  Modified files:
    sys/sys              umtx.h 
    sys/kern             kern_umtx.c 
  Log:
  Let _umtx_op directly return error code rather than from errno because
  errno can be tampered potentially by nested signal handle.
  Now all error codes are returned in negative value, positive value are
  reserved for future expansion.
