-   o Code simplification and refactoring:
 
-     - Split sampled_guards_update_from_consensus() and
 
-       select_entry_guard_for_circuit() into subfunctions.
 
-       In entry_guards_update_primary() unite
 
-       three smartlist enumerations into one and move smartlist
 
-       comparison code out of the function. Closes ticket 21349.
