Refactoring to support more annotation types.

Split the actual annotation handling logic out of AnnotationVisitor,
instead delegating to a new AnnotationHandler interface. The visitor now
simply takes a map of annotation name to handler, and delegate all the
interesting work.

Create a new GreylistAnnotationHandler for dealing with the existing
@UnsupportedAppUsage annotations.

Add support for writing to a whitelist file too, though this is not used
yet in this CL. A new parameter --write-whitelist specifies a filename to
write this to.

Also refactor the tests along similar lines.
