* UART and BLE/GATT transports for a protobuf encoded RPC request/response protocol. * Custom framing protocol is used to frame a give message. * Requests/responses are divided into major "subsystems" which handle requests and create response messages. * Notification support, including mapping local events to RPC notifications by a given subsystem. * Meta responses for "no response" and "unlock needed". * Initial basic lock state support in a new core section, and allow specifying if a given RPC callback requires unlocked state or not. * Add behavior subsystem with full metadata support and examples of using callback to serialize a repeated field without extra stack space needed.
