Make WordPress Core

Message:

Add missing doc blocks to update.php:

  • wp_version_check(), wp_update_plugins(), and wp_update_themes() do not return meaningful responses, and their responses are never handled by core. As such, they shouldn't alternately return void or false. "Returning" in those functions is just "bailing"
  • In the same functions, version.php doesn't need to load if WP_INSTALLING is defined - the function will immediately bail, the values will never be read, and the globals won't be reset. I have unified the approach in all 3 functions.
  • When returning filtered $locale, there is no need to set the variable twice.
  • In _maybe_update_core(), isset() can take multiple values to bail before the call to time(), if necessary. This is a micro-optimization to prevent PHP from hitting the OS unnecessarily.

See #32444.
