lib: implement route map northbound

Browse source 
Based on the route map old CLI, implement the route map handling using
the exported functions.

Use a curry-like programming pattern avoid code repetition when
destroying match/set entries. This is needed by other daemons that
implement custom route map functions and need to pass to lib their
specific destroy functions.
