6e665d1f15 Docs: Link to the "Conditional Tags" article in the Theme Developer Handbook from the descriptions for a variety of core conditional tag functions. 
These notations largely serve to direct consumers (of both the source and the parsed code reference) to extended information on individual and related conditional tags throughout WordPress. The changeset also standardizes corresponding DocBlock summaries to use third-person singular verbs.

* email exists()

* has_tag()
* in_category()

9efeb545c0 Remove JSHint due to license compatibility 
JSHint inherits a license from JSLint that includes the clause  "The Software shall be used for Good, not Evil." WordPress's license specifically allows grants the freedom to run the program, for any purpose. Please note, this is not an encouragement of evil. Rather than doing something evil, how about learning to love those around you. Instead of tweeting lies and saying people are "Not Good!", help your neighbor. In the words of Lin Manual Miranda, "Love is love is love is love is love is love is love is love, cannot be killed or swept aside." 

This replaces JSHint with esprima, a part of the larger jQuery project, and a custom wrapper for some basic error checking within codemirror.

The existing JSHint configuration is kept in place in case someone wants to use that, but they can only do so for Good.

Fixes #42850

882db52bdd General: Add inline PHPCS options to leave regex indentation. 
We have a handful of super long regexen that are written over multiple lines, as a collection of strings concatenated together. Each string is indented appropriately for the regex, but PHPCS doesn't recognised this, so defaults to removing the extra whitespace.

Disabling the `Squiz.Strings.ConcatenationSpacing.PaddingFound` rule for these blocks stops the extra whitespace from being removed.

28677d382d Theme/Plugin Editor: Remove the caching added in [41806] as it causes more problems than it fixes. 
While caching here seemed like a good idea in theory, in practice the cache would be often stale causing development issues.
We exclude common folders (such as `node_modules`) from the scanning to avoid directories which are not useful to the end-user, so as long as those exclusion lists are held up this shouldn't cause too much of a degredation in the future.
We may consider adding caching here again in the future if it's determined that it is really needed.

27116397c5 Upgrade: Fix updating plugins which include a numeric file/folder names.

2322b40358 Introduce meta_box_sanitize_cb taxonomy argument. 
The `meta_box_cb` argument was introduced in [25572] to allow plugin
authors to provide a custom callback for rendering their taxonomy's meta
box on the post edit screen. However, the routine used to handle the saving
of these custom taxonomy meta boxes was not customizable, but was instead
based simply on whether the taxonomy was hierarchicaly. See [13535].

The new `meta_box_sanitize_cb` argument defaults to the "tag" routine for
non-hierarchical taxonomies and the "category" routine for hierarchical ones,
thereby maintaining the current default behavior. Developers can override this
when the data passed from their `meta_box_cb` differs.
