When querying for terms in hierarchical categories using `hide_empty=true`,
results have historically included parent terms which are themselves
unattached to any objects (are "empty") but which have non-empty descendent
terms. Because this process involves walking the descendant tree, we avoid it
when we detect that the queried taxonomies are not hierarchical. (This
behavior was introduced in [5525].)
When the `taxonomy` parameter of `get_terms()` was made optional - see #35495,
[36614] - it affected the mechanism for avoiding unneccessary tree walks,
since there may not be any explicitly declared taxonomies to run through
`is_taxonomy_hierarchical()`. As a result, term queries excluding `taxonomy`
did not check descendants, and empty parents with non-empty children were not
included in `hide_empty` results.
We correct the behavior by crawling term descendants when the `taxonomy`
argument is absent, which means that we're querying for terms in all taxonomies.

WPCS 1.0.0 includes a bunch of new auto-fixers, which drops the number of coding standards issues across WordPress significantly. Prior to running the auto-fixers, there were 15,312 issues detected. With this commit, we now drop to 4,769 issues.
This change includes three notable additions:
- Multiline function calls must now put each parameter on a new line.
- Auto-formatting files is now part of the `grunt precommit` script.
- Auto-fixable coding standards issues will now cause Travis failures.

When a term query using `fields=all_with_object_id` hits the cache, the

Generally, duplicate terms returned by a term query are eliminated in PHP,
after the database query takes place. This technique doesn't work properly
when the query parameters specify the `number` of results, since the results
of a `SELECT ... LIMIT x...` query may be deduplicated to a count less than
`x`. In these cases, we force the original query to be `DISTINCT`.

Prior to about 2013, many class methods lacked even access modifiers which made the `@access` notations that much more useful. Now that we've gotten to a point where the codebase is more mature from a maintenance perspective and we can finally remove these notations. Notable exceptions to this change include standalone functions notated as private as well as some classes still considered to represent "private" APIs.

Prior to [38677], `get_term_by()` would always return false if
an empty string were passed as the queried 'name' or 'slug'. The
refactor to use `get_terms()` broke this behavior; inappropriately
imprecise `empty()` checks caused the 'name' or 'slug' clause to be
discarded altogether when fetching terms, resulting in an incorrect
term being returned from the function.
We fix the regression by special-casing truly empty values passed
to `get_term_by()`, and ensuring that `WP_Term_Query` is properly
able to handle `0` and `'0'` term queries.

One thing fairly common to the cache groups is a block of code to look to see when the cache was last changed, and if there isn't one, to set it for the current microtime(). It appears in 8 different places in core. This adds a new helper `wp_cache_get_last_changed` to DRY things up a bit.

The new 'object_ids' parameter for `WP_Term_Query` allows queries for
terms that "belong to" a given object. This change makes it possible
to use `WP_Term_Query` inside of `wp_get_object_terms()`, rather than
assembling a SQL query.
The refactor has a couple of benefits:
* Less redundancy.
* Better consistency in accepted arguments between the term query functions. See #31105.
* Less redundancy.
* Object term queries are now cached. The `get_object_term_cache()` cache remains, and will be a somewhat less fragile secondary cache in front of the query cache (which is subject to frequent invalidation).
* Less redundancy.
A small breaking change: Previously, if a non-hierarchical taxonomy had
terms that had a non-zero 'parent' (perhaps because of a direct SQL
query), `wp_get_object_terms()` would respect the 'parent' argument.
This is in contrast to `WP_Term_Query` and `get_terms()`, which have
always rejected 'parent' queries for non-hierarchical taxonomies. For
consistency, the behavior of `get_terms()` is being applied across the
board: passing 'parent' for a non-hierarchical taxonomy will result in
an empty result set (since the cached taxonomy hierarchy will be empty).

Prior to the introduction of `WP_Term_Query`, the 'orderby' clause
passed to the 'terms_clauses' filter was prefixed by `ORDER BY`. After
`WP_Term_Query`, this was not the case; `ORDER BY` was added after the
filter. As such, plugins filtering 'terms_clauses' and returning an
'orderby' clause beginning with `ORDER BY` resulted in invalid syntax
when `WP_Term_Query` prepended a second `ORDER BY` keyword to
the clause.
This changeset rearranges the way the 'orderby' clause is built so that
it will be passed to 'terms_clauses' in the previous format.

In order to allow meta-related values of `orderby` to be handled properly,
the term query's `meta_query` object must run its `get_sql()` method before
`orderby` parsing.
Fixing this bug required addressing another bug in `WP_Meta_Query`, which
caused the table alias index not to be reset when calling `get_sql()`
multiple times on the same object.
