8656a65e1e Coding Standards: Fix and whitelist variable names.
From the `WordPress.NamingConventions.ValidVariableName` sniff, this commit fixes/whitelists all `NotSnakeCaseMemberVar`, `MemberNotSnakeCase`, and `StringNotSnakeCase` violations. It also fixes a handful of the `NotSnakeCase` violations.

a71d208785 General: Fix problematic string to array parsing.
WordPress has historically often used code like `preg_split( '/[\s,]+/', $var )` to parse a string of comma-separated values into an array. However, this approach was causing an empty string to not be parsed into an empty array as expected, but rather into an array with the empty string as its sole element.

This was among other areas causing problems in the REST API where passing an empty request parameter could cause that request to fail because, instead of it being ignored, that parameter would be compared against the valid values for it, which typically do not include an empty string.

0860bb2771 Docs: Remove @access notations from method DocBlocks in wp-includes/* classes.
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.

82911b1756 Cache API: introduce wp_cache_get_last_changed to improve DRY
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.

Since `wp-includes/cache.php` isn't guaranteed to be loaded, this new function is in `wp-includes/functions.php`

3a4169d7ab Comments: Don't do direct SQL query when fetching decendants.
The SQL query was built using the clauses compiled when querying for
top-level comments. But in cases where the top-level comment query
results are already in the cache, the SQL clauses are not built, and
so are unavailable for `fill_descendants()`. Instead, we call
`get_comments()`, using modified versions of the parameters passed
to the main `WP_Comment_Query` class.

e202610ac8 Comments: Improve caching for hierarchical queries.
Hierarchical comment queries work by first fetching the IDs of top-level
comments, and then filling the descendant tree one level at a time based on the
top-level results. When top-level comment IDs are found in the cache,
`WP_Comment_Query` does not generate the SQL used to fetch these comments. In
this case, the `fill_descendants()` query does not have enough information
to fill children. As a result, descendant comments were failing to be filled
in cases where the top-level comments were found in the cache.

This was a minor bug previously, because comment caches were not maintained
between pageloads. Since comment caches are now persistent [37613], the problem
becomes evident anywhere that a persistent object cache is in use.

The solution is to cache parent-child relationships, so that when top-level
comments are found in the cache, descendant comments should be found there as
well.

c5ab953773 Allow comment query results to be limited to comments with comment_post_ID = 0.
Previously, this was not possible due to an overly broad `empty()` check.

Passing `null`, `false`, or `''` to 'post_id', or omitting 'post_id'
altogether, will continue to return comments regardless of `comment_post_ID`,
as before. Passing `0` or `'0'` will limit results to comments with no
associated post.

4c91776f3b Respect all post-related filters in WP_Comment_Query.
The refactor of `WP_Comment_Query`'s SQL generation in [34542] introduced a bug
that caused only the last post-related filter to be respected in comment
queries. In other words, if querying for comments using params
`post_status=draft&post_author=3`, only the last-processed of these params
would be respected. The current changeset fixes the logic so that these clauses
don't overwrite each other.

98fb5f0bdb Use the post-filter WHERE clause when querying for comment descendants.
The descendant query in `WP_Comment_Query::fill_descendants()` uses the clauses
of the main `get_comment_ids()` query as a basis, discarding the `parent`,
`parent__in`, and `parent__not_in` clauses. As implemented in WP 4.4 [34546],
the WHERE clause was assembled in such a way that any modifications applied
using the `comments_clauses` filter were not inherited by `fill_descendants()`.
This resulted in descendant queries that did not always properly filter
results, and sometimes contained syntax errors.

The current changeset fixes the problem by using the post-filter WHERE clause
as the basis for the `fill_descendants()` query. This change requires a new
approach for eliminating the unneeded parent-related clauses: instead of
eliminating values in an associative array, we must use regular expressions.
