Felix Arntz 92c3c46abe Bootstrap/Load: Revert fatal error recovery mechanism from 5.1 to polish for 5.2. 
Due to the high number of follow-up tickets and associated security concerns, it was decided to reschedule the fatal error recovery feature for WordPress 5.2, in order to address these issues properly. The feature will continue to be developed, with iterations being merged into trunk early in the 5.2 release cycle.

Fixes #46141. See #44458, #45932, #45940, #46038, #46047, #46068.

Built from https://develop.svn.wordpress.org/trunk@44717

/**
* Retrieves theme installer pages from the WordPress.org Themes API.
*
* It is possible for a theme to override the Themes API result with three
* filters. Assume this is for themes, which can extend on the Theme Info to
* offer more choices. This is very powerful and must be used with care, when
* overriding the filters.
*
* The first filter, {@see 'themes_api_args'}, is for the args and gives the action
* as the second parameter. The hook for {@see 'themes_api_args'} must ensure that
* an object is returned.
*
* The second filter, {@see 'themes_api'}, allows a plugin to override the WordPress.org
* Theme API entirely. If `$action` is 'query_themes', 'theme_information', or 'feature_list',
* an object MUST be passed. If `$action` is 'hot_tags', an array should be passed.
*
* Finally, the third filter, {@see 'themes_api_result'}, makes it possible to filter the
* response object or array, depending on the `$action` type.
*
* Supported arguments per action:
*
* | Argument Name | 'query_themes' | 'theme_information' | 'hot_tags' | 'feature_list' |
* | -------------------| :------------: | :-----------------: | :--------: | :--------------: |
* | `$slug` | No | Yes | No | No |
* | `$per_page` | Yes | No | No | No |
* | `$page` | Yes | No | No | No |
* | `$number` | No | No | Yes | No |
* | `$search` | Yes | No | No | No |
* | `$tag` | Yes | No | No | No |
* | `$author` | Yes | No | No | No |
* | `$user` | Yes | No | No | No |
* | `$browse` | Yes | No | No | No |
* | `$locale` | Yes | Yes | No | No |
* | `$fields` | Yes | Yes | No | No |
*
* @since 2.8.0

* 'hot_tags' or 'feature_list'.
* @param array|object $args {
* Optional. Array or object of arguments to serialize for the Themes API.
*
* @type string $slug The theme slug. Default empty.

* @type array $fields {

* @type bool $screenshots Whether to return the screenshots. Default false.
* @type int $screenshot_count Number of screenshots to return. Default 1.
* @type bool $screenshot_url Whether to return the URL of the first screenshot. Default false.
* @type bool $photon_screenshots Whether to return the screenshots via Photon. Default false.
* @type bool $template Whether to return the slug of the parent theme. Default false.
* @type bool $parent Whether to return the slug, name and homepage of the parent theme. Default false.
* @type bool $versions Whether to return the list of all available versions. Default false.
* @type bool $theme_url Whether to return theme's URL. Default false.
* @type bool $extended_author Whether to return nicename or nicename and display name. Default false.
