    kernel - Add PROC_PDEATHSIG_CTL and PROC_PDEATHSIG_STATUS
    
    * Add PROC_PDEATHSIG_CTL and PROC_PDEATHSIG_STATUS to procctl(2).
    
      This follows the linux and freebsd semantics, however it should be noted
      that since the child of a fork() clears the setting, these semantics have
      a fork/exit race between an exiting parent and a child which has not
      yet setup its death wish.
    
    * Also fix a number of signal ranging checks.
