  Modified files:
    lib/libc_r/uthread   uthread_fork.c 
    sys/kern             kern_fork.c kern_sig.c 
  Log:
  Properly copy the P_ALTSTACK flag in struct proc::p_flag to the child
  process on fork(2).
  
  It is the supposed behavior stated in the manpage of sigaction(2), and
  Solaris, NetBSD and FreeBSD 3-STABLE correctly do so.
  
  The previous fix against libc_r/uthread/uthread_fork.c fixed the
  problem only for the programs linked with libc_r, so back it out and
  fix fork(2) itself to help those not linked with libc_r as well.
