- Move decode_other() from standard to tool_log\helper\reader trait.
- Change all ocurrences to "use" the trait method. But a unit test.
- Duplicate the admin lang strings in database and use them.
- An incorrect phpdoc @package.
This reverses the references used for global $USER and $SESSION,
the reason is that PHP does not allow references to references.
$USER is a reference to $GLOBALS['USER'] which means we cannot
put any references to it. Solution is to store the current user and session
objects in $GLOBALS['USER'] and $GLOBALS['SESSIOn'] are reference
them in $_SESSION.
This patch makes the session code behave the same way in CLI,
phpunit and normal web requests - this allows use to finally
unit test most aspects of the session code in Moodle.
