com.google.errorprone:error_prone_core: 2.0.19 -> 2.1.2

Other changes:

 - Remove references to warnings that were removed from Error Prone.

 - Suppress occurrences of a new warning, JdkObsolete. All of the warnings are
   about uses of LinkedList. We need to decide whether to use a different class
   or continue suppressing the warnings. I left TODOs, since each occurrence may
   need to be handled differently.
