This change prevents zero-cost computation of hash functions on
unbound number of zero-length slices of data. The cost for each slice
is at least equal to the base cost of a memory operation, but could be
more for longer slices.
* Moves TransactionContext::get_program_key() to InstructionContext::get_program_key().

* Makes throwing errors in BorrowedAccount optional.
* Removes result return values from BorrowedAccount.
* 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.
* 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
* 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.
* impl AbiExample for BuiltinPrograms
* Moves the Executor dyn Trait to instruction_processor.rs
* Moves the Logger dyn Trait as well as the ic_msg and ic_logger_msg macros to log_collector.rs,
and moves the stable_log to stable_log.rs
* Moves the ComputeMeter dyn Trait to invoke_context.rs
* Moves the InvokeContext dyn Trait and the ProcessInstructionWithContext type to invoke_context.rs
* Updates cargo files.
* Re-export InvokeContext in program-test

* Adds missing loader account in uses of MockInvokeContext.
* Use keyed_account_at_index() when accessing keyed_accounts.
* Makes sysvar interface consistent between ThisInvokeContext and MockInvokeContext,
in order to add InvokeContext::get_sysvars().
