/*
 * Terminate a thread and release rights and memory.

 * Intended to be used by threading libraries to provide a clean way for
 * threads to terminate themselves. The resources a thread wouldn't be able
 * to release without this call when terminating itself are its
 * last reference to its kernel port, its reply port, and its stack.
 *
 * This call is semantically equivalent to :
 *  - mach_port_deallocate(task, thread_name);
 *  - if (reply_port != MACH_PORT_NULL)
 *      mach_port_destroy(task, reply_port);
 *  - if ((address != 0) || (size != 0))
 *      vm_deallocate(task, address, size)
 *  - thread_terminate(thread)
 *
 * Implemented as a simple routine so a reply port isn't required.
