`wp_insert_term()` does not allow for terms with the same name to exist
at the same hierarchy level, unless the second term has a unique slug.
When this logic was refactored in [31792] and [34809], a bug was
introduced whereby it was possible to bypass the no-same-named-sibling
check in cases where the first term had a non-auto-generated slug
(ie, where the name was 'Foo' but the slug something other than 'foo',
such that the second term would get the non-matching slug 'foo').
This changeset fixes this issue by ensuring that the duplicate name
check runs both in cases where there's an actual slug clash *and* in
cases where no explicit `slug` has been provided to `wp_insert_term()`.
The result is a more reliable error condition:
`wp_insert_term( 'Foo' ... )` will always fail if there's a sibling
'Foo', regardless of the sibling's slug.

REST API endpoints for your WordPress content. These endpoints provide machine-readable external access to your WordPress site with a clear, standards-driven interface, allowing new and innovative apps for interacting with your site. These endpoints support all of the following:
- Posts: Read and write access to all post data, for all types of post-based data, including pages and media.
- Comments: Read and write access to all comment data. This includes pingbacks and trackbacks.
- Terms: Read and write access to all term data.
- Users: Read and write access to all user data. This includes public access to some data for post authors.
- Meta: Read and write access to metadata for posts, comments, terms, and users, on an opt-in basis from plugins.
- Settings: Read and write access to settings, on an opt-in basis from plugins and core. This enables API management of key site content values that are technically stored in options, such as site title and byline.
Love your REST API, WordPress! The infrastructure says, "Let's do lunch!" but the content API endpoints say, "You're paying!"

Since [37573], `get_object_term_cache()` has expected term IDs to be
stored in the taxonomy relationship cache. The function would then
reach directly into the 'terms' cache to fetch the data corresponding
to a given term, before returning a `WP_Term` object. This caused
problems when, for one reason or another, term data was cached
inconsistently:
* If the 'terms' cache is empty for a given term ID, despite the earlier call to `_prime_term_caches()`, `get_term()` would return an error object.
* If the array of cached term IDs contains an invalid ID, `get_term()` would return an error object.
We avoid these errors by no longer touching the 'terms' cache directly,
but running term IDs through `get_term()` and allowing that function to
reference the cache (and database, as needed). If `get_term()` returns
an error object for any of the cached term IDs, `get_object_term_cache()`
will return that error object alone. This change ensures that upstream
functions, like `get_the_terms()`, return `WP_Error` objects in a
predictable fashion.

This introduces the singular `edit_term`, `delete_term`, and `assign_term` meta capabilities for terms, and switches the base capability name for tags from `manage_categories` to `manage_post_tags` and the corresponding `edit_post_tags`, `delete_post_tags`, and `assign_post_tags`.
All of these capabilities ultimately map to `manage_categories` so by default there is no change in the behaviour of the capabilities for categories, tags, or custom taxonomies. The `map_meta_cap` filter and the `capabilities` argument when registering a taxonomy now allow for control over editing, deleting, and assigning individual terms, as well as a separation of capabilities for tags from those of categories.

The new 'object_ids' parameter for `WP_Term_Query` allows queries for
terms that "belong to" a given object. This change makes it possible
to use `WP_Term_Query` inside of `wp_get_object_terms()`, rather than
assembling a SQL query.
The refactor has a couple of benefits:
* Less redundancy.
* Better consistency in accepted arguments between the term query functions. See #31105.
* Less redundancy.
* Object term queries are now cached. The `get_object_term_cache()` cache remains, and will be a somewhat less fragile secondary cache in front of the query cache (which is subject to frequent invalidation).
* Less redundancy.
A small breaking change: Previously, if a non-hierarchical taxonomy had
terms that had a non-zero 'parent' (perhaps because of a direct SQL
query), `wp_get_object_terms()` would respect the 'parent' argument.
This is in contrast to `WP_Term_Query` and `get_terms()`, which have
always rejected 'parent' queries for non-hierarchical taxonomies. For
consistency, the behavior of `get_terms()` is being applied across the
board: passing 'parent' for a non-hierarchical taxonomy will result in
an empty result set (since the cached taxonomy hierarchy will be empty).

`get_terms()` has historically required that a taxonomy be specified when
querying terms. This requirement is related to the fact that terms could
formerly be shared between taxonomies, making `$taxonomies` critical for
disambiguation. Since terms can no longer be shared as of 4.4, it'
s desirable to be able to query for terms regardless of what taxonomy they're in.
Because it's now optional to pass taxonomies, it's no longer necessary to have
`$taxonomies` as the first (and required) parameter for `get_terms()`. The new
function signature is `get_terms( $args )`, where 'taxonomy' can (optionally) be
passed as part of the `$args` array. This syntax is more consistent with
functions like `get_users()` and `get_posts()`.
We've maintained backward compatibility by always giving precedence to the old
argument format. If a second parameter is detected, or if it's detected that
the first parameter is a list of taxonomy names rather than an `$args` array,
`get_terms()` will parse the function arguments in the legacy fashion.

This brings order-by-meta support for terms in line with post, comment, and
user queries.
As a byproduct of these improvements, `$meta_key` and `$meta_value` parameters
have been introduced to `get_terms()`. They interact with `$meta_query` in the

[35333] implemented `public=false` for taxonomies. The implementation prevented
non-public taxonomies from having their archives accessed via query_var during
a normal request. But it didn't prevent non-public taxonomies from registering
their query vars in the `$wp_taxonomies` global. The latter implementation
details causes problems specifically when a taxonomy is registered with
`query_var=true`; for public taxonomies, `register_taxonomy()` translates this
into a query_var equivalent to the taxonomy name, but in the case of non-public
taxonomies, the query_var was set to the boolean itself. The boolean then
causes problems when using non-strict comparison to filter taxonomy objects by
query_var, as when using `get_taxonomies()`.

non-public taxonomies to `false`.

`get_term()` now returns a `WP_Term` object, instead of a `stdClass` object.
Cache support and sanitization filters for individual terms are now more
centralized. For example, `get_term_by()` is able to cast results of its query
to a `WP_Term` object by passing it through `get_term()`.
The `$taxonomy` parameter for `get_term()` is now optional, as terms ought to
be unique to a taxonomy (ie, shared terms no longer exist). In cases where
`get_term()` detects that the term matching the specified term_id is from the
wrong taxonomy, it checks to see if you've requested a shared term, and if so,
it splits the term. This is used only for fallback purposes.
The elimination of shared terms allows the caching strategy for terms to be
simplified. Individual terms are now cached in a single 'terms' bucket.
