* cmd: null-terminated command string, max 240 characters
* response: response buffer for VM's textual response
* rlen: size of the response buffer, cpcmd will not exceed this size
* but will cap the output, if its too large. Everything that
* did not fit into the buffer will be silently dropped
* response_code: return pointer for VM's error code
* return value: the size of the response. The caller can check if the buffer
* was large enough by comparing the return value and rlen
* NOTE: If the response buffer is not below 2 GB, cpcmd can sleep
