Tobias Reischmann 8c067bb86d MDL-27886 backup: Enabled unlocking of backup settings
The function is_locked was changed to determine only, if the
dependency_setting want's the dependent setting to be locked.
In the previous version, is_locked did not only check, if the
dependency_setting want's the setting to be locked, but also if the
setting was already locked. A recursive call to the status of the
dependent setting leaded to problems, when unlocking locked settings.

Also the PHPDOC of the is_locked was adjusted to coincide with the current
usage in backup_ui_settings->is_changeable() and
base_setting->set_status(). In both functions all dependency_settings of
a setting are iterated to check if this setting should be or is LOCKED_BY_HIERARCHY.
The actual state of the setting was therefore either checked beforehand
or is not interesting, since the question is, if it shall be changed.
