Boone Gorges 3e9c88d75a In `delete_metadata()`, only invalidate cache for affected objects. 
The `$delete_all` flag in `delete_metadata()` triggers cache invalidation for
multiple objects. Previously, invalidation took place for all objects matching
the `$meta_key` parameter, regardless of whether `$meta_value` was also set.
This resulted in overly aggressive invalidation.

Boone Gorges 5dfd6a02a7 Avoid returning duplicate matches when using a meta query in `WP_User_Query`. 
A meta_query containing an `OR` relation can result in the same record matching
multiple clauses, leading to duplicate results. The previous prevention against
duplicates [18178] #17582 became unreliable in 4.1 when `WP_Meta_Query`
introduced support for nested clauses. The current changeset adds a new method
`WP_Meta_Query::has_or_relation()` for checking whether an `OR` relation
appears anywhere in the query, and uses the new method in `WP_User_Query` to
enforce distinct results as necessary.

Boone Gorges 7bde88d02e Modify `meta_query orderby syntax to use array keys as clause "handles". 
The implementation of `meta_query` orderby introduced in [31312] put clause
identifiers into a 'name' parameter of the clause. For greater clarity, this

Boone Gorges ca30c725a0 Improve support for ordering `WP_Query` results by postmeta. 
`WP_Meta_Query` clauses now support a 'name' parameter. When building a
`WP_Query` object, the value of 'orderby' can reference this 'name', so that
it's possible to order by any clause in a meta_query, not just the first one
(as when using 'orderby=meta_value'). This improvement also makes it possible
to order by multiple meta query clauses (or by any other eligible field plus
a meta query clause), using the array syntax for 'orderby' introduced in [29027].

Boone Gorges 9345e9ffa5 Overhaul SQL generating logic in WP_Meta_Query to avoid unnecessary table joins. 
The logic used to generate clause SQL in `WP_Meta_Query` is somewhat arcane,
stemming mostly from an ongoing effort to eliminate costly table joins when
they are not necessary. By systematizing the process of looking for shareable
joins - as was done in `WP_Tax_Query` [29902] - it becomes possible to simplify
the construction of SQL queries in `get_sql_for_clause()`. Moreover, the
simplified logic is actually considerably better at identifying shareable
joins, such that certain uses of `WP_Meta_Query` will see joins reduced by 50%
or more.

Includes integration tests for a representative cross-section of the query
clause combinations that result in shared table aliases.

Scott Taylor 0115ba2f30 When using `meta_query` in a `WP_Query`, passing `NOT EXISTS` or `''` to `compare` should not require `value` to be set. The resulting SQL should then produce the appropriate `OR` clause for existence of non-existence after passing the query to the `$key_only_queries` stack internally. 
Adds unit tests. 

Props chrisguitarguy, for the original patch.
