* RPC: Add App start, lock status - Add RPC commands Application start, lock status acquiring. - Write tests for RPC App system. - Replace Unit Tests application with CLI command. This is for CI needs and for tests that run application. * Fix NDEBUG build * Update PB submodule * Fix RPC print (ENABLE DEBUG PRINT!) * snprintf -> string_t * Fix Hard Fault (early mutex free) * printf -> string_t, format, enable tests * Update submodule: protobuf * Applications: rollback unit test naming scheme.
