/**
* Get a message from either the content language or the user language.
*
* First, assemble a list of languages to attempt getting the message from. This
* chain begins with the requested language and its fallbacks and then continues with
* the content language and its fallbacks. For each language in the chain, the following
* process will occur (in this order):
* 1. If a language-specific override, i.e., [[MW:msg/lang]], is available, use that.
* Note: for the content language, there is no /lang subpage.
* 2. Fetch from the static CDB cache.
* 3. If available, check the database for fallback language overrides.
*
* This process provides a number of guarantees. When changing this code, make sure all
* of these guarantees are preserved.
* * If the requested language is *not* the content language, then the CDB cache for that
* specific language will take precedence over the root database page ([[MW:msg]]).
* * Fallbacks will be just that: fallbacks. A fallback language will never be reached if
* the message is available *anywhere* in the language for which it is a fallback.
*
* @param string $key The message key
* @param bool $useDB If true, look for the message in the DB, false
* to use only the compiled l10n cache.
* @param bool|string|object $langcode Code of the language to get the message for.
* - If string and a valid code, will create a standard language object
* - If string but not a valid code, will create a basic language object
* - If boolean and false, create object from the current users language
* - If boolean and true, create object from the wikis content language
* - If language object, use it as given
* @param bool $isFullKey Specifies whether $key is a two part key "msg/lang".
*
* @throws MWException When given an invalid key
* @return string|bool False if the message doesn't exist, otherwise the
* message (which can be empty)
