Previously, changing the post thumbnail of a published post in the edit screen
would immediately apply the change, rather than waiting for the post to be
saved before applying the update. This could lead to someone unintentionally
editing the post thumbnail on a published post, and made it impossible to
preview changes to post thumbnails on published posts before saving the change.
This introduces a new Ajax handler, `wp_ajax_get_post_thumbnail_html()` to
retrieve the HTML for the post thumbnail meta box without updating the post
meta value for `_thumbnail_id`. It also allows post thumbnail changes to be
previewed by passing the `_thumbnail_id` as a query variable to the preview
screen and adding a new filter, `_wp_preview_post_thumbnail_filter()`, which
gets applied to `get_post_metadata` during the post preview process.

When `IMAGE_EDIT_OVERWRITE` is set to true, edited image files are
supposed to be deleted when an image is restored to the original.
However, when an image was edited more than once, and then restored,
files created during previous edits were left behind.
Fixes this behavior by updating `wp_save_image()` to clean up
leftover images after each edit when `IMAGE_EDIT_OVERWRITE` is true.

[36874] changed the `get_term()` call so that no `$taxonomy` parameter
was passed, as 4.4 made the parameter optional. This change made it
impossible to access a shared term that has not yet been splitr, since
passing an ambiguous `$term_id` to `get_term()` results in an error.
Restoring the `$taxonomy` parameter fixes the regression.

* 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.

`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.

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.

like a toggle to expand the uploader panel and should be a `button` element with

- keeps the themes list visible when the uploader is open
- displays a notice when JavaScript is off
- adds some `hide-if-no-js` CSS classes

When Open Sans was in use, the `300`, `400`, and `600` weights were loaded. `400` is the equivalent of `normal`; however, `bold` is equivalent to `700`, not `600`. With the move to system fonts, we need to be specific rather than relying on the lack of a `700` weight. Not all system fonts include a `600` weight; in those instances, they will use the `bold`/`700` weight.
