`WP_List_Table` is essentially an `abstract` class. Some of its methods throw `die()` warnings if they aren't overridden in a child class.
These noop methods wouldn't be `abstract`, because they are not required in subclasses. However, `WP_List_Table` can call these methods in its own method, `->single_row_columns()`, whether a subclass defined them or not.

Taxonomy hierarchy loops should not occur naturally, but when they do, the
logic of `_pad_term_counts()` could result in infinite loops, leading to
timeouts. We avoid this by breaking when a loop is detected.

Since 4.1 [29780], the default value of the 'add_args' argument in
`paginate_links()` has been determined by parsing the current URL. This change
had the side effect of overriding custom values of 'format' that changed the
pagination query var, with the result that plugins using `paginate_links()`
with a custom format generated the incorrect links unless explicitly
declaring 'add_args=false' to prevent the default values from overriding. We
fix this behavior by parsing URL query vars into the 'add_args' array only
after the explicit function params have been parsed, and by skipping the
current page's pagination query var when doing this parsing (to avoid the
override).
Props obenland.

In PHP 5.3.0, `is_a()` is no longer deprecated, and will therefore no longer throw `E_STRICT` warnings.
To avoid warnings in PHP < 5.3.0, convert all `is_a()` calls to `$var instanceof WP_Class` calls.
`instanceof` does not throw any error if the variable being tested is not an object, it simply returns `false`.

Note that this does not fix issues related to comment quick edit. Internal linking also continues to use the `.alternate` class for now. IE8 and below gracefully degrade by not having zebra striping.
There is some hoop jumping with adding an extra table row to maintain zebra striping during quick edit. Documenting that here for future reference; it is also in the inline documentation.

Introduced in [29925], `validate_date_values()` throws `_doing_it_wrong()`
notices when values passed as part of a `WP_Date_Query` do not reflect actual
dates. However, the validation did not account properly for the case where an
array of multiple values is passed, as when doing IN or BETWEEN queries.

Up to this point, various core elements' DocBlocks incorrectly included an `@internal` tag as a means for skipping the parsing process. When paired with a description (inline or otherwise), `@internal` is a valid tag meant to provide internal-only context, but not necessarily to skip parsing the entire element.

When editing a site, if `home` and `siteurl` are checked to be updated along with a site's domain and path, they should receive the results of any modifications in `update_blog_details()` rather than trusting the POST data.
Previously, it was possible to save a value without a leading slash on the path, causing an invalid URL to be stored.

In multisite, core expects the stored value for a site's path to have leading and trailing slashes. When these slashes are missing, it becomes impossible to visit the site.
This enforces proper `/path/` creation in `update_blog_details()`, most likely used when updating an existing site through `site-info.php`.

[29863] made the corresponding change in `term_exists()`. Failure to change the
default value in `category_exists()` meant that an unspecified value for
`$parent` would limit results to top-level categories.

* Exactly one method was made private in [28516], and is only used internally.
* 2 properties were made private, but they just store variables passed to the constructor.
* Instances of this class are never created in core. `WP_MatchesMapRegex::apply()` is called statically in `WP->parse_request()` and `url_to_postid()`.
The chances that:
1) this class is used as an instance somewhere and
2) the properties that have always been marked `@access private` and begin with `_` were used publicly
...is extremely low.
Remove the magic methods, I should not have added them.
While we're at it, use the PHP5-style `__construct()` instead of the class name.
