Add a prototype for rfork_thread().

pid_t rfork_thread(int forkflags, void *stack, int (*func)(void *arg),
                   void *arg);
A new process is created, presumably using RFMEM shared address space.
The child process switches to the supplied stack, which is set up with a
function call frame.  The function is called with the supplied arguement.
If the function returns, the return value will be used with _exit(2).
