The MXS_MODULDE object now contains optinal pointers for functions to be called att process and thread startup and shutdown. Since the functions were added to the end, strictly speaking, all structures would not have needed to have been modified, but better to be explicit. In a subsequent change, these will be called. C++ does not support flexible arrays, so for the time being C++ modules are restricted to 10 parameters. Better approach is to factor out the parameters to a separate array and then just store a pointer to that array in MXS_MODULE.
