* Adds transaction_context and instruction_context where invoke_context.get_keyed_accounts() is used.
* Use instruction_context.get_instruction_data() instead of an explicit parameter.
* Removes instruction_data parameter from Executor::execute().
* Removes instruction_data parameter from ProcessInstructionWithContext.
* Replaces all use sites of get_sysvar_with_account_check by get_sysvar_with_account_check2.
* Removes get_sysvar_with_account_check.
* Renames get_sysvar_with_account_check2 to get_sysvar_with_account_check.
* Use visit_each_account_once() in CPI syscall to prevent duplicate accounts from being translated twice.
* remove unwrap() from runtime

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.
* Adds get_sysvar_with_account_check2 for ABIv2.
* Replaces get_signers() and get_sysvar_with_account_check() in system_instruction_processor.
* Replaces KeyedAccount by BorrowedAccount in nonce_keyed_account.
* Moves TransactionContext::get_program_key() to InstructionContext::get_program_key().
* Removes TransactionContext::get_loader_key().
* Test full program and loader executable account chain in BPF loader.
* Moves stack_height of the instruction_trace into InstructionContext.
* Uses nesting_level instead of stack_height internally in transaction_context.rs
* Uses the instruction_trace instead of the instruction_context_stack internally.
* Adds feature gate: record_instruction_in_transaction_context_push.
* Adds BorrowedAccount::check_sysvar().
* Adds BorrowedAccount::get_data_mut().
* Implements account resizing in BorrowedAccount.
* Exposes is_signer() and is_writable() in InstructionContext.
* Removes AccountMeta and get_instruction_accounts_metas().
* Makes throwing errors in BorrowedAccount optional.
* Removes result return values from BorrowedAccount.
* Replaces from_keyed_account() by SysvarCache in stake instruction.
* Replaces from_keyed_account() by SysvarCache in system instruction processor.
* Removes from_keyed_account().
Moves check_sysvar_keyed_account() into sysvar_cache.rs
* Removes tests which test for incorrectly serialized sysvars.
* 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.
