These syscalls are not necessary on their own, and they give the false impression that a caller could set or get the thread name of any process in the system, which is not true. Therefore, move the functionality of these syscalls to be options in the prctl syscall, which makes it abundantly clear that these operations could only occur from a running thread in a process that sees other threads in that process only.
