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.

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.

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.

The integration tests for using date_query in WP_Query require the creation of
dummy post data, much of which is common between a number of tests. However,
newer tests do not require as much data, so to reduce overhead we create the
data explicitly only when we need it, instead of in the setUp() method.

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.
Adds unit test for the sanitization issue. Modifies existing unit test to
reflect the change in return value for empty term strings.

These unit tests cover the expected vehaviour of certain combinations of URL's, but makes no attempt to test invalid URL structures, as PHP's behavious for invalid URL's is undefined (Some will be treated as paths, others fail, and it varies between PHP 5.4.7+ and <5.4.7).
This change also makes WP_HTTP::parse_url() protected in order to allow unit testing.

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 older versions of PHP:
- parse_url() will fail to parse a url where the scheme break (://) is present in a relative URL's path
- parse_url() will include the hostname of a schemeless URL in the path component
This handles those two types of URL's by correcting the response from parse_url().

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().

When using legacy `meta_key`, `meta_value`, etc. arguments in `WP_Query`,
they're converted into the first clause of a `meta_query`. By using that
clause instead of the original arguments, we make sure that behavior is
consistent between the two available formats.

Previously this would use the generic message corresponding to the response code, which isn't always accurate. Since we're already parsing the headers, we can simply return that directly (This also has the benefit that it's the same code for both Streams and Curl header handling).

Not having the count caused queries with 'fields' values of 'id=>name' and
'id=>slug' to return incorrect results when querying a hierarchical taxonomy
with 'hide_empty=true'.

'hide_empty', and 'hierarchical' arguments.
