Editor-expand: reset the editor height after the window is resized. Fixes #29952 for trunk.

Introduce support for nested queries in WP_Meta_Query.

Previously, meta 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.

Adds unit tests for the new nesting syntax. Modifies a few existing unit tests
that were overly specific for the old SQL syntax. Backward compatibility with
existing syntax is fully maintained.

Use assertEqualSets() for a few taxonomy-related tests.

assertEquals() was causing problems in environments where the tests take more
than one second to run, thereby causing results to be returned in the incorrect
order.

Use only LEFT JOINs when a meta_query contains a NOT EXISTS clause.

Mixing LEFT and INNER JOIN in these cases results in posts with no metadata
being improperly excluded from results.

Introduce support for nested queries in WP_Tax_Query.

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.

Props boonebgorges.
Fixes #29718. See #29738.

Fix theme support unit test added in [27220].

The test assumed that the active theme either had no menu locations, or a subset of 'primary' and 'secondary'. see #26900.

Support 'EXISTS' and 'NOT EXISTS' in `WP_Tax_Query`.

These new values for the 'operator' parameter make it possible to filter items
that have no term from a given taxonomy, or any term from a given taxonomy.

Support nested tax query syntax in redirect_canonical().

The proper place to look for a list of queried terms is in the flat
queried_terms array, not in tax_query->queries.

Avoid redundant table joins in WP_Tax_Query.

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.

Introduces WP_Tax_Query::sanitize_relation() to reduce some repeated code.

Adds unit tests to verify the JOIN consolidation, and integration tests for
cases where JOINS are being combined.
