object_terms' filter.

These actions are fired in a number of different places, and in some cases
the tax name is passed, while in others the taxonomy object is passed. This
inconsistency made it difficult for plugins to use the `$taxonomy` value.

When updating an existing taxonomy term that shares its `term_id` with
another term, we generate a new row in `wp_terms` and associate the updated
term_taxonomy_id with the new term. This separates the terms, such that
updating the name of one term does not change the name of any others.
In cases where a plugin or theme stores term IDs in the database, term splitting
can cause backward compatibility issues. The current changeset introduces
two utilities to aid developers with the transition. The `'split_shared_term'`
action fires when the split takes place, and should be used to catch changes in
term_id. In cases where `'split_shared_term'` cannot be used, the
`wp_get_split_term()` function gives developers access to data about terms
that have previously been split. Documentation for these functions, with
examples, can be found in the Plugin Developer Handbook. WordPress itself
stores term IDs in this way in two places; `_wp_check_split_default_terms()`
and `_wp_check_split_terms_in_menus()` are hooked to `'split_shared_term'` to
perform the necessary cleanup.
See [30241] for a previous attempt at the split. It was reverted in [30585]
for 4.1.0.

When terms are entered into the database, term fields are sanitized with
`sanitize_term_field()`. To ensure that the `SELECT ... WHERE` queries in
`WP_Tax_Query::transform_query()` are not broken by overzealous sanitization,
`sanitize_term_field()` should be used in that case as well. This fixes a bug
where a tax_query using 'field=name' would fail if the 'terms' parameter
contained characters (like spaces) that were improperly removed by
`sanitize_title_for_query()`.

Setting 'show_in_quick_edit' to false when registering a custom taxonomy will
hide the taxonomy when editing posts using Quick Edit.
The new 'quick_edit_show_taxonomy' filter allows this behavior to be filtered

type but not for others.

Previously, attempts to descend the family tree of each term were done using
the first taxonomy in the `$taxonomies` array, with the result that terms not
belonging to that taxonomy were not found and their children not properly
parsed. We fix this bug by fetching each term's taxonomy with the SQL query,
and then using that taxonomy to get the correct children for each term.

There is a pre-check in `get_terms()` that prevents an unnecessary database
query if the 'parent' or 'child_of' parameter is not found in the cached term
hierarchy (since a term without an index in the hierarchy cache has no
descendants). Previously, only the first item in the `$taxonomies` array was
being checked, with the result that an empty array was being erroneously
returned in cases where the 'parent' or 'child_of' term is in a subsequent
taxonomy.

This new parameter allows developers to limit queried terms to terminal nodes -
ie, those without any descendants.
As part of the improvement, some internal logic in `get_terms()` has been
consolidated. Parameters that resolve to a NOT IN clause containing term IDs
('exclude', 'exclude_tree', and 'childless') are now parsed into a single
"exclusions" array before the SQL clause is generated.

with duplicate slugs, as long as the terms are in different taxonomies.

that term updates fail when the term being updated shares a slug with an older
term, regardless of that older term's taxonomy.

The new cache group scheme causes term invalidation to be overly broad, so
that busting the cache for one term will bust the cache for all terms in the
taxonomy. We'll have another go at more focused use of the 'last_changed'
