Returns the values associated with @key under @group_name
translated in the given @locale if available. If @locale is
%NULL then the current locale is assumed.
If @locale is to be non-%NULL, or if the current locale will change over
the lifetime of the #GKeyFile, it must be loaded with
%G_KEY_FILE_KEEP_TRANSLATIONS in order to load strings for all locales.
If @key cannot be found then %NULL is returned and @error is set
to #G_KEY_FILE_ERROR_KEY_NOT_FOUND. If the values associated
with @key cannot be interpreted or no suitable translations
can be found then the untranslated values are returned. The
returned array is %NULL-terminated, so @length may optionally
be %NULL.
