  Log:
  Make sigaltstack as per-threaded, because per-process sigaltstack state
  is useless for threaded programs, multiple threads can not share same
  stack.
  The alternative signal stack is private for thread, no lock is needed,
  the orignal P_ALTSTACK is now moved into td_pflags and renamed to
  TDP_ALTSTACK.
  For single thread or Linux clone() based threaded program, there is no
  semantic changed, because those programs only have one kernel thread
  in every process.
