With the introduction of user-specific languages in [38705] it's necessary to be able to switch translations on the fly. For example emails should be sent in the language of the recipient and not the one of the current user.
This introduces a new `WP_Locale_Switcher` class which is used for switching locales and translations. It holds the stack of locales whenever `switch_to_locale( $locale )` is called. With `restore_previous_locale()` you can restore the previous locale. `restore_current_locale()` empties the stack and sets the locale back to the initial value.
`switch_to_locale()` is added to most of core's email functions, either with the value of `get_locale()` (site language) or `get_user_locale()` (user language with fallback to site language).

By enabling the user to select their preferred locale when editing the profile, we allow for greater personalization of the WordPress admin and therefore a better user experience.
The back end will be displayed in the user's individual locale while the locale used on the front end equals the one set for the whole site. If the user didn't specify a locale, the site's locale will be used as a fallback. The new `locale` property of the `WP_User` class can be used to retrieve the user's locale setting.

`load_theme_textdomain()`, `load_plugin_textdomain()` and `load_muplugin_textdomain()` now try to load the .mo file from the `wp-content/languages` directory first. After the introduction of language packs, translation files are more likely to be located there.

Known functions, classes, and methods are now auto-linked in Code Reference pages following #meta1483.
Note: Hook references are still linked via inline `@see` tags due to the unlikelihood of reliably matching for known hooks based on a RegEx pattern.

The `_network_option()` parameter order will be changing to accept `$network_id` first. The `_site_option()` functions will remain in use throughout core as our way of retrieving a network option for the current network.

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.

* Corrects phrasing used in the descriptions for and filters in `_n()` and `_nx()`, particularly with regard to the use of 'singular' instead of 'single' or '1', and 'plural' instead of 'not 1'.
* Adds example usage to `_n()`, `_nx()`, `_nx_noop()`, and `translate_nooped_plural()`.
* Adds hash notation `@return` doc for `_n_noop()` and `_nx_noop()`.
* Adds missing default values for the optional `$domain` parameter in several places.

The language dropdown now includes installed languages and all available translations when the filesystem is writable by WordPress.
Go to wp-admin/options-general.php, select one of the available translations, submit the form and let WordPress handle the rest.
Works for Multisite's Default Language too.
