HAL4RT — Functions arguments are empty in Surface layer header

dtc-16-01-01 section 7.5.2 C PSM and robotics/15-11-04 are a header of HAL's surface layer.
Most of functions declared in there have no arguments.

For example completed() function is declared in the header as follows,

int32_t completed();

However, in the Table 7.5 section 7.4.3.1 in page 21, completed() function is defined as follows.

ReturnCode completed(string command_id, ReturnCode status);
