turned off - accessing userland memory. Now, arch_thread_enter_userspace() does that
  job, and as a result, may also fail.
* dump_thread() now directly prints the info of the current thread when used without
  argument (rather than iterating the thread list to look for the current thread).
* If arch_thread_init_tls() fails upon thread creation, the function will now return
  an error.
