Introduce WP_Theme, wp_get_themes(), and wp_get_theme() to replace get_themes(), get_theme(), get_theme_data(), current_theme_info(), and others. * Getters and Helpers: Introduces a series of methods to allow for easy generation of headers for display, and other theme metadata, including page templates. * Screenshots: Handles support for multiple screenshots. (see # Additional screenshots must be PNG and start with screenshot-2.png, and be sequential to be counted. see #19816. * Error Handling: Broken themes have a WP_Error object attached to them. * Caching: Introduces a wp_cache_themes_persistently filter (also in [20020]) to enable persistent caching of all filesystem and sanitization operations normally handled by WP_Theme (and formerly get_file_data() and get_themes()). Themes are cached individually and across five different cache keys for different data pieces. * Compatibility: A WP_Theme object is backwards compatible with a theme's array formerly returned by get_themes() and get_theme(), and an stdClass object formerly returned by current_theme_info(). * i18n/L10n: Theme headers are now localizable with proper Text Domain and Domain Path headers, like plugins. (Language packs may remove the requirement for headers.) For page templates, see #6007 (not fixed yet, but will be easy now). For headers, fixes #15858. * PHP and CSS files: New methods that fetch a list of theme files (for the theme editor) only on demand, rather than only loading them into memory. fixes #11214.

Use `wp_installing()` instead of `WP_INSTALLING` constant. The `WP_INSTALLING` constant is a flag that WordPress sets in a number of places, telling the system that options should be fetched directly from the database instead of from the cache, that WP should not ping wordpress.org for updates, that the normal "not installed" checks should be bypassed, and so on. A constant is generally necessary for this purpose, because the flag is typically set before the WP bootstrap, meaning that WP functions are not yet available. However, it is possible - notably, during `wpmu_create_blog()` - for the "installing" flag to be set after WP has already loaded. In these cases, `WP_INSTALLING` would be set for the remainder of the process, since there's no way to change a constant once it's defined. This, in turn, polluted later function calls that ought to have been outside the scope of site creation, particularly the non-caching of option data. The problem was particularly evident in the case of the automated tests, where `WP_INSTALLING` was set the first time a site was created, and remained set for the rest of the suite. The new `wp_installing()` function allows developers to fetch the current installation status (when called without any arguments) or to set the installation status (when called with a boolean `true` or `false`). Use of the `WP_INSTALLING` constant is still supported; `wp_installing()` will default to `true` if the constant is defined during the bootstrap. Props boonebgorges, jeremyfelt. See #31130.
