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.
