* Don't lower memory limit if the current limit is greater than `WP_MAX_MEMORY_LIMIT`.
* Set `WP_MEMORY_LIMIT` and `WP_MAX_MEMORY_LIMIT` to current limit if the `memory_limit` setting can't be changed at runtime.
* Use `wp_convert_hr_to_bytes()` when parsing the value of the `memory_limit` setting because it can be a shorthand or an integer value.
* Introduce `wp_raise_memory_limit( $context )` to raise the PHP memory limit for memory intensive processes. This DRYs up some logic and includes the existing `admin_memory_limit` and `image_memory_limit` filters. The function can also be used for custom contexts, the `{$context}_memory_limit` filter allows to customize the limit.
* Introduce `wp_is_ini_value_changeable( $setting )` to determine whether a PHP ini value is changeable at runtime.
* Remove a `function_exists( 'memory_get_usage' )` check. Since PHP 5.2.1 support for memory limit is always enabled.

`wp_convert_hr_to_bytes()` was previously defined in wp-includes/media.php because it's only used by `wp_max_upload_size()` in the same file.
Moving this function to load.php allows us to improve core's memory limit handling.

Previously, if a user was added with the checkbox for no confirmation selected and an error was then encountered in `wpmu_activate_signup()`, a fatal error would trigger because `$new_user` was a `WP_Error` object rather than a user.

When comment IDs are fetched from the cache rather than the database,
the subsequent `SELECT FOUND_ROWS()` query will not return the correct value.
To avoid unnecessary queries, we cache the results of the `found_comments`

The array-compatibility object we started returning in r37428 unfortunately isn't enough like an array. In particular, `is_array()` checks fail, despite the object implementing ArrayAccess. Mea culpa.
This moves the WP_HTTP_Response object to a new http_response key in the array, and changes the value back to an actual array.

When enabled, the switch would override the theme's pseudo-plural `'% Comments'` string with a correct form of `_n( '%s Comment', '%s Comments', $number )`.
Historically, `comments_popup_link()` and `get_comments_number_text()` did not support plural forms and used a pseudo-plural style instead, so some locales were forced to come up with workarounds to display the number of comments in their language correctly.
This change should make those functions more i18n-friendly.

In `wp_calculate_image_srcset()` we get an array of image sizes
associated with an attachment and then add the original image's
information to the array before processing the `srcset`. In doing
so, we set the original data to a `$image_sizes['full']` key, which
could stomp on any custom image sizes using `full` as a size name.
This avoid the issues by adding the original data without a named
key, which is never referenced anyway.

`wp_plugin_update_rows()` and `wp_theme_update_rows()` are using the site transients `update_plugins` and `update_themes` which are set by `wp_update_plugins()` and `wp_update_themes()`.

`Pragma` is supposed to be a request header, but we've been including it in responses since the beginning of time.
This is a relic dating all the way back to b2, probably originally added because Internet Explorer version 5 and earlier didn't understand the `Cache-Control` header in responses, but they did (incorrectly) obey the `Pragma` header.
Internet Explorer 6 and 7 will obey the `Pragma` response header only if no other cache-related response headers are present (in our case, they are always present), and all other browsers ignore the `Pragma` response header.

`register_meta()` has been altered to accept an array of arguments as the third parameter in order to support its usage beyond XML-RPC, notably in the REST API and other projects that may build on top of meta, such as a potential Fields API. Arguments are whitelisted to reserve the right for core to add more later.
New functions added to complement this expansion are:
* `registered_meta_key_exists()`
* `unregister_meta_key()`
* `get_registered_meta_keys()`
* `get_registered_metadata()`
* A "private" function for the aforementioned whitelisting.
There still need to be lots of tests written for previous and new behaviors, and many things are subject to change. Maybe things will explode. #yolo

In [37888], the comment text was initially updated, however an opportunity to make the text less trivializing of actions that users will take was missed. To quote Helen Hou-Sandi: "It's important not to trivialize actions that are perfectly reasonable for a user to find tricky (where to go to log in is not exactly intuitive, even with the rewrites we have now)."
The text of the comment now reads:

Resource hints allow browsers to prefetch specific pages or render them in the background to perform DNS lookups or to begin the connection handshake (DNS, TCP, TLS) in the background.
By default, `wp_resource_hints()` prints hints for "s.w.org" (the WordPress.org CDN) and for all scripts and styles which are enqueued from external hosts.

In the past, `get_blog_details()` has been used to retrieve the `home`, `siteurl`, `blogname`, and `post_count` options for a site. By lazy loading properties in a `WP_Site` object, we can avoid having to use `get_blog_details()` and instead provide the properties as needed.
This introduces the global `site-details` cache group in which standard objects representing the site are stored. This will one day be a replacement for the `blog-details` cache group that is currently used in `get_blog_details()`.
This relies on the `ms_loaded` action introduced in [37916] as properties are not available via `get_option()` until multisite has been fully loaded.

This adds three new functions for getting/displaying attachment captions:
* `wp_get_attachment_caption` - Retrieves a caption for a specific attachment.
* `get_the_post_thumbnail_caption()` - Returns the post thumbnail caption.
* `the_post_thumbnail_caption()` - Displays the post thumbnail caption.
These are helpful for displaying a caption associated with an image directly
in a template, rather than using the caption shortcode.
This also introduces two new filters:
* `wp_get_attachment_caption` - Filters the value of `wp_get_attachment_caption()`.
* `the_post_thumbnail_caption` - Filters the display of the post thumbnail caption.
`the_post_thumbnail_caption()` is automatically filtered by `wptexturize()`,
`convert_smilies()`, and `convert_chars()` in `wp-includes/default-filters.php`.
