Now that nodes correctly populate position field in coding shreds, and
first_coding_index in erasure meta, the old code to maintain backward
compatibility can be removed.
The commit is working towards changing erasure coding schema to 32:64.
* Replaces KeyedAccount in create_executor().
* Refactors len to write_offset in write_program_data().
* Replaces KeyedAccount in write_program_data().
* Use transaction_context.get_key_of_account_at_index() in process_instruction_common().
* Renames next_first_instruction_account to program_account_index.
* Replaces program KeyedAccount by BorrowedAccount in process_instruction_common().
* Removes _program in process_instruction_common().
* Replaces first_account KeyedAccount by BorrowedAccount in process_instruction_common().
* Moves KeyedAccount lookup inside common_close_account().
* Replaces close_account, recipient_account and authority_account KeyedAccount by BorrowedAccount in common_close_account().
* run validator_exit_test sequentially
* limit validator exit run to its own serial run subset
add 10ms delay in the validator exit tests
* fix intermittent validator exit failure
* no sleep
* undo the code move
Current slot stats are removed when the slot is full or every 30 seconds
if the slot is before root:
https://github.com/solana-labs/solana/blob/493a8e234/ledger/src/blockstore.rs#L2017-L2027
In order to track if the slot is ultimately marked as dead or rooted and
emit more metrics, this commit expands lifetime of SlotStats while
bounding total size of cache using an LRU eviction policy.
