Prefer Multimap subtypes and MultimapBuilder

Guava team recommends using the subinterfaces of Multimap, for the
same reasons they recommend using Set and List rather than Collection:
it documents expectations about ordering, uniqueness, and behavior of
equals.

They also recommends MultimapBuilder over specific Multimap
implementations, so callers don't have to know the specific key/value
behaviors of the individual implementations. The static factory
methods in the implementations will be removed in a later version.
