Function rte_ctrl_thread_create has been replaced by rte_thread_create_control,
encouraging Linux users to switch from the pthread_t API to the rte_thread API.
However the rte_thread API does not provide wrappers for all pthread functions.
This commit introduces equivalent functions for pthread_timedjoin_np,
pthread_getname_np and pthread_cancel.
