The `$orderby` parameter of `get_terms()` now accepts the following values,
related to term meta:
* 'meta_value'
* 'meta_value_num'
* the value of the `$meta_key` parameter
* any key from the `$meta_query` array
This brings order-by-meta support for terms in line with post, comment, and
user queries.
As a byproduct of these improvements, `$meta_key` and `$meta_value` parameters
have been introduced to `get_terms()`. They interact with `$meta_query` in the
same way as in `WP_Query` and other query classes.

running it through `sanitize_term_field( 'name' )` before performing the SQL
query. An unintentional side effect of this change was that the string is
double-escaped: once by `wp_filter_kses()`, and once by `esc_sql()`. The
double-escaping was causing 'name' queries to fail when the param contained

[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()`.
This changeset addresses the issue by forcing the query_var property of
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.

[32814] introduced a routine to split shared terms, which was run during the

that plugins were not able to hook into the 'split_shared_term' action during
the bulk split. We work around this limitation by moving the term splitting
routine to a separate process, triggered by a wp-cron hook.

`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`

the current changeset restores the original behavior.
A number of unit tests are added and refactored in support of these changes.

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.

A "shared" term occurs when two entries in the `wp_term_taxonomy` table share a
single `term_id`, and thereby correspond to the same row in `wp_terms`. This
changeset stops the practice of creating shared terms: each new row in
`wp_term_taxonomy` will receive its own row in `wp_terms`. The new strategy
for term creation depends on whether the installation's database schema is up
to date for 4.1:
* If so, terms are allowed to be created with the same slug as an existing term, as long as they are in different taxonomies and do not share a parent. Thus, a new tag with the slug 'wordpress' can exist alongside a category with the slug 'wordpress'.
* If not, new terms will be forced to have unique slugs. Thus, on an installation containing a category with the slug 'wordpress', a new tag 'WordPress' will get the slug 'wordpress-2'.

In case of edge cases where a duplicate term might exist in a replicated
database for a split second, these explicit query clauses ensure that
`term_exists()` will always recognize the oldest matched term as the
canonical one. See [30238] for background.

In [30056], the UNIQUE index was removed from the 'slug' column of `wp_terms`.
While we have numerous checks in place to avoid the creation of unwanted
duplicate term+term_taxonomy pairs, it's possible that in certain edge cases -
such as during the lag caused by database replication, or a race condition
involving near-simultaneous creation of more than one term - we'll end up
unwittingly inserting two identical rows.
The current changeset minimizes this risk by introducing a failsafe mechanism
into `wp_insert_term()`. After a term and term_taxonomy are INSERTed, we check
to see whether the term just created is a duplicate of an existing term; if so,
we delete the new one and keep the old one. This prevents problems caused by
replication lag, because SELECT queries that take place after an INSERT will
hit the master database; it mitigates race conditions by enforcing that the
term that was created first (ie, the one with the lowest `term_id`) is
always the "canonical" one.

* In `the_taxonomies()`, only document those arguments that are specific to the function. Arguments shared with `get_the_taxonomies()` should be documented in the later function's docblock.
* Add $args hash documentation to `get_the_taxonomies()`.
* Remove the redundant default argument definition in `the_taxonomies()`.

The previous behavior resulted in descendant terms being improperly excluded
from the results when passing a 'parent', even when 'hierarchical' had been
set to true.
The patch also adds unit tests that demonstrate the various interactions
between the 'child_of', 'parent', and 'hierarchical' parameters of `get_terms()`.

Per our inline documentation standards, no further use of the `@uses` tag is recommended as used and used-by relationships can be derived through other means. This removes most uses of the tag in core documentation, with remaining tags to be converted to `@global` or `@see` as they apply.

* When caching a term, also make cache entries for slug and name via `slug:{$term_id}` and `name:{$term_id}` keys in the `$taxonomy:$last_changed` bucket that reference the term_id
* In `clean_term_cache()` and `update_term_cache()`, respect `$_wp_suspend_cache_invalidation`

IN clauses that are connected by OR require only a single table join. To avoid
extraneous joins, keep track of generated table aliases, and let sibling
clauses piggy-back on those aliases when possible.

Adds unit tests to verify the JOIN consolidation, and integration tests for

Previously, tax query arguments could be joined by a single AND or OR relation.
Now, these queries can be arbitrarily nested, allowing clauses to be linked
together with multiple relations.
In a few places, WP_Query runs through a list of clauses in a tax_query in order
to set certain query vars for backward compatibility. The necessary changes have
been made to WP_Query to support this feature with the new complex structure of
tax_query. Unit tests are included for these backward compatibility fixes.
Unit tests for the new nesting syntax are included.

This change brings return values for failures of this sort in line with other
failed lookups in term_exists(): a null value is now returned in all cases
where the queried term is not found.

Using get_term_by() rather than direct SQL queries to fetch the alias term
fixes a number of issues:
* Object cache for aliased term is properly cleared after update.
* If the aliased term is in the object cache, it's served from there, saving a database query.
* Duplicate 'edit_terms' and 'edited_terms' hooks can be removed.
* Fix a PHP notice when the 'alias_of' term is not found.
* Prevent the incorrect creation of a new term group for the primary term when the 'alias_of' term is not found.
Adds unit tests for 'alias_of' functionality in both functions.

In certain edge cases, such as during the automated test suite,
create_initial_taxonomies() can be called in a situation where a non-default
permastruct setting has been saved outside of wp-admin. This causes the
'hierarchical' setting for the post_tag taxonomy to remain unset, leading to
PHP notices in get_term_link().
