Add the Guava library to the tools

This changeset adds the Guava library to ADT and lint. (It is also a
prerequisite for the Lombok AST library which is added by a later CL.)

This changeset also uses the library in a few simple ways: It replaces
some custom I/O and collections code with calls into the equivalent
Guava methods, and it also adds the @Beta annotation on the various
"API" classes which are not yet stable.
