Repeated/Map field setter should accept a regular PHP array (#2817)

Accept regular PHP array for repeated/map setter. Existing map/repeated
field will be swapped by a clean map/repeated field. Then, elements in
the array will be added to the map/repeated field. All elements will be
type checked before adding.

See #2686 for detail.
