menubar.utils: Remove some (basically) dead code

Browse source 
This removes unused public functions from menubar.utils. This is not an
API break, because these functions were only added in commit
8d34201ec3, which is after v4.2. These new functions became
unused in commit e88f1e8735, not long after they were added.
