* Transition getter functions to not use scratch buffer * Remove scratch buffer from ext_get_storage * Remove scratch buffer from ext_call * Remove scratch buffer from ext_instantiate * Add ext_input and remove scratch buffer * Rework error handling (changes RPC exposed data) * ext_return passes a flags field instead of a return code * Flags is only for seal and not for the caller * flags: u32 replaced status_code: u8 in RPC exposed type * API functions use a unified error type (ReturnCode) * ext_transfer now traps on error to be consistent with call and instantiate * Remove the no longer used `Dispatched` event * Updated inline documentation * Prevent skipping of copying the output for getter API * Return gas_consumed from the RPC contracts call interface * Updated COMPLEXTITY.md * Rename ext_gas_price to ext_weight_to_fee * Align comments with spaces * Removed no longer used `ExecError` * Remove possible panic in `from_typed_value` * Use a struct as associated data for SpecialTrap::Return * Fix nits in COMPLEXITY.md * Renamed SpecialTrap to TrapReason * Fix test * Finish renaming special_trap -> trap_reason * Remove no longer used get_runtime_storage * fixup! Remove no longer used get_runtime_storage * Removed tabs for comment aligment
