* Unifies SysvarCache filling in the runtime and tests.
Removes new_mock_with_sysvars_and_features()
Removes mock_process_instruction_with_sysvars().
Replaces from_keyed_account() by SysvarCache in vote processor.
* Replaces from_keyed_account() by SysvarCache in BPF loader.
* Adds TEST_DUPLICATE_PRIVILEGE_ESCALATION_SIGNER and TEST_DUPLICATE_PRIVILEGE_ESCALATION_WRITABLE.
* Moves CPI privilege verification out of deduplication loop.
* Makes error handling in BorrowedAccount optional.
Adds BorrowedAccount ::get_rent_epoch().
Exposes InstructionContext::get_index_in_transaction().
Turns accounts and account_keys into pinned boxed slices.
* Introduces "unsafe" to InvokeContext::push().
* Turns &TransactionContext into &mut TransactionContext in InvokeContext.
* Push and pop InstructionContext in InvokeContext.
Makes test_process_cross_program and test_native_invoke symmetric.
Removes the borrow check from test_invoke_context_verify.
* Removes keyed_accounts from prepare_instruction()
* Removes usage of invoke_stack.
* Removes keyed_accounts from program-test.
* Removes caller_write_privileges.
* Removes keyed_accounts from BPF parameter (de-)serialization.
* Turns compute_units_consumed of ProcessInstructionResult into a &mut parameter.
* Removes second nesting level from test_process_instruction_compute_budget().
* Makes test_process_cross_program and test_native_invoke symmetric.
* Unifies test_process_cross_program(), test_native_invoke() and test_process_instruction_compute_budget() into test_process_instruction().
* Adds TransactionContext, InstructionContext and BorrowedAccount.
* Redirects the usage of accounts in InvokeContext through TransactionContext.
Also use the types declared in transaction_context.rs everywhere.
* Adjusts all affected tests.
* Unifies all InstructionRecorders of a transaction into one.
* Stops explicitly compiling CPI instructions for recording,
uses the indices gathered from instruction_accounts instead.
* Removes message::Message from invoke_context.rs completely.
* Simplifies sol_invoke_signed() of program-test
* Start search for non program accounts at front (instead of the back).
Program and programdata accounts use rposition(), everything else uses position().
* Introduces InstructionAccount which is like AccountMeta but uses an index instead of a Pubkey
* Renames InvokeContext::create_message() to InvokeContext::prepare_instruction()
* Removes Message and CompiledInstruction from InvokeContext interfaces.
* Resolves TODOs of sol_invoke_signed() in program-test.
* Moves CompiledInstruction::visit_each_account() into invoke_context.rs
* Partial revert "Updates documentation around what needs to be passed in CPI. (#21633)"
* Enforces the program_id being passed explicitly by removing it from get_instruction_keyed_accounts().
* instruction_accounts => instructions_account
* Removes Rc from Rc<RefCell<AccountSharedData>> in the program-runtime.
* Adjusts tests in bpf_loader, system_instruction_processor, config_processor, vote_instruction and stake_instruction
* Removes Rc and RefCell from PreAccount
* Splits get_account() into find_index_of_account() and get_account_at_index()
in order to remove Rc from return type.
- Lets InvokeContext::process_cross_program_instruction() handle the first invocation depth too.
- Marks InvokeContext::verify(), InvokeContext::verify_and_update() and InvokeContext::process_executable_chain() private.
- Renames InvokeContext::process_cross_program_instruction() to InvokeContext::process_instruction().
- Removes InvokeContext::new_mock_with_sysvars().
* Moves create_message(), native_invoke() and process_cross_program_instruction()
from the InstructionProcessor to the InvokeContext so that they can have a useful "self" parameter.
* Moves InstructionProcessor into InvokeContext and Bank.
* Moves ExecuteDetailsTimings into its own file.
* Moves Executor into invoke_context.rs
* Moves PreAccount into its own file.
