• calculate_stake_points_and_credits 🔒
  for a given stake and vote_state, calculate how many points were earned (credits * stake) and new value for credits_observed were the points paid
• calculate_stake_rewards 🔒
  for a given stake and vote_state, calculate what distributions and what updates should be made returns a tuple in the case of a payout of:
• create_account
• create_account_with_activation_epoch
• create_lockup_stake_account
• create_stake_history_from_delegations

• redelegate_stake 🔒
• set_lockup
• split
• stake_from
• stake_weighted_credits_observed 🔒

• validate_delegated_amount 🔒
  Ensure the stake delegation amount is valid. This checks that the account meets the minimum balance requirements of delegated stake. If not, return an error.
• validate_split_amount 🔒
  Ensure the split amount is valid. This checks the source and destination accounts meet the minimum balance requirements, which is the rent exempt reserve plus the minimum stake delegation, and that the source account has enough lamports for the request split amount. If not, return an error.
