This improves performance for sites with persistent cache backend having a lot of pages requested via the `get_pages() function, by taking advantage of `wp_cache_get_multiple()` instead of fetching each individual page from the backend cache server one by one.
It also matches the behaviour of `get_pages()` when the pages are retrieved from the database.

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.

Object type-specific actions that should happen before or after modification of metadata have so far been part of the respective wrapper functions. By using action and filter hooks, this changeset ensures they are always executed, even when calling the lower-level Meta API functions directly, which the REST API does as a prime example.
Merges [43729] to trunk.

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.
Fixes#44600.

Introduce an `object_subtype` argument to the args array for `register_meta()` which can be used to limit meta registration to a single subtype (e.g. a custom post type or taxonomy, vs all posts or taxonomies).
Introduce `register_post_meta()` and `register_term_meta()` wrapper methods for `register_meta` to provide a convenient interface for the common case of registering meta for a specific taxonomy or post type. These methods work the way plugin developers have often expected `register_meta` to function, and should be used in place of direct `register_meta` where possible.

`wp_check_for_changed_dates()`, `_find_post_by_old_slug(), `_find_post_by_old_date()`, and the `old_slug_redirect_post_id` filter were intended to land in 4.9.2, but didn't quite make it. Instead, they'll be landing in 4.9.3.
