A VoteAccount may only wrap an account if the account owner is
solana_vote_program:id or equivalently this check returns true:
solana_vote_program::check_id(account.owner())
Unless struct fields are explicitly ignored in PartialEq implementation,
there are no compile-time checks that if more fields are added to the
struct, PartialEq implementation is accordingly updated.
Tracking mismatches between cached vote/stake accounts and accounts-db
in preparation of activating feature for updating rewards at
epoch-boundary using cached vote/stake accounts.
StakeAccount<Delegation> can only wrap a stake-state which is a
Delegation; whereas StakeAccount<()> wraps any account with stake state.
As a result, StakeAccount::<Delegation>::delegation() will return
Delegation instead of Option<Delegation>.
For backward compatibility, we can only serialize and deserialize
Stakes<Delegation>. However Bank caches Stakes<StakeAccount>. This type
mismatch incurs a conversion cost at epoch boundary when updating
EpochStakes.
This commit adds StakesEnum which allows EpochStakes to include either a
Stakes<StakeAccount> or Stakes<Delegation> and so bypass the conversion
cost between the two at the epoch boundary.
The commit makes values in stake_delegations map in Stakes struct
generic. Stakes<Delegation> is equivalent to the old code and is used
for backward compatibility in BankFieldsTo{Serialize,Deserialize}.
But banks cache Stakes<StakeAccount> which includes the entire stake
account and StakeState deserialized from account. Doing so, will remove
the need to load stake account from accounts-db when working with
stake-delegations.
The added type does sanity checks on the Account and stores deserialized
StakeState. Following commits will use this type instead of Delegation
in Stakes.
* Pass the sum of consumed compute units to cost_tracker
* cost model tracks builtins and bpf programs separately, enabling adjust block cost by actual bpf programs execution costs
* Copied nightly-only experimental `checked_add_(un)signed` implementation to sdk
* Add function to update cost tracker with execution cost adjustment
* Review suggestion - using enum instead of struct for CommitTransactionDetails

* review - rename variable to distinguish accumulated_consumed_units from individual compute_units_consumed
* not to use signed integer operations
* Review - using saturating_add_assign!(), and checked_*().unwrap_or()
* Review - using Ordering enum to cmp
* replace checked_ with saturating_
* review - remove unnecessary Option<>
* Review - add function to report number of non-zero units account to metrics
