Integrate FMD GHOST into the fork choice rule to prevent "decoy flip flop attacks" discussed here.

  • Only consider an attestation in on_attestation if it is from the current or previous epoch (wrt wall clock time).
  • add a few tests

Note: this currently has bounce-attack as base branch for easy review. Will swap to v09x once bounce-attack is merged

@djrtwo djrtwo force-pushed the decoy-flip-flop branch 2 times, most recently from c28738f to 39eecfb Compare November 5, 2019 19:58
