The kernel now maintains the pthread_internal_t::tid field for us, and __clone was only used in one place so let's inline it so we don't have to leave such a dangerous function lying around. Also rename files to match their content and remove some useless #includes. Change-Id: I24299fb4a940e394de75f864ee36fdabbd9438f9
