* Fix bank hash not changing when no internal state has changed
* Fix unnecessary call to hash_internal_state
* Add blockhash into the bank_hash
* Add blockhash into the bank_hash and update tests
* Refactor accounts_db slot_hashes
* More clarity in comments
* Add clippy suggestion
* Grammar
* Fix compile after clippy made me break it
* Schooled by clippy
* credit_only_credits_forwarding
* whack transfer_now()
* fixup
* bench should retry the airdrop TX
* fixup
* try to make bench-exchange a bit more robust, informative
* Remove serialization of AccountStorageEntry fields
* Add metric for evaluating BankRc serialization time
* Serialize AppendVec current len
* Add dashboard metrics
* Move flush of AppendVecs to packaging thread
* change paths to something accounts_db (the singleton) owns, fixes SIGILL
* fail deserialize if paths don't work
serialize paths, too
* test that paths are populated from a bank snapshot
* accounts_index: RwLock per-account
Lots of lock contention on the accounts_index lock,
only take write-lock on accounts_index if we need to insert/remove an
account.
For updates, take a read-lock and then write-lock on the individual
account.
* Remove unneeded enumerate and add comments.
* Implement CreditOnlyLocks
* Update credit-only atomic on account load
* Update credit-only atomic after bank.freeze_lock; store credits if all credit-only lock references are dropped
* Commit credit-only credits on bank freeze
* Update core to CreditAccountLocks
* Impl credit-only in System Transfer
* Rework CreditAccountLocks, test, and fix bugs
* Review comments: Pass CreditAccountLocks by reference; Tighten up insert block
* Only store credits on completed slot
* Check balance in bench_exchange funding to ensure commit_credits has completed
* Add is_debitable info to KeyedAccount meta to pass into programs
* Reinstate CreditOnlyLocks check on lock_account
* Rework CreditAccountLocks to remove strong_count usage
* Add multi-threaded credit-only locks test
* Improve RwLocks usage
* Review comments: panic if bad things happen; tighter code
* Assert lock_accounts race does not happen
* Revert panic if bad things happen; not a bad thing
* Add credit-only debit/data check to verify_instruction
* Store credits and pass to accounts_db
* Add InstructionErrors and tests
* Relax account locks for credit-only accounts
