This PR adds the missing
errsignal to theobi_driverclass. The signal was present in the interface, but never driven by the driver. Additionally, it is added to thesend_rtask of the driver, as all the other reponse phase signals are.As for the value the random subordinate generates for the
errsignal when callingsend_r, the approach fromaxi_testwas used and a new parameter of the random subordinate calledRandRespis used to determine if theerrsignal is randomized or always0(default for compatibility with other testbenches).
